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.

　　Xinhua News Agency, Wenchang, Hainan, May 10 th: Four highlights of the launch of Tianzhou-6

　　Xinhua News Agency "Xinhua Viewpoint" reporters Song Chen, Li Guoli and Chen Kaizi

　　The effective loading capacity of the whole ship’s materials has been expanded by 20%, and the strength of "carrying goods" has been upgraded; The Long March 7 carrier rocket and Tianzhou cargo spacecraft joined hands for six times, further shortening the test time and further improving the reliability of the process; We will focus on the fields of space life science and biotechnology, and carry out 29 scientific experiments and application experiments … …

　　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.

　　On May 7, the combination of Tianzhou-6 cargo spacecraft and Long March-7 remote-7 carrier rocket was ready for transshipment. Xinhua News Agency (photo by Qiu Lijun)

　　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)

　　CCTV News:As of today (December 28th), the West-to-East Gas Pipeline Project, with a total investment of more than 400 billion yuan and continuous construction for 20 years, has become one of the largest natural gas pipeline systems in the world. Let’s review the development history of engineering in this century.

　　In February, 2000, the country started the West-to-East Gas Transmission Project, which was regarded as a landmark project for the development of western China.

　　On July 4, 2002, the West-to-East Gas Pipeline Project started. On December 30, 2004, the first line of west-to-east gas transmission was put into commercial operation. The first line of west-to-east gas transmission takes Tarim gas field in Xinjiang as the main gas source and the Yangtze River Delta as the main target market.

　　With the increasing demand for natural gas clean energy in the downstream market, the west-to-east gas transmission project was started in March 2005, and the gas transmission capacity was increased by more than 40%. In 2007, the Second West-to-East Gas Pipeline Project was officially launched, and it was put into operation in 2011, transporting natural gas from the Central Asian natural gas pipeline to the central and southern parts of China and the Pearl River Delta region.

　　Since the 18th National Congress of the Communist Party of China, the construction of the West-East Gas Pipeline has been further accelerated. In 2012, the Third West-East Gas Pipeline Project started construction, and fully realized the autonomy of engineering technology and the localization of technical equipment. After completion, it was connected with the original first and second lines, realizing the leap-forward development from pipeline gas transmission to pipeline network gas transmission.

　　This year, the middle section of the third line of west-to-east gas transmission started construction. The annual gas transmission capacity of the west-to-east gas pipeline system has exceeded 100 billion cubic meters, a record high.
