According to the "Beijing Release" WeChat WeChat official account news, the Beijing Center for Disease Control and Prevention issued a health reminder:Covid-19 can effectively prevent Covid-19 infection through close contact and respiratory droplets transmission. Personal protection such as wearing a mask, washing hands frequently, regular ventilation and keeping a safe social distance can effectively prevent infection. In order to better protect the health of themselves and their families, please ask the general public and friends to participate in, understand, support and cooperate with various epidemic prevention and control measures, earnestly fulfill their personal epidemic prevention responsibilities, scientifically prevent epidemics, and be the first responsible person for their own health.

One is to wear a mask. Wear masks in indoor and outdoor crowded places, when taking elevators or public transport; When fever, dry cough, fatigue, sore throat and other symptoms appear, it is recommended to wear a medical surgical mask or above when seeking medical treatment in the hospital; Masks should be replaced in time, and the cumulative wearing time of each mask should not exceed 8 hours.

The second is to wash your hands frequently. When going out and returning home, caring for the elderly, children and patients, touching the mouth, eyes, nose, coughing or sneezing, cleaning up garbage, touching public facilities such as express delivery, elevator buttons, door handles, etc., you should wash your hands or disinfect your hands in time.

The third is constant ventilation. Open the window for ventilation at proper time, 2 ~ 3 times a day for 20 ~ 30 minutes each time; When there are many people at home, patients or visitors, it is recommended to open the window for ventilation; When there are isolated people at home, the room where they are located should close the door and open the window separately for ventilation.

The fourth is to gather less. Try not to go to crowded places with poor air circulation, stay away from people with fever or cough symptoms, reduce gathering activities and maintain a safe social distance.

The fifth is to maintain environmental sanitation. Daily household cleaning is the main task, and preventive disinfection is carried out when necessary; Kitchen utensils, countertops, tableware, etc. should be cleaned and disinfected in time; Regularly clean and disinfect the sanitary ware and floor in the toilet. When the surface is dirty or moldy, it should be cleaned and disinfected in time; Cover the toilet before flushing and keep the trap water sealed.

Sixth, actively vaccinate COVID-19 vaccine. The whole population in Covid-19 is susceptible, and the elderly are the most vulnerable group, with a high proportion of basic diseases. They are the high-risk group that will cause severe illness after being infected with Covid-19. Vaccination with COVID-19 vaccine is always one of the most effective preventive measures. It is suggested that the elderly who meet the vaccination conditions should be vaccinated as soon as possible, and the booster immunization should be completed as soon as possible after three months of complete vaccination.

Seventh, develop a healthy lifestyle. Strengthen physical exercise, adhere to the law of work and rest, ensure adequate sleep, maintain a healthy mentality, eat healthily, quit smoking and limit alcohol, maintain a healthy mentality, and do not believe in rumors or spread rumors.

Eighth, do a good job in health monitoring. Make good use of nucleic acid detection and antigen self-test. If you have symptoms such as fever and dry cough, don’t go to work or school with illness, don’t take part in social activities, don’t take public transportation, wear a mask, and go to the hospital fever clinic for investigation in time to reduce the risk of family transmission and cooperate with the implementation of various prevention and control measures.

　　[car home industry]　　In the movie "shaolin soccer", A Xing, omega supreme’s leg, played by Stephen Chow, looked up and muttered "I feel that they are all back" when he saw your other disciples find their state and kill the quartet. At the beginning of this month, when some car companies announced the sales volume in April first, the reaction of the outside world was the same as A Xing’s. They thought that all car companies had recovered their status and the China auto market had returned to that era full of growth.

　　However, contrary to expectations, the beauty of the past is only suitable for recollection, and it is difficult to find it back.

　　According to car home’s incomplete statistics, 24 car companies have released April sales data, of which 11 companies still cannot achieve positive sales growth year-on-year; From the perspective of cumulative sales in 2020, only one company, FAW Hongqi, can achieve positive year-on-year sales growth from January to April, and the cumulative sales of "head car companies" such as SAIC Volkswagen, SAIC GM and SAIC-GM-Wuling have dropped by as much as 50.4%, 47.7% and 46.7% respectively.

　　Next, let’s comment on the sales performance of car companies in April.

Joint venture car companies: What about good retaliatory consumption?

　　Looking at the sales performance of joint venture car companies in April, it is not difficult to find that the legendary "retaliatory consumption" has not arrived. Among the 11 joint venture car companies, only 5 can achieve positive growth in April. Unfortunately, SAIC Volkswagen and SAIC-GM, the former sales overlords, are not among them.

　　As a resident player of Top 3 in China passenger car market, SAIC-GM achieved 110,002 vehicles in April, down 12.4% year-on-year, and its sales volume was lower than that of SAIC-Volkswagen, SAIC-GM Wuling and Changan Automobile. Before FAW-Volkswagen announced its sales volume, SAIC-GM had already lost the top three.

"Pioneer"

　　According to Shi Hong, deputy general manager of SAIC-GM and general manager of SAIC-GM Sales Company, from February to March in 2020, SAIC-GM devoted all its energy to supporting dealers, and began to officially rush sales in April. Like other car companies, SAIC-GM also regards product offensive as the biggest magic weapon to rush sales. According to statistics, in April alone, the company launched seven new cars through "cloud listing", including many heavy models such as Pioneer and Cadillac CT4.

　　In fact, for SAIC-GM, the biggest change in 2020 is not the product offensive or the organizational structure, but that this enterprise has finally abandoned the radical "all-in-one three-cylinder strategy". In April, the new Yinglang, the new Ke Lu Ze and other previous "all-in-one three-cylinder" models all launched four-cylinder engine versions. Giving up "persuasion" and catering to China consumers is the hope of SAIC-GM in 2020.

　　For Changan Ford, which has been trying to revive, it is not easy to sell 20,465 new cars in April and achieve a positive growth of 38.3% year-on-year. We should know that according to the statistical caliber of Changan Automobile, Changan Ford achieved positive sales growth in only one month (December) in 2019, but after entering 2020, the company has achieved positive growth twice in January and April, which has given Changan Ford a shot in the arm.

　　Since October 2018, in order to reverse the unfavorable situation in China, Ford Motor Co., Ltd. has not started to improve its position in the China market, and has listed the China market and the North American market as the company’s two core markets. Ford China directly reports to the global headquarters; Since then, Chen Anning, a veteran, has been appointed as Vice President of Ford Motor Company Group and President and CEO of Ford Motor Company China.

『(|)』

　　In September, 2019, Ford Motor Company set up a research institute for Changan Ford to enhance its R&D capability, accelerate product upgrading and intelligent manufacturing level, and launch a revival offensive with products that are more in line with China consumers’ aesthetic and usage preferences. In the "acceleration plan" announced at that time, Changan Ford will launch more than 18 new products in the middle of 2019 -2021, including 5 new energy vehicles.

　　From the perspective of sales in April 2020, Changan Ford’s self-help did work. Ruiji, which was just launched by this company at the end of 2019, surpassed Fox and Forex in April and became the "new thigh" of Changan Ford’s sales. The first model launched in the "acceleration plan" has achieved such results. After the sixth generation of explorers went on the market in June and the product offensive was officially rolled out, Changan Ford is very hopeful to turn around the crisis in 2020.

Mazda CX-30

　　Changan Mazda sold 11,761 vehicles in April, a year-on-year increase of 36.8%. Unlike Mazda’s overseas painting style of "not pushing a new car for two years", Changan Mazda’s heavy product Mazda CX-30 has now started pre-sale and will be listed on May 28th. For Changan Mazda, whose product line is relatively thin and new products are launched slowly, the sales performance of Mazda CX-30 will directly determine the future development pattern of this enterprise.

China car companies: the red flag won glory this time.

　　As of press time, a total of nine China auto companies announced their sales results in April, among which five companies’ sales increased year-on-year, and the overall situation was still optimistic.

　　In April, SAIC-GM-Wuling won the second place in China passenger car market, only selling 200 cars less than SAIC-Volkswagen. Strangely enough, while other companies were growing month-on-month, the sales volume of SAIC-GM-Wuling declined month-on-month. From this point of view, this company may have got rid of the impact of the epidemic.

　　Although the sales volume has achieved continuous positive year-on-year growth, SAIC-GM-Wuling has also made a lot of "blood" for this. It is reported that in order to stimulate automobile consumption, SAIC-GM-Wuling launched a total of 2 billion yuan in car purchase subsidies twice in February-April, covering all its models such as commercial vehicles, special vehicles, passenger cars and new energy vehicles; During the "May 1" period, this enterprise issued another 1.5 billion yuan travel coupons. When many enterprises reduced their costs by means of "salary reduction and layoffs", SAIC-GM-Wuling’s "retrograde" was full of enthusiasm.

　　In order to further increase sales, SAIC-GM-Wuling also planned a product offensive. It is understood that the company will launch 10 new cars in 2020, of which 6 are brand-new models and 4 are new models; Wuling brand will also launch a brand-new brand strategic plan during the year. Perhaps the end of 2020 is the most fair and objective time to evaluate the sales performance of SAIC-GM-Wuling.

　　BYD achieved sales of 31,809 vehicles in April, a year-on-year decrease of 15.9%; From January to April, the cumulative sales volume was 93,082 vehicles, a year-on-year decrease of 40.1%. Although the sales target for 2020 has not yet been announced, it is not easy for BYD to maintain the year-on-year sales even in terms of current sales results.

"Han"

　　In terms of sales structure, BYD sold 18,814 fuel vehicles in April, a year-on-year increase of 36%; 12,995 new energy vehicles were sold, down 45.9% compared with the same period last year. For BYD, the biggest attraction in 2020 is the upcoming listing in June, equipped with self-developed Ferrous lithium phosphate blade battery technology, BYD DiPilot intelligent driver assistance system and DiLink 3.0 intelligent network connection system.

　　For this car, BYD executives are very confident. Zhao Changjiang, general manager of BYD Auto Sales Co., Ltd. even publicly published on social media such remarks as "Tesla’s card is finished, it’s our turn to play" and "Han has surpassed Tesla in acceleration, battery life and charging speed, and in addition, the assisted driving is at the same level". However, under the introduction of the new subsidy policy and the price drop of Model 3, Han, who has not yet been listed, is indeed facing no small challenge. Whether this car can finally break through the interception of Model 3 and lead BYD to find its state remains to be tested by the market.

　　For an old brand with a new face, FAW Hongqi’s recent sales performance is excellent. In April, the company’s sales reached 14,500 vehicles, a year-on-year increase of 168%; From January to April, the cumulative sales volume exceeded 39,500 vehicles, and it was the only company (as of press time) that achieved positive growth in cumulative sales volume from January to April. In this regard, Hongqi did win glory for China brand.

Red Flag H9

　　However, it must be admitted that the reason why the cumulative sales volume increased year-on-year was also caused by the low sales base of FAW Hongqi. In addition, despite the rapid sales growth of this company, it has only completed one-fifth of its sales target of 200,000 vehicles so far, and 2020 is still full of pressure for FAW Hongqi.

　　In terms of products, the main action of FAW Hongqi in 2020 is to bring the medium and large-sized red flag H9 designed by former Rolls-Royce design director Giles Taylor and China designer Ding Yangfeng to the market, and release the pure electric SUV red flag E115. However, considering the positioning of these two products, their prices will certainly not be too close to the people, and it is not known how much they can contribute to Hongqi’s sales target.

Luxury brand: "overlord" translocation

　　Before 2019, Cadillac was the most detached existence among second-tier luxury brands, but when Lexus continued to heat up, Cadillac’s dominance of second-tier luxury brands was constantly threatened. After entering 2020, the competition in the second-tier luxury brand market suddenly escalated. Lexus officially defeated Cadillac with a total of 51,167 vehicles and became the new "overlord" in this field.

Cadillac CT4』

　　Since the second half of 2019, Cadillac began to switch between new and old products. The original sales models Cadillac ATS-L and Cadillac XTS were discontinued one after another. The brand once faced the dilemma of no car to sell. However, with the launch of Cadillac CT5 and Cadillac CT4, the company’s "3+3" product layout has been formed, officially bidding farewell to the most difficult period.

　　Compared with Cadillac, which is about to switch products, Lexus, which is currently on the "throne", is not easy. In terms of production capacity, Toyota has decided to cut the production capacity of Japanese factories by 50% in May and 40% in June. As a result, Lexus, which has not achieved domestic production, will encounter a bottleneck in production capacity supply, and this is also the best time for Cadillac to overtake.

"lexus es"

　　Although it is impossible to compete with Cadillac and Lexus for the time being, compared with itself, Volvo’s report card in April is quite excellent, with a sales volume of 14,698 vehicles and a year-on-year increase of 21%, setting a new record for the company’s sales in China in April. The monthly sales of its main model Volvo XC60 increased by 22% year-on-year, which also set the highest monthly sales record of Volvo Cars in China market.

　　Editor’s summary:More than half of the 24 car companies achieved positive sales growth in April. Although this report card is not bad, it obviously falls short of the expectation of "retaliatory consumption" from the outside world. Although compared with the first quarter, the sales performance of car companies rebounded significantly in April, it was still not enough to make up for the trauma caused by the previous decline in sales.

　　However, compared with before the epidemic, the "skills" of car companies are obviously richer. They have learned how to better market and sell cars online, and also learned how to achieve win-win results and mutual benefit with dealers. As long as the car companies can continue to carry forward these "skills", it is only a matter of time before they can find their normal state and achieve further sales growth.

　　What the human brain thinks is the most difficult thing to guess in the world, let alone control it. The 16th edition of this newspaper reported on July 11th that the United States and Russia secretly developed "brain-controlled weapons". On November 28th in Washington post, USA, Janet Moliis, President and CEO of M2 Technology Co., Ltd. in the United States, was reported in detail about the latest development of "brain-controlled weapons".

　　Implanting brain control chips to create double-faced agents

　　The introduction on the website of American M2 Technology Co., Ltd. is extremely simple: "The president and CEO of the company is Janet Moliis, and the vice president and chairman is Chris Moliis; The company’s main business is the development and deployment of non-lethal weapons, providing research and development support for non-lethal weapons for the US Marine Corps, Army, Federal Bureau of Investigation, argon National Laboratory and Lawrence Livermore National Laboratory; Strategic planning for providing non-lethal weapons for Marine Corps System Command and Army Combat Laboratory; Provide non-lethal weapons for the Marine Corps and the Army in actual combat. "

　　In contrast to the company profile with a few words, it is the dazzling aura on the head of the female boss Janet Moliis: senior policy analyst of the US Global Strategy Committee, strategic planner of non-lethal weapons in various US government departments, congressional office, director of the project department and R&D department of the National Security Policy Committee, general adviser of the strategic deployment of non-lethal weapons in the US Army Navy and Marine Corps, member of the Pentagon’s non-lethal weapons R&D and deployment Committee, and senior anti-terrorist action consultant of the White House …

　　What earned Moliis such honor was brain-controlled weapons under the banner of "non-lethal weapons".

　　In the tribal areas of Pakistan bordering Afghanistan, "Abdullah A" is an out-and-out fanatical militant. Although he was born in an Arab family in the United States and received higher education in the United States, he kept his mouth shut and even talked in his sleep with extreme religious language and anti-American sentiment. What he did made him the backbone of local Taliban armed forces and al-Qaeda elements. However, "Abdullah B" is a loyal American anti-terrorism agent. He continuously sends the information of Taliban militants and al-Qaeda elements in tribal areas to the headquarters, allowing the drones of the US military and CIA in Afghanistan to carry missiles, frequently causing fatal blows to terrorist organizations. Taliban armed forces and Al Qaeda have always suspected that there is an "insider" and have repeatedly examined and tested "Abdullah A", but they have not found any flaws, so that psychological warfare experts of Taliban armed forces and bases all said: "Unless Abdullah can split his personality, he can never be an American spy!"

　　In fact, "Abdullah A" and "Abdullah B" are the same person, and his real identity is the American anti-terrorism agent. And let him achieve "split personality" and stand all kinds of tests, it is the brain-controlled weapon developed by M2 Technology Company led by Moliis-a microchip deeply embedded in his body. This microchip controls Abdullah’s brain thinking, so that when he faces the test of terrorist organizations, he acts absolutely like an extremist without any deviation. Abdullah himself became Moliis’s brain control weapon.

　　Going into actual combat in Iraq, the enemy surrendered voluntarily.

　　Moliis and her M2 company, as well as the Pentagon and the CIA, refused to comment on brain-controlled weapons, but an American news source confirmed: "Moliis’s brain-controlled anti-terrorism agents have been active in Iraq, Afghanistan, Sudan and other parts of the world, and are playing an increasingly important role."

　　Moliis’s "brain-controlled anti-terrorism agents" should be her "advanced products", and more "brain-controlled weapons" will be used against enemy personnel. According to Washington Post Military Weekly reported on November 28th, insiders of Pentagon and CIA revealed that on the evening of October 23rd, 2007, in the "triangle of death" in northern Iraq, American troops stationed in Iraq were engaged in fierce fighting with anti-American armed forces. Just as the American field commander was at a loss, the Baghdad headquarters said it would send reinforcements quickly. To the great confusion of American field commanders, only five Americans arrived by helicopter an hour later! They are technicians from Moliis Company. Under the puzzled eyes of American officers and men, technicians quickly set up an instrument the size of a desktop computer and aimed it at the anti-American armed forces. Then something happened that shocked the American officers and men-in less than five minutes, the gunfire stopped at the anti-American armed position, and then the armed men knelt on the ground, prayed devoutly, and threw their weapons out of the position to express their surrender. After preliminary interrogation of the anti-American armed forces, American commanders learned that they had just heard the voice of the "prophet" and asked them to lay down their arms and surrender together.

　　The same report also said that on November 2, 2007, in Sadr City, Baghdad, the stubborn Sadr armed forces "Al-Quds Revolutionary Brigade" mysteriously abandoned their weapons and fled collectively-more than 230 armed men abandoned their checkpoints, strongholds and positions, leaving behind all kinds of weapons they regarded as their lives, radio stations, chariots and other logistics equipment, and "into thin air" overnight. The US military officers and men who fought against the "Holy City Revolutionary Brigade" confirmed afterwards that the technicians of Moliis Company had been "busy" at the scene before the incident …

　　Science fiction-like "brain-controlled weapons" have brought huge profits to Moliis, and Moliis’s companies now earn "hundreds of millions of dollars" every year, all from the US war on terrorism.

　　Adhering to the mantle of CIA, developing "brain-controlled weapons"

　　Janet Moliis, 52, was born in Massachusetts, USA, where she grew up and completed her college education. Moliis is a sci-fi fan. In the 18 years after graduating from college, he was obsessed with the creation of sci-fi novels and published dozens of influential sci-fi works. Moliis’s father-in-law also confirmed: "She is still a very good musician, full of passion!"

　　The creation and passion of science fiction gave Moliis access to the research history and related files of "brain-controlled weapons" in the United States. In 1946, President Truman secretly implemented the "paper clip project" and brought 765 German scientists, engineers and technicians to the United States, including experts in psychological warfare. In December 1947, when the National Security Council held its first meeting, JamesVincentForrestal, then Secretary of Defense, urged the CIA to start a secret war against the Soviet Union. Under this great background, CIA agents became interested in the study of how to destroy or control people’s thinking, and launched the earliest "brain control experiment". Since then, the CIA has successively carried out the research projects of "brain-controlled weapons" code-named "Bluebird", "Articek", "Ma Coutela" and "MK Research", and brought in Canada and Britain. In 1973, Richard Helms, then director of the CIA, ordered the destruction of all records of the MK research project after learning that the US Congress would investigate the research on brain-controlled weapons.

　　In 1973, Moliis and her husband both joined the expert group of the American Council on Foreign Relations, which gave them the opportunity to contact the US military and intelligence agencies and vigorously peddle the concept of "non-lethal weapons". Moliis often lobbies White House policymakers and Pentagon generals: "Non-lethal weapons can defeat the enemy without universal lethality. Why not invest?" Perhaps the concept is too advanced, and Moliis’s lobbying has not been responded by American policymakers for many years.

　　In 1992, Moliis met General Zinni, then commander of the Central Command. The general told Moliis about his distress: "My Somali troops often face mass incidents, such as large-scale demonstrations and mass robberies. A few gunmen are mixed in the crowd and shoot at us, but we can’t use weapons."

　　Moliis, who got this information, immediately snared the relevant personnel who had participated in the research project of "brain-controlled weapons" that she saw in the declassified files, and soon sent a non-lethal weapon "sticky foam" to Admiral Zinni-an adhesive that could hold the other party in place for half an hour and could not move. In 1993, when Zinni’s troops escorted the UN peacekeeping forces into Somalia, the "human bubble" came in handy. General Zinni recalled: "I was just a little boy sticking things around, and members of Congress showed great interest. I duly let Ms. Moliis come out, and she made friends with the dignitaries on Capitol Hill. In 1995, Congress established a joint project office for non-lethal weapons, which was led by the Marine Corps, and all arms and services participated, with an annual budget of 25 million US dollars. "

　　At this time, Moliis saw the business opportunity, and immediately established M2 Technology Co., Ltd. with her husband to contract the research and development projects of the Non-lethal Weapons Joint Project Department. The huge profits made Moliis Command Company quickly lock in its core research object "brain-controlled weapons". According to relevant documents, Moliis put forward a new concept of "brain-controlled weapon" on the basis of CIA research in 1998, and formally initiated the project development in 2003. Eighteen months later, he launched a portable "brain-controlled weapon" system and put it into practical test.

　　What exactly is Moliis’s "brain-controlled weapon"? Relevant literature shows that human emotions need to be cloned before making brain-controlled weapons. Thousands of emotional brain wave samples in the database are analyzed by supercomputer to understand the corresponding relationship between psychological characteristics and brain wave shapes. Then, these "emotional signal strings" are stored in another computer, and these "living signals" are transmitted to the human body by radio to "silently change the emotional state of human beings", thus manipulating the psychology and emotions of the target object and affecting its actions.

　　I am worried that if I don’t speed up research and development, I will be overtaken by Russia.

　　However, the harm and potential threat of "brain-controlled weapons" have also aroused serious concern of scientists in various countries, because once such weapons are abused, they can fundamentally control people. Whether in private houses, public places, industrial places, or public and private means of transportation, the secretly selected subjects will be affected by the radioactivity containing chemical and biological stimuli emitted by this "mysterious weapon". After a long time, the subjects will be socially isolated and their immunity will decline, which will lead to various diseases and even death …

　　In fact, the CIA’s laboratory that conducted "brain-controlled weapons" in the past had a series of lawsuits in Canada and the mainland, which gave huge compensation to some victims and damaged the reputation of the governments of the United States, Canada and Britain.

　　However, Moliis, who has tasted the sweetness, doesn’t seem to mind. She often says that according to some declassified data, Russia has a "long history" in the research of brain-controlled weapons. After the disintegration of the Soviet Union, while Russian talents were "poached" and a considerable number of military scientific research projects were cancelled, some top scientists and related projects related to brain control research were completely preserved. The implication is that if she doesn’t continue her research in this field, Russia will surpass the United States sooner or later. Moliis’s remarks are very effective in the increasingly tense relationship between Russia and the United States. (Special correspondent Yu Dong)

Since the high brush was added to the 13 Pro series last year, the industry is looking forward to what new features the iPhone 14 series will have this year. As a senior fruit fan, I also started the iPhone 14 Pro at the first time, enjoying the new experience brought by the new iPhone, and sharing some practical accessories.

Since the iPhone began to take the "environmental protection" route, the charging head also needs to be purchased by users themselves. Therefore, after upgrading to iPhone 14 Pro, the first accessory I purchased was this charging head of Mommie.

In terms of color, there are four colors corresponding to this charging head: elegant white, vitality purple, far peak blue and obsidian black. This year, the new iPhone 14pro is dark purple, and I also bought a purple charging head with the wind. It’s clean, elegant and beautiful!

Momis, the charging head, is very compact and easy to store. And the original charging head of the official 5V1A is much smaller! The charging head supports PD protocol, and the maximum charging power is 20W. I can charge my iPhone 14 Pro at full speed.

For daily use in the office, I always choose this charging head for charging. The charging head can be completely placed in the palm of my hand, and the whole weight is only about 33g, which is excellent for both business trips and daily use.

In terms of charging, you can charge 60% of the electricity in 30 minutes, and the charging speed is excellent! It is nearly 4 times better than Apple’s original charging effect! Fast charging greatly solves the embarrassing situation of fast power failure and emergency charging!

After starting with the iPhone 14 Pro, the most basic and important thing is to start with a tempered film. The selling points of mobile phone films on the market are different and have their own characteristics. The film I am looking at has only two requirements, one is high definition, which can well reflect the display effect of the mobile phone screen, so all films that prevent blue light, eye protection and voyeurism will pass. The second point is that the film should be strong and scratch-resistant. Finally, the tempered glass film from Belgin was selected.

The price of this film is not low, almost 100+ yuan. From the packaging point of view, this film factory is equipped with a "film artifact", which allows novices to easily paste it.

The film pasting process is very simple, just pick up the film, put the phone in the mold and align it. Then wipe the screen of the mobile phone clean, tear off the lower sticker of the film and stick it on the mobile phone to squeeze out bubbles.

Belgin toughened film pasting mold is very simple to use. Slots are arranged on both sides of the volume key and the power key of the mobile phone, so that the mobile phone can not be put in the wrong direction, and the mobile phone can be fixed better at the same time.

After pasting, tear the protective film on the front of the film to finish pasting.

Belgin tempered film fits perfectly with iPhone 14 Pro, and the opening is also completely compatible. Because it is a high-definition film, it can fully display the screen quality of the iPhone 14 Pro and restore the color to the extreme.

The thickness of the film is moderate, and there is no feeling of cutting hands when swiping from the edge of the phone to the screen. Oil-repellent layer can well prevent fingerprints and other oil stains. During this period of use, fingers slide smoothly on the screen. If I choose a film for the iPhone 14 Pro, I will first recommend this toughened film from Belgin.

For people who often go out for meetings or business trips, the mobile power supply is also one of the necessary equipment. This time, I bought the Mommie transparent magnetic power supply.

Just looking at the appearance, you can see that this is a product with full sense of technology. The appearance is made of transparent high-permeability tempered glass, similar to the GameBoy thin game machine we played when we were young. The internal circuit board and coil can be seen at a glance. Just putting this product on the table has a cool feeling.

The back is designed with a folding bracket, which can stand on the desktop conveniently. No matter whether it is a vertical screen to brush a small video or a horizontal screen to brush a drama, it can be firmly absorbed, and it is easy to use to catch a drama video.

Through the magnetic device, the iPhone 14 Pro can be firmly attached to the power supply. At the bottom are the power switch and the power indicator. The side is a Type-C interface, which supports wired input and output power, and wired charging is also a fast charge of 20 watts.

Momis transparent magnetic power supply weighs 200g, and playing with your mobile phone when charging will increase the weight of your hands, so it is more recommended to use it on the desktop. When the back is magnetically attracted, it will not block the camera.

In addition, this Type-C interface with MOMMIS transparent magnetic attraction can also be used to charge other devices with wires.

In terms of charging speed, wireless charging can support a charging rate of up to 15W, and connecting the Type-C data cable can support a charging rate of up to 20W, which fully meets the charging requirements for daily use, and can be wired and wireless charging at the same time, without any pressure.

The mobile phone case is one of the accessories I must buy after buying a mobile phone. Personally, I prefer the mobile phone case made of Kevlar, so I also bought the mobile phone case of PITAKA’s house with Kevlar ceiling at the first time.

In addition to Kevlar material, this mobile phone case is also embedded with MagSafe magnetic attraction module, which can be better adapted to other magnetic attraction accessories.

This PITAKA magnetic mobile phone case is a half-package design, and the buttons on the side can be directly pressed by hand, retaining the touch of the original machine. There is no package at all on the interface, so there will be no case that the shell blocks the interface when plugging in different brands of data cables.

I like the two main points of PITAKA mobile phone case: the appearance is fashionable, unique and quality, at the same time, the material is light and comfortable, and the original machine is "slippery". If let me recommend a practical+feel good mobile phone case, I will not hesitate to recommend PITAKA as a mobile phone case.

After I bought the iPhone 14 Pro, I also bought a lot of mobile phone cases, including liquid silicone, Kevlar (aramid fiber), TPU and various cases with flannel. Among them, I love a mobile phone case very much, that is, the UAG mobile phone case with the best "protection" performance.

After taking out the packaging box, the UAG mobile phone case gives people a solid feeling. You can feel its "reliable" side at the first touch. The internal TPU cushioning material protects the mobile phone shell from being scratched when it is disassembled, and the honeycomb structure reduces its weight while preventing falling.

In terms of appearance, the overall design style is tough, the design elements are biased towards the rack style, the shapes in different areas are concave and convex, and the transition of the dividing line is comfortable. Personally, I like its shape design very much.

The UAG mobile phone case fully wraps the buttons on both sides of the iPhone 14 Pro, which protects the buttons without dead ends. In order to facilitate the operation of pressing the key, a small opening is added in the key part, so that the key can be pressed with less force.

After the iPhone 14 Pro is worn, the volume of the UAG mobile phone is slightly increased, but for me with small hands, it can also be held very comfortably, achieving the coverage of all-hand users. The four corners of UAG are not designed at right angles like those of iPhone 14 Pro, but at oblique angles, which will not increase the cutting feel when held with one hand.

On the front of the mobile phone, UAG also has a unique screen edge protection function, which can increase the buffer on the front of the mobile phone to protect it when it falls. In addition, the opening of the UAG mobile phone case is very accurate and will not block the sensors and interfaces related to the mobile phone.

UAG mobile phone is also equipped with magnetic support, built-in 38 strong magnetic metal sheets, and supports MagSafe charging. While providing strong security, it also provides convenience.

Such a mobile phone case with strong protection and practicality is the best choice for iPhone 14 Pro series mobile phone cases.

The materials of mobile phone cases on the market are nothing more than common ones: silicone cases printed with various patterns, ultra-thin Kevlar cases and so on. Among the mobile phone cases I have used, one that impressed me deeply is a carbon fiber mobile phone case-Mero mobile phone case.

Carbon fiber has always given people the impression that it is light and strong. For example, many tripods made of carbon fiber are light and strong. This Mero carbon fiber phone case is no exception.

The back of the mobile phone case is made of carbon fiber woven structure, and the inside is designed with fluff, which can protect the mobile phone well and prevent scratching.

Mero carbon fiber mobile phone case adopts all-inclusive design, and the buttons on the side are wrapped in protective cases, which protects the mobile phone well.

At the same time, a semi-package design is adopted for mute key and lighting interface, which is convenient for operating keys and plugging and unplugging.

The overall fit of Muro carbon fiber mobile phone case is excellent, which can perfectly fit my iPhone 14 Pro. It feels comfortable to hold in the hand, and it has also been treated with corresponding anti-skid, which is just more anti-skid than bare-metal grip. In order to protect the camera, extra protrusions are also made on the outside of the camera.

As a light and practical carbon fiber mobile phone case, it is recommended to use.

I always travel by car during my daily commute, and the car bracket is one of the essential accessories. I have bought many car bracket products and stepped on many pits, among which the most satisfactory car bracket is PITAKA’s magnetic bracket. High value, heat dissipation and easy to use!

Accessories are simple, magnetic bracket, and a USB cable for power supply.

The back of the bracket is designed like a spherical tripod head, which can realize multi-angle rotation. The back is connected to the vehicle air outlet in the form of a hook, and the length of the hook can be adjusted by the knob at the back, which has been adapted to different vehicles.

PITAKA vehicle-mounted bracket has a small area after installation, and will not block the central control platform or other operation buttons at all. The charging cable attached with the product is also very convenient to store wires.

PITAKA’s official mobile phone case has a magnetic coil behind it, so it is very firmly attached to the car bracket, so you don’t have to worry about the phone falling due to the bumps on the road.

This iottie car bracket is also one of the first accessories purchased by my iPhone 14 Pro. It pays more attention to its novel form. Most of the car brackets are fixed on the vent of the car, and this bracket is fixed on the water cup holder.

There are not many accessories, only the bracket body and the cup base. You can install it well without reading the instructions.

Press the buttons on both sides of the bracket, and the bracket can be unfolded. After the phone is put down, press the silver piece on the front, and the bracket can be tightened to clamp the phone.

Put the cup base at the cup holder in the car and you can fix it. After actual installation, it will not affect other control units of the vehicle.

The iottie water cup bracket supports 90 adjustment, which is convenient for users to switch between vertical screen and horizontal screen. At the same time, with the 360 universal adjustment of the bracket, users can adjust the viewing angle more freely.

At the same time, the bracket is also equipped with the function of magnetic attraction line, which can more conveniently store the charging line.

If you want to find a compact car bracket to adapt to the iPhone 14 Pro, then this iottie air outlet car bracket must not be missed.

The vehicle-mounted bracket of the iottie air outlet can be firmly fixed in the air outlet through the plug at the rear, and the clip is made of hard rubber, which will not damage the air outlet.

The interior of the vehicle-mounted bracket of the iottie air outlet supports magnetic attraction, which is very firm after being connected with the iPhone 14 Pro, and supports 360-degree angle adjustment. It is a highly recommended vehicle-mounted bracket.

The above is the iPhone 14 Pro accessories I shared, and I hope it will help everyone! Later, I will bring you the iPhone 14 Pro experience, so stay tuned!

Author: Shen Chunlei

Ten academic papers (9 SCI and 1 new journal with high starting point) were published in 4 years, including 6 first authors and 4 co-authors. The total impact factor of SCI papers was about 93.

Liu Ying, a Ph.D. student at University of Science and Technology Beijing, has recently attracted a lot of attention due to this brilliant academic achievement.

At present, Liu Ying is studying in the Italian Institute of Technology, following Professor Liberato Manna, a big bull in chemistry and deputy editor of the internationally renowned journal Nano Letter. Liberato was ranked 24th in the ranking list of the top 100 cited chemists in the world published by Thomson Reuters from 2000 to 2010.

In March this year, Liu Ying will return to China and take part in the defense of doctoral thesis. Now he has received an offer from a key university in central China to directly hire a researcher. It can be said that Liu Ying has been ahead of her peers in the starting link of scientific research, so how did she do it?

Liu Ying is in Europe (Norway)

I would rather reread than change my major.

In September 2012, Liu Ying became a freshman at University of Science and Technology Beijing, majoring in industrial design.

When she first entered school, Liu Ying’s major courses were sketching and color, but she found that she didn’t like drawing very much. So, she came up with the idea of changing her major and put it into practice. In the first half of the freshman year, Liu Ying submitted an application to the school to transfer to the major of materials science and engineering, and finally passed the interview.

In September 2013, Liu Ying became a freshman again, majoring in materials science and engineering. Because of the great difference between the two subjects, she can only accept the price of changing her major-demotion.

However, Liu Ying is satisfied with his new major. Later facts also proved that she did the right thing in this multiple-choice question. During the undergraduate course, Liu Ying achieved excellent results and won many honors such as "People’s Scholarship" and "Three Good Students". In 2017, she obtained the qualification of insurance research in our school.

After changing majors, Liu Ying’s study is like a duck to water. In the first year of master’s degree, she applied for the qualification of master’s degree and doctoral degree.

Formal scientific research work has just begun. Liu Ying studied under Xia Zhiguo, a professor from the Department of Materials Physics and Chemistry, University of Science and Technology Beijing, mainly engaged in the synthesis and luminescent properties of inorganic perovskite nanocrystals.

She was shocked when she first saw with the naked eye that the synthesized nanocrystals showed bright green light. "The luminous efficiency of general materials is not so high."

Later, as the research on perovskite continued to heat up, Liu Ying began to carry out research on related luminescence fields around perovskite materials. In 2018, as co-first author, Liu Ying published an article entitled "Synergistic Preparation of High Stability/High Efficiency Perovskite Nanocrystals by Water Post-treatment Strategy" in Chemistry of Materials.

This is the first research paper related to perovskite published by Liu Ying. In 2018, Liu Ying published two papers as the first author and one as a co-author.

Two articles a year, writing quickly and correcting slowly is the trick.

From 2019 to 2021, Liu Ying published two papers every year.

Among them, Liu Ying’s most satisfactory paper was published in Angewante Chemie International Edition in 2020, which proposed a design idea of rare earth-doped lead-free perovskite nanocrystals, expanding its luminescent application.

Write quickly and change slowly, which is the paper writing skill summarized by Liu Ying. This article took about two weeks from the beginning of writing to the completion of the first draft, and it took about three to four weeks for the tutor to guide the revision of the paper. From the preliminary preparation to the final publication, it took about a year.

Liu Ying is very grateful to his tutor Xia Zhiguo and his research group. The tutor is very strict about the progress of scientific research, and the members of the research group need to submit weekly reports to the tutor to report their own experiments and work progress. The tutor asked the students to be good at finding and summarizing problems while ensuring the experimental time.

"A large number of experiments have accumulated to build a reasonable scientific framework for the paper, and then select appropriate journals to contribute according to the research field." In Liu Ying’s eyes, it is not difficult to send papers. Her tutor has always stressed that don’t send papers for the sake of sending papers, do more experiments, think and summarize more. In such an atmosphere, the quality and quantity of papers will not be bad.

"We are studying luminescent materials, and there are many scientific problems to be further discussed." Xia Zhiguo believes that publishing a paper is like selling your own research results, and only good results can get big sales.

He also asked students to go out more, participate in academic exchanges and integrate into the academic community as soon as possible. For example, Liu Ying’s article "Preparation of Perovskite Nanocrystals with High Stability/High Efficiency by Water Post-treatment Strategy" mentioned above was presented as an excellent poster paper at the Seventh National Academic Conference on Luminescence Properties of Doped Nanomaterials.

So, why did Liu Ying choose to study in Italy? It turns out that Liu Ying had previously cooperated with Liberato, and the research of Liberato’s research group is in line with her research on lead-free perovskite nanocrystals in China. So, she contacted Liberato, received an invitation letter, and later applied for a scholarship from the China government.

In February, 2021, Liu Ying officially went to Italy and began his one-year study and life.

I won’t stay in Beijing after graduation, but I will continue to do scientific research.

In China, Liu Ying will arrive at the laboratory before 8 am on weekdays, start work and leave the laboratory at 22 pm; In Italy, according to the working schedule of the research group, Liu Ying’s daily working hours were shortened by four hours. In her words, "When in Rome, do as the Romans do. If it is too early or too late, there will be no bus."

Compared with the pace of work and life in China, Liu Ying obviously felt much slower in this year. In a strange country and a brand-new environment, there will be some problems and many maladjustments. In the experiment, from synthesis to testing and calculation, the progress of each stage is very slow. What Liu Ying can do is to learn how to make rational use of time and plan his study life while slowly adapting.

Liu Ying is doing experiments in an Italian laboratory.

Talking about work and experiments, Liu Ying can always explain; When it comes to achievements and life, Liu Ying is a little shy.

Although Liu Ying rushed very hard in the initial stage of scientific research, she ran on the next way, hoping to advance at a constant speed. "I shouldn’t stay in Beijing after graduation. The work and life here are a little stressful for me." Liu Ying, who is about to return to China, is ready for her graduation. "I will settle in a second-tier city and continue my research in colleges and universities."

"I respect and firmly believe that my students’ choices are correct." As the tutor Xia Zhiguo said, "I hope students can continue to do scientific research and do what they like."

The 12-inch MacBook was an unexpected surprise at Apple’s spring conference. Many people are already eager to move, and they can’t wait to get rid of the MacBook Air at hand. Let’s first follow the foreign media to see how the new 12-inch MacBook performs.

The overall body of the 12-inch MacBook still adopts the classic wedge design on the Air, but the transition of the body is smoother. The thickest part is 13.1 mm and the weight is only 920 grams. From the data alone, it is difficult for us to intuitively feel how thin this product will be. The Verge reporter said after getting started that the 12-inch MacBook is much thinner than you think, and after the screen is turned on, the overall body will feel lighter.

In order to match the size of the whole machine, Apple redesigned the motherboard. The onboard memory jumped from 8GB, and the hard disk space was 256GB and 512GB. The workmanship of the whole machine is apple’s consistent standard, with a solid body and a solid feel.

However, there are two obvious changes in appearance besides thinness. One is that the Apple logo on the top of the fuselage is no longer the previous hollow light-transmitting design, but adopts a design similar to that on the iPhone and iPad. The second is that the 12-inch MacBook uses the same three colors as the iPhone, namely silver, gold and deep gray.

The redesigned keyboard adopts butterfly structure, the area of key cap is increased, the key spacing is shortened, but the key stroke is also shorter:

When typing on this keyboard, you will wonder if you are really typing. The overall input experience is similar to typing on a touch screen.

However, ArsTechnica’s evaluation of the keyboard is more conservative, thinking that as a writer who often deals with the keyboard, he has a strong subjective judgment on the keyboard. However, from the design point of view, the keyboard of the 12-inch MacBook seems to have a certain gap with the previous Mac products, but it does not rule out that after several days of use, the newly designed keyboard may change many people’s preconceived judgments.

For Apple’s newly designed Force Touch function, ArsTechnica said after getting started:

After pressing the touchpad, the built-in pressure feedback device will give a slight vibration. At the same time, the strength and sensitivity of feedback can be set in the system. This makes it very close to the traditional touch pad, and the only difference is that Force Touch can simulate the touch of pressing at any position on the touch pad.

In addition to the 3.5mm headphone jack on the right side of the fuselage, the USB-C interface on the left side has almost become the only outlet for data transmission inside and outside the 12-inch MacBook, which supports HDMI, VGA and Mini DisplayPort video output, and even shoulders the power supply for the notebook itself.

Paranoia, like Apple, will be so radical to adopt a single interface design. As mentioned in the previous 12-inch MacBook review article, such an advanced design requires a keen sense of smell and sufficient courage for new technologies, which is also in line with Apple’s consistent style. Previously, it was the first in the industry to abandon floppy drives, optical drives and mechanical hard disks.

Considering the need of fuselage expansion, Apple officially provided a multi-purpose adapter with a price of $79, which supports HDMI, standard USB and USB-C, and USB-C connects standard USB wires. What is certain is that in the future, Apple or third-party peripheral manufacturers will provide more types of patch cords.

Core M processors have appeared in many PC products. The 12-inch MacBook is also equipped with a 14nm Broadwell architecture Core M processor, which has two models, namely 1.1GHz (2.4GHz Turbo) Core M-5Y31 and 1.2GHz (2.9GHz Turbo) Core M-5Y71. According to ArsTechnica’s calculation, the performance of Core M is equivalent to that of Core i5 and i7 installed on MacBook Air in 2012. The biggest advantage of Core M lies in its excellent power control, with the highest power consumption of only 5W.

The 12-inch MacBook is equipped with a display screen with a resolution of 2304×1440, which is about 226ppi. Many people may have concerns about Core M driving such a high-resolution screen. ArsTechnica gives a comparison:

The GPU driving the first generation of 13-inch Retina MacBook Pro is the HD 4000 built in Ivy Bridge, while the HD 5300 graphics card is used on the 12-inch MacBook. It is not a problem to drive the screen with 2304×1440 resolution with its performance. There was no delay in the on-site demo, and the system animation effect of OS X was also very smooth.

Engadget also talked about the possible performance problems of the 12-inch MacBook when he started this new product, and thought that there were many good choices for Windows products at similar price points, such as the latest Dell XPS 13. The starting price of the 12-inch MacBook is 9288 RMB. Apple China official website has not given a clear delivery time yet, and the global delivery time is April 10th.

The comedy sci-fi movie Crazy Alien, directed by Ning Hao and starring super comedies Cass Bo Huang and Shen Teng, was officially released today. As the third part of the "Crazy Series" directed by Ning Hao, the film tells a cosmic absurd comedy story that happened in China. Shen Teng, Bo Huang, is pleasantly surprised, playing wits with the alien "Chica" skillfully, and the "grassroots counterattack" between the mysterious alien visitors and the ordinary people is expected. After the preview of the film was released, many netizens said, "I actually missed this immortal combination before", "Bo Huang and Shen Tengguang stood there and I wanted to laugh" and "I can’t see this lineup in the Spring Festival Evening now, but Bo Huang and Shen Teng must see it". Today, the film will return to the big screen to meet the audience, and an absurd and crazy journey of joy is about to appear. Let’s taste this "cosmic" hilarious story again and laugh together!

Bo Huang and Shen Teng join hands with aliens to go on a crazy trip. The "Circus" style poster is mysterious and eye-catching

The film surprises a poster released today, which depicts the crazy life of Bo Huang Shen Teng in a lively and grotesque circus style. Three striking colors, red, yellow and blue, are selected to collide in the color matching of the poster, which highlights the joyful and interesting overall style of the film. However, the two protagonists, Bo Huang and Shen Teng, sit side by side with scars on their faces and bandages on their heads. The seemingly stable mental state hides the "cry" that is about to break out, and the striking words on the poster are "2024 is tired, destroy it!" Echoing each other, we can’t help wondering what kind of crazy journey this pair of he is my brother has gone through. In addition, an alien’s hand is stretched out in the upper left corner of the poster, and the index finger seems to want to touch something, which seems to imply that the experiences of the two protagonists are related to the control of aliens. Many details revealed in the cheerful and contrasting poster attract the audience to go into the cinema to find out.

The film, starring Bo Huang and Shen Teng, can be called the "ceiling" of the "cosmic" comedy Cass. The "chemical reaction" produced by the combination of he is my brother played by the two people in the film makes netizens sigh that "I want to laugh when I stand there". In addition, the film also has a group of comedy comedians to join in the surprise, and Xú Zhēng specially starred in the foreign object "Chica" in the film; The appearance of Yu Hewei, Lei Jiayin and other national familiar actors makes people shine at the moment. The film was released in the Spring Festival in 2019, and became the mainland box office champion of comedy movies in 2019 with a box office of 2.213 billion. With the approach of 2025, the re-release of the film brings a happy atmosphere of "celebrating the New Year in advance" to the audience. After the release of the movie’s release, the audience sighed on social platforms, such as "I am looking forward to the release, and I feel that I will celebrate the New Year ahead of schedule when I see Bo Huang Shen Teng", "I missed the previous release, so I must make up this movie ticket this time" and "I want to brush it again", hoping to enter the theater again to witness the surprise combination of the two comedy masters. "Cosmic-level" super-card companies gathered together to stage a "Cosmic-level" joke suitable for decompression at the end of the year and open a comedy feast suitable for the whole family to watch movies!

Local elements and sci-fi themes surprise and collide, and the mental state is leading, making a year-end declaration for the current audience.

2024 is a special year. Looking back at the end of the year, it seems that history has come back once again. Many netizens exclaimed on social platforms that "I think it’s terrible, I seem to have traveled back to 2019" and "all this is too similar to 2019". The various details in the film are in one-to-one correspondence with the current reality. Shen Teng’s classic line "Destroy, Hurry, Tired" has once become a "high-frequency vocabulary" in recent years, and many viewers lamented that "the mental state of this film is really advanced, directly five years ahead of me" and "the original real prophet has already appeared". The film was released again at the end of 2024, and the advanced mental state of Bo Huang and Shen Teng, the two brothers, was also in line with the life creed that young people dare to say and go crazy, and became the "strongest excuse" for the declaration of contemporary young people at the end of the year.

As the third work of "Crazy Series" directed by Ning Hao, the film tells a hilarious sci-fi story with China local temperament. Geng Hao (Bo Huang) and Dafei (Shen Teng), brothers of "Niu Ma", who are struggling for their lives, accidentally meet Chica, a higher creature in the Milky Way, and encounter a series of incredible "mysterious forces", and stage a ridiculous journey. Geng Hao, played by Bo Huang, lives hard and insists on inheriting the intangible monkey drama, but it is despised. Dafei, played by Shen Teng, dreams of making a fortune, but has repeatedly fallen into the investment trap. The film also incorporates many traditional folk elements in China: intangible monkey drama, Chinese medicine massage, traditional opera, etc., which makes people feel strong Chinese local characteristics. Through the comedy expression of grounding gas, the film starts from the life of the little characters and blends into the unique Chinese fireworks. Under the surprise collision between the local and sci-fi, I hope to bring the audience a new experience of watching sci-fi movies.

The film Crazy Alien is directed by Ning Hao, starring Bo Huang and Shen Teng, and produced by Huanxi Media Group Co., Ltd., Bad Monkey Film and Beijing Light Film Co., Ltd. The film was released today, and an absurd and crazy hilarious journey was staged. Meet the audience and bid farewell to this year happily!

　　At 18: 00 on March 16, the Central Meteorological Observatory continued to issue blue rainstorm warning and strong convection warning, and issued blue blizzard warning, prompting the affected areas to continue to pay attention to early warning information, prevent disasters that may be caused by local heavy rainfall and strong convection, and do a good job of prevention.

　　The blue rainstorm warning shows that it is expected that there will be heavy rain in southern Henan, central and eastern Hubei, most of Anhui, most of Jiangsu, northwestern Zhejiang, northern and central Shanghai, northwestern Jiangxi, northern and southern Hunan, northeastern Yunnan and other places from 20: 00 on March 16th to 20: 00 on March 17th. Among them, there will be heavy rain in parts of southeastern Henan, central and southern Anhui and central and southern Jiangsu, and there will be heavy rain in southern Anhui (100-120 mm).

　　National forecast map of heavy rainfall area

　　Micro-science of meteorological disaster prevention

　　The blue warning of strong convection shows that from 20: 00 on March 16 to 20: 00 on March 17, there will be 8-10 thunderstorms or hail weather in parts of central and southern Anhui, central Jiangsu, eastern and southern Hubei, central and northern Hunan, northwestern Jiangxi, southern Sichuan, central and southern Guizhou, eastern Yunnan and northeastern Guangxi. There will be short-term heavy rainfall in parts of southern Henan, central and southern Anhui, central and southern Jiangsu, northern and eastern Hubei, Hunan, Jiangxi, western Zhejiang, western and northern Fujian, southeastern Sichuan Basin, southeastern and central Guizhou, northeastern Yunnan and northeastern Guangxi, with an hourly rainfall of 20-50 mm and a local area of more than 60 mm. It is estimated that the main impact period of strong convection is the night of 16th.

　　National forecast map of thunderstorm, gale or hail falling area

　What should I do if a strong convection comes?

　　The blue warning of blizzard showed that there was heavy snow (10 ~ 18 mm) in parts of south-central Inner Mongolia, northwestern Shanxi, northwestern Hebei and mountainous areas in northwestern Beijing from 20: 00 on March 16th to 20: 00 on March 17th. The depth of newly added snow in the above areas is 3 ~ 8 cm, and the local area can exceed 15 cm.

　　One of popular science reading:

　　How is the meteorological early warning information released?

　　Practice shows that early warning before disasters occur is the key to build the first line of defense for disaster prevention and mitigation. Early warning is not issued at will, it has experienced a life "four-part" of gestation, birth, spread and dissolution.

　　Pregnancy: data collection and analysis "brainstorming"

　　In order to find weather phenomena that may lead to disasters earlier, meteorologists monitor wind (wind, direction), temperature (air temperature, ground temperature, sea temperature), air pressure, humidity, visibility, rainfall (snow), lightning, clouds and many other meteorological elements around the clock.

　　All kinds of meteorological observation data collected are transmitted to the weather forecaster’s work platform and "fed" to the supercomputer. After calculation, a numerical value about the possibility of a meteorological disaster is obtained; According to the calculation results and all-round stereoscopic observation data, the weatherman analyzes weather charts and numerical forecast products at home and abroad, studies various types of weather charts, analyzes and judges the data obtained by various means such as meteorological satellites and radar detection data, and diagnoses the weather evolution; Compare the predicted value with the standard critical value of early warning level set in advance through research, and start issuing the corresponding type and level of meteorological warning when it meets the conditions.

　　At present, there are 14 kinds of meteorological disaster early warning in China, which correspond to blue, yellow, orange and red warning levels according to the development trend, urgency and harm degree of meteorological disasters.

　　Taking rainstorm as an example, issuing a blue rainstorm warning means that the precipitation will reach more than 50 mm in the next 12 hours, or it has reached more than 50 mm and the rainfall may continue; Issuing a red rainstorm warning means that the precipitation will reach more than 100 mm in the next three hours, or it has reached more than 100 mm and the rainfall may continue.

　　It should be noted that due to different regions, the impact of rainstorm warning at the same level will be different. For example, if 100 mm of rain falls in the rainy coastal areas of South China within 12 hours, the impact will of course be different compared with that in the less rainy northwest. Early warning signals shall be subject to those issued by the local meteorological department.　　

　　What do you think of rainstorm warning

　　Birth: the first authoritative voice

　　Every meteorological early warning information "released" must take a "only way", that is, the national early warning information release system.

　　As a part of the national emergency command platform system, the national emergency early warning information release system has set up four levels of early warning information release centers at the national, provincial, municipal and county levels. The public coverage of early warning has reached 87.3%, and the time limit for early warning release has reached 3 to 8 minutes. It can be targeted and sent to the disaster prevention responsible persons in the affected areas within 1 minute, and emergency response can be carried out quickly, making early warning signals truly the first line of defense for meteorological disaster prevention and mitigation.

　　Communication: Multi-channel timely response release

　　In order to improve the coverage of early warning information release as much as possible and realize rapid and accurate early warning information release, meteorological offices and stations affiliated to competent meteorological departments at all levels need to release early warning signals through various channels in time, indicate the areas for early warning of meteorological disasters, and notify the people’s governments at the corresponding levels, their relevant departments and disaster prevention and mitigation institutions.

　　Local people’s governments at all levels and their relevant departments should make a good connection plan after receiving the early warning signals provided by local meteorological stations, such as how the public security traffic police department manages road traffic and how the subway can prevent and deal with stagnant water. In addition, it should be widely disseminated to the public in a timely manner, and early warning signals should be disseminated in a timely manner through television, websites, mobile phones and other media, and the names of meteorological stations and stations that issued early warning signals and the release time should be marked.

　　From the "release" of meteorological early warning information to the affected people, the time left for people to take disaster prevention and avoidance measures is often only a few hours or even dozens of minutes. In this limited and precious time, whether the "last mile" of meteorological early warning information goes smoothly is directly related to the effectiveness of disaster prevention and mitigation.　　　

　　Release: Return to the Whole Chain Management of Disaster Prevention and Mitigation

　　After the release of meteorological early warning information, the weatherman should pay close attention to the development of disastrous weather, continuously observe the data that affect the early warning, and adjust the level of early warning in time. A blue warning may be upgraded to orange or red warning with the passage of time and the change of magnitude. When the disastrous weather process is over, the early warning cancellation message will be released, and the mission of early warning will be completed.

　　The second part of popular science reading:

　　What do you think of "blue, yellow, orange and red"?

　　In our daily life, we can often see meteorological disaster warning signals with different colors on our mobile phones and TV, and everyone is familiar with them. But when you think about it carefully, it doesn’t seem clear about the level of meteorological disasters, the impact and its defense methods represented by each color. Then, what should people do when they see the warning signal issued by the meteorological department?

　　look

　　At present, China has popularized a set of comprehensive methods for the release and dissemination of meteorological disaster warning signals, which consists of names, icons, standards and defense guidelines, and is divided into typhoon, rainstorm, blizzard, cold wave, gale, dust, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on. Warning signals of different colors indicate different levels. Generally speaking, there are four colors: blue, yellow, orange and red, which respectively correspond to the degree of harm, urgency and development trend that meteorological disasters may cause, and are Grade IV (general), Grade III (heavier), Grade II (serious) and Grade I (particularly serious).

　　Dichotomy

　　From blue, yellow to orange and red, the same kind of meteorological disaster warning signal has different levels, and the corresponding defense measures are also different. When the meteorological disaster warning signal is issued, the public should pay attention to the weather changes in time and make reasonable arrangements for travel. It should be noted that the categories and levels of meteorological disaster warning signals vary from place to place. For example, some areas will be affected by typhoons, while others will not. Some of the same categories are three-level "yellow orange red" and some are four-level "blue yellow orange red". This is because China’s geographical scope is vast, and the types and ranges affected by meteorological disasters vary from place to place. According to the characteristics of local meteorological disasters, provinces (autonomous regions and municipalities directly under the Central Government) can choose or add specified types of early warning signals and set different signal standards. But the same thing is that the higher the warning signal level of meteorological disasters, the more attention the public should pay.

　　Three actions

　　Generally speaking, we should pay attention to travel arrangements when we see the lowest warning signal. For example, when the blue rainstorm warning signal of the lowest level is issued, people should carefully consider the plans of traveling, going out for an outing or going to low-lying areas, and pay attention to the weather changes at any time. With the improvement of meteorological disaster warning signal level, people should make corresponding precautions, and must not "turn a blind eye" or "listen without hearing".

　　At the same time, we can refer to the Measures for the Release and Dissemination of Meteorological Disaster Early Warning Signals to further understand the meteorological disaster early warning signals and related preventive measures, and understand the meteorological disaster early warning signals through the official website of China Meteorological Bureau, Central Meteorological Observatory Network, China Weather Network and other channels. Schools, airports, ports, stations, highways, tourist attractions and other public places will also set up or use electronic display screens and other facilities to spread meteorological disaster warning signals.

　　In normal times, as long as we pay more attention to the weather and understand the meaning behind the warning signals of meteorological disasters, and don’t "underestimate the enemy" at critical moments, our awareness of prevention will be improved accordingly, and the effect of meteorological disaster prevention and mitigation will be greatly improved.

　　On the evening of May 10th, China successfully launched the Tianzhou-6 cargo spacecraft with the Long March 7 carrier rocket at Wenchang Space Launch Site. This is the first launch of China’s manned space engineering mission in 2023, and it is also the first flight mission in the application and development stage of China’s space station. What is the upgrade of this "Tianzhou Express"? What are the highlights of the launch mission?

　　Aspect 1: A new batch of cargo spacecraft is "launched"

　　On May 5, the Tianzhou-5 cargo spacecraft was successfully evacuated from the space station assembly and transferred to the independent flight stage. Today, China Space Station has welcomed new partners.

　　The Tianzhou-6 cargo spacecraft launched this time undertakes the tasks of material support, on-orbit support and space science experiments for the space station. Compared with Tianzhou-4 and Tianzhou-5 cargo spacecraft launched during the overall construction stage of the space station, Tianzhou-6 cargo spacecraft has an "extraordinary" identity — — The first spacecraft launched in the application and development stage of China’s manned space station; The first ship of China’s improved cargo spacecraft; The first cargo spacecraft produced in batches from Tianzhou 6 to Tianzhou 11.

　　As the ground logistics replenishment spacecraft of the space station, Tianzhou cargo spacecraft adopts the pattern spectrum scheme, and designs three types of patterns to meet different cargo transportation needs: fully sealed cargo spacecraft, semi-sealed cargo spacecraft and fully open cargo spacecraft.

　　Up to now, the cargo ships Tianzhou-1 to Tianzhou-6 are all developed by the Fifth Academy of Aerospace Science and Technology Group, among which Tianzhou-6 is an improved fully sealed cargo ship, which has the largest cargo transportation capacity and the most comprehensive on-orbit support capacity in the world.

　　In order to meet the demand of intensive launch, the Fifth Academy of Aerospace Science and Technology Group implements the batch production mode in the production process of Tianzhou cargo spacecraft, that is, Tianzhou No.3 to Tianzhou No.5 are produced and developed in batches, and Tianzhou No.6 to Tianzhou No.11 are produced and developed in batches, so as to ensure that the appearance and function of the same batch are similar or similar.

　　Since Tianzhou-6, the technical team has systematically upgraded the cargo spacecraft for the follow-up tasks, such as greatly improving the cargo cabin and greatly enhancing the cargo transportation capacity of the sealed cabin, so that the materials provided to the astronauts can last longer.

　　Aspect 2: Upgrade the strength of "bringing goods"

　　Tianzhou cargo spacecraft undertakes the mission of replenishing the propellant consumption of the space station and transporting the living materials of astronauts, which plays a very important role in the logistics support of the space station. In this mission, the Tianzhou-6 cargo spacecraft carried 258 pieces (sets) of cargo, with a total weight of about 5.8 tons, including six astronauts’ in-orbit consumables, about 700 kilograms of supplementary propellant and a number of actual (test) loads.

　　Yin Rui, senior engineer of China Astronaut Center and deputy commander-in-chief of astronaut system, said that the living materials of astronauts carried this time mainly include clothing, food, drinking water, etc. Among them, the fresh fruit weighs 71kg, which is about twice the weight of the fruit carried by Tianzhou No.5, which can meet the needs of Shenzhou 15 and Shenzhou 16.

　　A cargo ship, its "cargo" strength — — The strength of cargo loading capacity is the criterion of its "hard core". Therefore, how to effectively improve the cargo loading capacity has become the focus of the development of Tianzhou-6.

　　Entering the application and development stage of the space station, the cargo spacecraft system team of the Fifth Academy of Aerospace Science and Technology Group expanded the fully sealed cargo spacecraft into two States: standard 8 tanks and improved 4 tanks, which were selected according to the upward demand of the space station to add propellant.

　　The improved fully sealed cargo spacecraft expands the spectrum of the fully sealed cargo spacecraft, improves the cargo loading capacity of the sealed cabin, and can reduce the radio frequency of the cargo spacecraft from four in two years to three in two years, thus effectively improving the comprehensive benefits of the space station project.

　　The Tianzhou-6 cargo ship is an improved fully sealed state with four containers. Based on the Tianzhou-5 cargo ship, the original unsealed rear cone section is changed into a sealed cabin, so as to expand the loading space of the sealed cabin and improve the cargo ascending capacity of the sealed cabin. At the same time, the first floor tank was cancelled, and the equipment in the original rear cone section cabin was adjusted to the propulsion cabin.

　　After the improvement, the effective loading volume of the whole ship’s materials has expanded by 20%, and the loading capacity of the whole ship’s materials has increased to 7.4 tons, which is the first time that the cargo loading capacity of China’s cargo spacecraft has exceeded 7 tons.

　　Aspect 3: "old partner" speeds up and starts again.

　　The Long March 7 carrier rocket and Tianzhou cargo spacecraft, which have joined hands for six times, are already a pair of "old partners". The Long March 7 carrier rocket has become a "freight train" in the "transportation corridor between heaven and earth", which provides material support for the normal operation of China’s space station with the launch frequency of one or two times a year.

　　While achieving continuous success, the development team of the Long March 7 launch vehicle is also continuously optimizing the rocket design and launch site measurement and development process.

　　"In terms of the measurement and development process, this task has optimized the ground measurement and control software, and carried out single machine, system and full arrow verification, and the reliability of the measurement and development process has been further improved. At the same time, after process optimization, the launch time of the launch site was shortened from 27 days to 25 days. " Shao Yetao, chief designer of the Long March 7 launch vehicle of the First Academy of Aerospace Science and Technology Group, said.

　　Looking back, since the first mission of the Long March 7 carrier rocket, the time required for the launch site workflow has been reduced from 38 days to 25 days. Perhaps in the eyes of ordinary people, 13 days is not surprising, but for these 13 days, the Long March 7 carrier rocket model team has gone for nearly 7 years.

　　Compressing time is by no means a simple cancellation of processes and steps, but a further optimization of processes on the basis of thorough understanding of technology. Guo Jingang, deputy chief designer of the Long March 7 launch vehicle of the First Academy of Aerospace Science and Technology Group, said that in the past, the team used high-precision leveling instrument to measure the verticality of the rocket, and then the team took the factory platform and other facilities as reference, which ensured the "standing" safety of the rocket, simplified the operation items of the launch site, and contributed to the overall cost reduction and efficiency improvement of the rocket.

　　Zhou Hong, deputy director of the power system of the Long March 7 launch vehicle of the First Academy of Aerospace Science and Technology Group, introduced that the development team has improved the reliability of rocket engines and other products to further eliminate weak links.

　　Aspect 4: More scientific experiments will be carried out in the future.

　　The Tianzhou-6 cargo spacecraft not only carries various materials, but also carries a number of loads for scientific experiments and verification.

　　Lv Congmin, deputy chief engineer of the space application system of manned spaceflight project and researcher of the Space Application Center of Chinese Academy of Sciences, said that after the rapid rendezvous and docking of the Tianzhou-6 cargo spacecraft and the space station, the astronauts will transfer the related products to the space station cabin, and carry out 29 scientific experiments and application experiments in four fields according to the mission planning, including space life science and biotechnology, microgravity fluid physics and combustion science, space material science and new technology experiments of space application.

　　"We will carry out four scientific experiments, including the research on the influence of space microgravity environment on stem cell lineage differentiation, the research on the 3D growth and tissue construction of stem cells, the molecular evolution research on the co-origin of protein and nucleic acid and the origin of codon, and the biomechanical research on the influence of microgravity environment on cell interaction and cell growth." Lu Congmin said.

　　According to the plan, the experimental device for biological exposure of space radiation outside the Mengtian experimental module will be used to carry out research on key technologies of space radiation damage assessment science and application, tolerance of microorganisms in extreme environment to space exposure environment and its mechanism, and photochemical behavior of life molecules under space exposure environment.

　　Lu Congmin introduced that in the field of space application new technology test, the space environmental effect test of components and components such as large-scale integrated circuits, new semiconductor devices, optical fibers and optoelectronic devices will also be carried out by using the general test device for components and components outside the space of the space experiment module, which will provide technical support for the research and development of new components and components and the application and protection of space.

　　At noon on June 5th, 2020, chengdu research base of giant panda (hereinafter referred to as Panda Base) giant pandas "Yuanrun" and "Ellie" each gave birth to a female panda cub. The two cubs are very healthy and energetic, and they can both eat breast milk independently.

　　At 12: 32 noon, under the care of experts and breeders, the giant panda "Yuanrun" successfully gave birth to a female panda cub, with a birth weight of 172.6 grams and a very healthy body. "Yuanrun", who was upgraded to a mother, showed strong motherhood and quickly held her cub in her arms after birth.

　　At 13: 06 on the same day, the giant panda "Ellie" also successfully gave birth to a female panda cub, and the cub’s birth weight reached 219 grams, which was a "little fat man". After the cub was born, the mother "Ellie" immediately held it in her arms.

　　Experts from the Panda Base said: At present, the two giant panda babies and their mothers are in good health, and the breast milk supply is also very adequate. Among them, Ellie’s baby is the heaviest newborn panda cub since the panda base was recorded, reaching 219 grams, which is very energetic. She ate 6 grams of breast milk at birth, much higher than the average newborn panda baby’s food intake. (CCTV reporter Chen Kai)
