"Food security is ‘ The big country ’ " ;

　　"I have always been very concerned about grain production, and I often go to the fields to have a look when I do grassroots research";

　　"Never let others get stuck in our necks on the basic survival problem of eating";

　　"Ensuring the supply of primary products is a major strategic issue. Chinese’s rice bowl must be firmly in its own hands at all times, and the rice bowl is mainly filled with China grain";

　　… … … …

　　From the "granary" in Northeast China to the Loess Plateau, from the land of plenty to Bashan and Shushui, the General Secretary of the Supreme Leader is concerned about food security and agricultural enterprises. Going deep into the fields, carefully examining the growth of crops and crossing the footprints of mountains and rivers have condensed the general secretary’s deep concern for "China rice bowl".

　　The earnest warning of "firmly grasping the initiative of food security" has turned into a solid action of "grasping food production every year" In the past ten years, the vast number of agricultural enterprises have kept in mind the earnest entrustment, cherished the "country’s greatness", ploughed deep into the vast fields, and strived to safeguard national food security and explore agricultural modernization. In the past ten years, the vast number of agricultural enterprises have driven thousands of households and promoted the upgrading of the grain industry. The grain output has been stable at more than 1.3 trillion Jin for seven consecutive years and reached a new level of 100 billion Jin in 10 years. The secure "China Grain, China Rice Bowl" won the initiative to cope with various risks and challenges.

　　The rice bowl is served together and the responsibility is shouldered together.

　　"It is true at any time to have food in your hand and not panic in your heart."

　　"For a big country with a population of 1.4 billion, the basic position of agriculture cannot be ignored or weakened at any time. It is true at any time that there is food in hand and there is no panic in the heart."

　　General Secretary of the Supreme Leader, Yu Siwei, spoke of the importance of food security.

　　Three rivers rush, fertile fields stretch, and fertile fields are vertical and horizontal. Beidahuang Agricultural Reclamation Group Co., Ltd., which grew up in black land, is an important national commodity grain base and grain strategic reserve base with the largest cultivated land and the strongest comprehensive production capacity in China, and its annual grain output can meet the annual rations supply of 160 million urban and rural residents.

　　In September 2018, General Secretary of the Supreme Leader came to Heilongjiang Agricultural Reclamation Jiansanjiang Administration (now Jiansanjiang Branch of Beidahuang Agricultural Reclamation Group Co., Ltd.) for investigation and investigation. Seven-Star Farm’s 10,000-acre land is endless. The general secretary walked into the rice field and picked up a handful of rice ears to see the rice grains and the quality. General Secretary of the Supreme Leader said with emotion: "More than half a century has passed, and great changes have taken place in the Great Northern Wilderness. The development of mechanization, informationization and intelligence is remarkable, which is very inspiring and inspiring."

　　The farmer’s hand-held land guide who listened at the scene was full of emotions: "The general secretary cares about food from the bottom of his heart and cares about this black land!"

　　The general secretary’s deep concern, everyone keep in mind the heart, riveting enough energy to grow good food. The land guide said: "How to cultivate land efficiently and how to increase production, we study it wholeheartedly. Now there are satellites in the sky and ‘ Iron cow ’ ，‘ Cloud ’ There is still big data running in the park, and the black land is more energetic and the grain output is more stable. "

　　"Keep in mind the entrustment, strengthen the responsibility, stabilize the area, increase the production capacity, and ensure the supply, so that the Great Northern Wilderness will become a food security ‘ Big granary ’ 。” Wang Shoucong, Party Secretary and Chairman of Beidahuang Group, said. At present, the annual grain transfer volume of Beidahuang Group is stable at more than 40 billion Jin, and it has sold 1 trillion Jin of commercial grain for the country in the past 75 years.

　　Agricultural enterprises are duty-bound to stabilize the "China rice bowl". Since the 18th National Congress of the Communist Party of China, the vast number of agricultural enterprises have kept in mind the entrustment, given full play to their professional advantages, identified their roles, fulfilled their social responsibilities, and escorted food security.

　　Be brave in innovation and strive to be a new force in growing grain through science and technology.

　　Seeds are the key to China’s food security. On April 10th this year, General Secretary of the Supreme Leader stressed during his investigation in Yazhouwan Seed Laboratory, Sanya City, Hainan Province: "It is necessary to focus on ensuring food security and the supply of important agricultural products, and realize the self-reliance of seed industry in science and technology, and the independent control of seed sources, and use China seeds to ensure food security in China."

　　The light and heat in Hainan’s southern breeding base gave birth to new seeds. "The encouragement of the General Secretary has injected strong confidence into us to cultivate more China seeds." Every season in the south, Zhang Peng, a breeding expert of Syngenta Group under China Sinochem, appears in Tiantou on time like a migratory bird. "The team planted more than 20,000 breeding materials, tested and matched more than 5,000 combinations, and created more than 3,000 new breeding materials, just to find green and high-quality rice varieties." In 2021, Syngenta Group selected 180 excellent varieties.

　　"We always insist on writing the paper on black land, so that China grain can be planted in China." As the director of Jiansanjiang National Agricultural Science and Technology Park of Beidahuang Group, Li Xiaohui and his colleagues have been deeply involved in provenance research and development, improved seed breeding and other fields. The total area of high-quality rice has reached 31 million mu, and the average yield of rice has increased from less than 400 kg to 620 kg.

　　Enterprises are the main body of innovation and an important force to implement grain storage in technology. The vast number of agricultural enterprises aim at key links such as seed breeding, new product promotion and agronomic improvement, and carry out key research to insert scientific and technological wings for agriculture. At present, the contribution rate of agricultural science and technology progress in China has exceeded 61%.

　　Dare to take responsibility and strive to be a pathfinder for farmland protection.

　　"Farmland is farmland, and it must be fertile." Grain is stored in the ground, and the foundation of granaries in big countries is constantly consolidated.

　　"Three-dimensional planting, green circulation, let the soil eat ‘ Nutritional meal ’ The soil fertility has been restored. " Yang Yang, technical director of Zhongnong Chuangda (Beijing) Environmental Protection Technology Co., Ltd. said, "We have made breakthroughs in organic solid waste film composting technology and waste resource utilization carbon reduction and nitrogen fixation technology. The new technology can reduce the average chemical fertilizer per mu by more than 10% and increase the grain yield per mu by 5% to 10%. "

　　Restoring black soil fertility, improving saline-alkali land and building high-standard farmland … … Agricultural enterprises are everywhere. Aim at the weaknesses of the shortcomings, protect the ecology of cultivated land, and make every inch of cultivated land a fertile ground for harvest.

　　Accelerate the construction of a new agricultural management system

　　"Drive the vast number of small farmers to diversify and grow good grain"

　　In the rice fields, the green waves are churning and the seedlings are thriving.

　　"By agricultural machinery, we can not only farm, but also ‘ Hui ’ Farming. If you have an order, you will know that you can sell it at a good price when you plant it. Now farming is more promising. " Zhang Jinghui, a rice grower in Qixing Farm of Jiansanjiang Branch, said with emotion, "The grain harvest is much faster and better, and the income has been increased in recent years."

　　The new home with three bedrooms and one living room is spacious and bright, and the photo with the General Secretary of the Supreme Leader is hung in the most conspicuous position in the living room. Every time I recall the scene when the Supreme Leader General Secretary visited Qixing Farm, Zhang Jinghui felt warm and excited. "I reported to the General Secretary that my own rice has a brand and the sales are quite good. The general secretary nodded and said it was good. "

　　"Follow the farm and manage the land well, even how many holes are dug per square meter in the field and how many seedlings are inserted in each hole." Since September 2018, Zhang Jinghui’s brand rice sales have doubled.

　　Small farmers in big countries, "who will plant the land" and "how to plant the land", the general secretary of the supreme leader has a deep insight and a pulse.

　　"It is necessary to strengthen the popularization and application of modern agricultural science and technology and technical training, and organize large grain growers";

　　"Actively cultivate new agricultural business entities, develop and strengthen agricultural socialized service organizations, and encourage and support small farmers to take the road of development that combines with modern agriculture";

　　"I hope that large grain growers will give full play to the advantages of scale operation, actively apply modern agricultural science and technology, and drive the vast number of small farmers to diversify and grow good grain, and contribute to national food security together";

　　… … … …

　　Since the 18th National Congress of the Communist Party of China, the vast number of agricultural enterprises have kept in mind the entrustment of the General Secretary, given full play to the advantages of capital, technology and talents, and brought small farmers into modern agriculture, so that the vast number of farmers can truly take on the "golden pole".

　　Leading by the leader, the joint agriculture is strong.

　　As the agricultural "national team", agricultural reclamation enterprises have taken action. "Unified seed supply, unified prevention and control, unified harvesting, taking farmers into the market, more than 600,000 mu of cultivated land directly increased income by more than 130 million yuan per year." Ma Zhen Hui, the person in charge of Anhui Nongken Longkang Farm, said.

　　"Signed a trusteeship agreement with the Great Northern Wilderness, and we have big agricultural machinery for farming and harvesting, so I became a ‘ Shopkeeper of cutting ’ 。” Zhang Zhendong, a villager from Qianjin Village, Zhaoguang Town, Bei ‘an City, Heilongjiang Province, said. Beidahuang Group set up 10 regional agricultural service centers in Heilongjiang Province, and in 2021, it entrusted 10.8 million mu of land in the surrounding rural areas, increasing farmers’ income by 640 million yuan.

　　Leading enterprises and other new business entities are developing vigorously, giving full play to the role of linking agriculture with agriculture. By the end of 2021, there were more than 90,000 leading enterprises in agricultural industrialization at or above the county level, including 1,959 national key leading enterprises.

　　Interest connection, benefiting farmers and enriching farmers.

　　"When the new grain is listed, our daily purchase volume remains at around 400 tons, and the purchase price reaches 1.55 yuan." Li Quliang, general manager of Xinyuan Flour Co., Ltd., Jiaxiang County, Shandong Province, said, "The annual processing capacity of enterprises’ wheat is 130,000 tons, and more than 20,000 mu of wheat has been developed, driving more than 30 large growers."

　　Ordered grain and land trust … … More and more agricultural enterprises play a leading role and establish a close interest linkage mechanism. Leading enterprises pull, farmers’ cooperatives and family farms follow, and farmers participate. By the end of 2020, more than 7,000 industrialization consortia have been formed in China.

　　Turn the "big granary" into a "big kitchen"

　　"Building a modern agricultural base, large enterprises and large industries"

　　Say goodbye to the trouble of "being" and meet the challenge of "being good". The consumption upgrading of urban and rural residents requires both quantity and quality, and grain production is facing new challenges.

　　In May 2016, General Secretary of the Supreme Leader stressed during his investigation in Heilongjiang: "It is necessary to deepen the reform of the state-owned agricultural reclamation system and build a modern agricultural base, large enterprises and large industries."

　　Rice produced in black land has brought Daoxiang into thousands of households. Soybeans are transformed into soybean oil, soybean powder and other products and put on supermarket shelves. "The important speech of the General Secretary points out the direction for our work." Wang Shoucong said. Great Northern Wilderness Group optimizes varieties, improves quality, shapes brands, pays special attention to "the head of the grain eats the tail" and "the head of the farmer works the tail", and makes more "original brand names" become "new brand names".

　　"Now talking about food security is actually food security";

　　"On the basis of ensuring national food security, efforts should be made to optimize the industrial product structure";

　　"Give full play to its own advantages, seize the core competitiveness of grain, extend the grain industry chain, upgrade the value chain, build a supply chain, continuously improve the quality, efficiency and competitiveness of agriculture, and realize the unity of food security and modern efficient agriculture";

　　… … … …

　　After repeated investigations and important speeches, the General Secretary of the Supreme Leader drew a blueprint for the high-quality development of the grain industry and pointed out the direction.

　　Since the 18th National Congress of the Communist Party of China, "granaries" have been transformed into "kitchens". The vast number of agricultural enterprises are staring at the market to promote transformation, and the planting, marketing and sales are interlocking. The primary, secondary and tertiary industries are deeply integrated, so that the effective supply can keep up, the development of modern agriculture is fast, and new kinetic energy is strong.

　　Improve quality and supply more.

　　Polygonum cymosum wheat, full grain, bright color. "The yield per mu of new varieties has exceeded 800 kilograms for three consecutive years." Hou Yuanjiang, general manager of Shandong Qingfeng Seed Co., Ltd. said, "We have combined improved seed breeding with variety demonstration to drive more than 5,000 farmers in more than 30 villages to plant high-quality wheat, and the purchase price is 10% higher than the market."

　　The project of improving varieties, improving quality and high-quality grain has been carried out in depth. At present, 236 "China Good Grain and Oil" products have been selected nationwide, directly driving the increase of high-quality grain by more than 50 million tons.

　　Extend the chain and strengthen the chain, and connect the workshop in the field.

　　"Digesting about 110,000 tons of flour, about 60,000 tons of glutinous rice flour and about 20,000 tons of glutinous rice a year, researching and producing more than 500 varieties, and enriching the dining table for residents." Wang Peng, CEO of Missing Food, said. Today, 1/3 of instant noodles and 3/5 of glutinous rice balls are produced in Henan.

　　Looking at the whole country, in 2020, the grain industry will achieve an annual total industrial output value of 3.2 trillion yuan. Strong industry, safe food, high-quality development of food industry, mutual promotion of stable production and income increase, and promotion of national food security to a higher level.

　　Polish the brand and the market will be broader.

　　"Standardized and green production, polishing ‘ Yutai rice ’ Regional public brands let good rice sell at a good price. " Zhao Xinghua, Director of Agriculture and Rural Affairs Bureau of Yutai County, Shandong Province, introduced. At present, the county has developed 26,500 mu of high-quality characteristic rice.

　　More and more high-quality grain and oil brands are on the dining table of residents, constantly meeting diversified and personalized consumer demand. During the "Fourteenth Five-Year Plan" period, a number of leading grain enterprises and well-known grain and oil brands with market competitiveness will be formed throughout the country, and the increase of high-quality grain will increase by more than 10% annually.

　　The vast fields are full of vitality, and agricultural enterprises are bravely moving forward. On the new journey, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core and adhering to the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, the vast number of agricultural enterprises are making unremitting efforts and making new and greater contributions to stabilizing China’s rice bowl.

Foreword: Desperate for the strongest.

Lao Huang has a bad habit. The top graphics card on the desktop always needs to be castrated!

Both GTX 1080 Ti in Pascal’s era and RTX 2080 Ti in Turing’s era castrated 256 stream processors on the complete core. In the Ampere era, the top RTX 3090 also cut off 256 stream processors on the complete GA102 core.

Why does P.S. chop 256 stream processors every time?

Today, the rumored RTX 3090 Ti has finally been lifted. It is the first TITAN-level desktop graphics card that has not been castrated at the core for many years, and its positioning is 8K games and content creation!

However, even if the full version of GA102 has 10,752 stream processors, it is only 256 more than RTX 3090. Obviously, the 2% performance improvement is not enough to support Lao Huang’s ambition.

To this end, NVIDIA directly relaxed the TGP of RTX 3090 Ti to 450W W. With such horrible power consumption, its acceleration frequency was directly increased from 1695MHz of RTX 3090 to 1860MHz, a full increase of 165MHz.

Horrible 450W power consumption, complete 10,752 stream processors and abnormally high core frequency, it’s hard to imagine how far RTX 3090 Ti can reach!

This is the complete GA102 core, with 7 sets of GPC, 84 sets of SM units with a total of 10,752 stream processors, 112 ROP, 336 texture units, 336 third-generation Tensor Cores and 84 second-generation RT Cores. With 24GB GDDR6X memory, the memory frequency is 21GHz, the bit width is 384Bit, and the bandwidth is 1008 GB/s..

Although it is the same as RTX 3090 with 24GB GDDR6x video memory, the capacity of a single video memory is increased to 2GB, which means that there are only 12 video memories in total, all of which are placed on the front of PCB board. Compared with RTX 3090, the heat dissipation pressure of the video memory is reduced a lot.

The detailed specifications of RTX 3090 Ti are as follows:

As can be seen from the above table, the frequency and power consumption of RTX 3090 Ti have been horribly improved.

However, even if the power consumption is sharply increased to 450W, it is not easy to make GA102 run at such a high frequency! For this reason, NVIDIA had to choose the core with better physique to make it RTX 3090 Ti, and the lack of enough high-quality cores was one of the important reasons why RTX 3090 Ti was released until today.

Since RTX 3090 Ti has not been released in China, we used a RTX 3090 Ti PGF from Sotai in this first test.

Second, Sotai RTX 3090 Ti PGF picture appreciation: 8 ice pulse heat pipes+super large vapor chamber.

11 fan blades.

The brand-new 12+4Pin power supply interface is not compatible with any previous graphics card power supply interface, so you need to buy a matching power supply again.

Bottom view, the thickness is 63mm, the standard thickness of 3 grooves.

This should be the worst radiator ever piled by Sotai.

Eight ice vein composite heat pipes, a super-large area of vapor chamber and even a video memory are covered.

Feel the weight of the radiator.

Close-up of vapor chamber, covered with thermal pads.

It is to let the fan directly blow through the graphics card and improve the heat dissipation efficiency.

On the back of the PCB board, you can see that a part of the tail end is empty, in order to let the fan directly blow through the graphics card and improve the heat dissipation efficiency.

The PCB board looks big, but in fact, the main components are on the left.

RTX 3090Ti PGF OC is equipped with Sotheby’s S.E.P power supply system, 18+3 phase power supply circuit design, integrated DrMOS is used for power supply MosFET, and tantalum capacitor is used for power supply capacitor.

The front can’t fit, and some tantalum capacitors are placed on the back of PCB.

GA102-350-A1 core, 10,752 stream processors, with a core area of 628.4mm2 and 28.3 billion transistors.

Around the core is Meguiar’s GDDR6X video memory, with a total of 12, each with a capacity of 2GB and a total capacity of 24GB. The frequency is 21GHz, the bit width is 384Bit, and the memory bandwidth is 1008 GB/s.

This is different from RTX 3090, all the video memory is placed on the front, and the temperature of the video memory is easier to control.

Third, the test platform: TT TOUGHPOWER PF1 1250W white gold power supply.

The test platform is as follows:

I9-12900K processor.

ASUS ROG MAXIMUS Z690 HERO motherboard adopts 20+1 phase power supply circuit design, and each phase contains a 90A DrMOS, a ROG superalloy inductor and a 10K black gold capacitor.

Asustek’s control of processor voltage has reached a superb level. ROG MAXIMUS Z690 HERO motherboard can make i9-12900K and i5-12600K processors run stably at very low voltage. As for how low it is, we will talk about it later.

Chichi Ripjaws S5 flame blade DDR5 5200MHz 16GBx2 sleeve, frequency 5200MHz, time sequence 40-40-76, voltage 1.1V Gear 2 mode was used in the test.

Seagate Cool Play 2TB SSD, one of the strongest PCIe 4.0 SSD at present, the sequential reading and writing speed can reach 7000MB/s, and AS SSD runs easily over 12000.

Xingu Kunlun KL-360 ARGB water-cooled radiator adopts an exclusive separate water pump, and a 70mm PWM fan is embedded in the cold head, which can directly blow to the power supply circuit of the motherboard, which can reduce the VRM temperature by 12 degrees compared with the traditional water-cooled radiator.

Asus player country PG27UQ ROG 27-inch IPS esports display.

4K UHD(3840*2160) resolution, 4ms response time, 144Hz refresh rate, G-Sync technology, IPS+ quantum dot panel, 10bit color, and Display HDR1000 certification. It is still the top e-sports display on the market.

TT TOUGHPOWER PF1 1250W white gold medal power supply, fully modular design, single channel 12V output current 104A, 1248W output power.

8 graphics cards with 8 pins, 2 CPU/ graphics cards with 8 pins, 4 SATA 6PIN and 24Pin power sockets.

This is the 16-pin power cord, which needs to occupy two 8-pin sockets of graphics cards on the power supply, and the power supply is equivalent to 3x8Pin.

The test data are summarized as follows:

　

The goal of RTX 3090 Ti is 8K games, and then we didn’t have 8K monitors for the time being, so we only tested the results with 4K resolution.

At 4K resolution, the performance of Sotai RTX 3090 Ti PGF is 23% stronger than RTX 3080, 12% faster than RTX 3080 Ti and just 10% stronger than RTX 3090.

As for AMD’s RX 6900 XT, due to the limitation of 128MB Infinity Cache, its performance at 4K resolution is not satisfactory, and there is a 16% gap with RTX 3090 Ti.

If any students want to know the performance of RTX 3090 Ti PGF at 1080P resolution, here are the test results of "Survival of the Jedi" for your reference.

In Survival of the Jedi, RTX 3090 Ti is the first graphics card that broke through 400FPS.The average frame rate we tested was 402FPS, while the RTX 3090 was "only" 361FPS.

6. Temperature and overclocking test: The core temperature of the baking machine is only 70 degrees in half an hour.

1. Temperature test

Furmark was used to test the baking machine of Sotai RTX 3090 Ti PGF, and the test was that the room temperature was 24 degrees.

Furmark’s parameters are set to 1920*1080 resolution and 0AA. After running for 1 hour and 22 minutes, the temperature of RTX 3090 Ti is stable around 70 degrees, the temperature of Hot Spot is 80.3 degrees, and the memory temperature is only 76 degrees.The power consumption of the graphics card is stable around 450W W.

2, overclocking test

The Boost frequency of GeForce RTX 3090 Ti PGF is 1890MHz, which is 35MHz higher than that of the public version, and the TGP is as high as 450W, which is the same as that of the public version. There is still 45W overclocking space, and the maximum can be pulled to 495W by overclocking software.

After many attempts, RTX 3090 Ti PGF can pass all kinds of tests when the core frequency is increased by 110MHz, and the Boost frequency reaches the horrible 2000MHz；. GDDR6X video memory can also overclock to 21.9GHz, and the bandwidth of video memory is 1051gb/s.

After overclocking, the graphic score of 3DMark Fire Strike Ultra increased from 14,577, which was 623 points higher than 13,954 when the frequency was silent, and the increase range was about 4.5%. The highest operating frequency reaches 2160MHz. The highest power consumption reached 481 watts, and the highest temperature was only 66 degrees.

Seven, summary: the world’s strongest game graphics card!

The content of this test is briefly described as follows:

1. Performance

At 4K resolution, the performance of RTX 3090 Ti is just 10% faster than that of RTX 3090 and 23% faster than that of RTX 3080.

Compared with AMD’s flagship RX 6900 XT, RTX 3090 Ti is 16% faster than AMD. The reason for this problem is that 128MB Infinity Cache is difficult to cope with 4K resolution.

As for the resolution of 1080P, the performance of RTX 3090 Ti is also furious. It is the first graphics card that can run 400FPS in Survival of the Jedi, which is more than 10% faster than RTX 3090 and RX 6900 XT.

2. Power consumption

RTX 3090 Ti TGP up to 450W is really incredible. When running Wizard 3, the power consumption of the whole machine actually reached 600W, and when running Tomb Raider: Shadow, the power consumption was even close to 700W.

In addition, it should be noted that RTX 3090 Ti has replaced the 16-pin power supply interface, which is not compatible with the previous 8-pin and 12-pin interfaces. After buying a graphics card, you need to buy another power supply with 16Pin interface.

3, overclocking

Although the acceleration frequency of Sotai RTX 3090 Ti PGF has reached 1890MHz, it can exceed 110MHz on this basis, and finally the acceleration frequency reaches 2000MHz.

After overclocking, the performance of RTX 3090 Ti PGF can be improved by 4.5% again.

Let’s talk about Sotai RTX 3090 Ti PGF again!

As the king of stacking materials, Sotai equipped this graphics card with 21-phase S.E.P power supply system, integrated DrMOS and all-tantalum capacitor, which can easily provide 500W power.

In terms of heat dissipation, eight ice pulse composite heat pipes, three 90mm fans and super-large-scale vapor chamber can control the core temperature of GPU below 70 degrees under the state of 450W full load.

It may be hard to say whether the power consumption of 100W is worth 10% performance improvement!

But one thing is certain: if you buy this RTX 3090 Ti, you will have the strongest game graphics card in the world.

RTX 3090 Ti is the undisputed king of performance. Please refer to:

　　[car home Professional Test] With the increasing market share of new energy vehicles, the traditional fuel vehicles seem to be out of sight. Just like when a car needs to add more qualifiers to keep its sales number one, then its sales volume is really/seems/probably declining. However, for our protagonist Sylphy today, it is still the general trend. After all, at the moment when this fuel vehicle is not strong, it is really not easy for it, as the top seller of fuel vehicles, to still achieve sales of 374,500 units throughout the year.

★ Quickly understand the test results of 2023 Sylphy 1.6L:

◆ 0-100km/h acceleration time is 12.28 seconds;

◆ The braking performance of 100 km/h-0 is 39.88 meters;

◆ The measured fuel consumption is 7.11 L/100 km;

◆ The passing score of Elk is 72.9 km/h.

　　Although Nissan’s performance in 2023 was not satisfactory, and its annual sales volume was less than 700,000 units, Sylphy, as a bearer, sold 374,500 units, which is really the rhythm of a car to set off a brand. As a "very capable" player, what is Xuanyi’s real kung fu? Is it really just a flower shelf that is comfortable to sit on? I think the answer should be …….

■　This appearance is absolutely popular.

　　"I" is obviously Nissan. Why do you call me Volkswagen? Haha, don’t worry. I just said it looks like a Volkswagen fan. Indeed, in the market around 100,000 yuan, what everyone needs is a car that can take into account more usage scenarios. The more it can meet the needs of users, then it will certainly perform well in sales, and Sylphy just did it.

　　In this class of Sylphy, in fact, everyone’s size is not bad. Compared with Corolla and Bora, the data difference is very small, and everyone is basically the same.

　　After this change, the front grille part of the new Sylphy is further optimized, and the overall style is closer to the sound of nature, with a sense of sight. This has always been the usual design method of major manufacturers. The appearance of Sylphy, which was redesigned in the middle period, did not change much. As a real family car, the more it can meet the aesthetics of more people, then it must have positive significance for its sales growth. From the results of Sylphy’s sales crown of other fuel vehicles, everyone’s acceptance of it is still very high.

　　The interior part focuses on a warm home style. For example, the previously popular floating screen is also equipped. The combination of the three circular air conditioning outlets and the round bottom steering wheel can show its slightly sporty atmosphere. In addition, in terms of color matching, it provides all-black and black-brown color matching. In contrast, this black-brown color matching will have a stronger sense of warmth at home.

　　The performance in seating space is at the mainstream level of the same level, but the performance of Nissan’s seats in comfort is really good, and the soft seat filling better guarantees the comfort of long-term riding. However, the raised rear middle floor still has some influence on the comfort of the rear middle passengers when they are fully loaded, and it is more appropriate to use it occasionally in case of emergency.

　　Storage space, whether in the front row or the back row, is a sufficient level. The volume of the trunk needs to be emphasized. Take the 1.6L fuel version we tested this time as an example. Its trunk volume actually reached 560L, which is really too large, even larger than the trunk of Mercedes-Benz S. Can you stand it?

■　Power 1.6L+CVT

　　At present, Sylphy on sale includes Sylphy, Classic Sylphy and Sylphy’s ultra-hybrid electric drive, which is the familiar e-POWER extended range system. Sylphy and Classic Sylphy are both equipped with 1.6L engines, with maximum power of 135 and 122 horsepower, respectively, and peak torque of 159 and 155 Nm, which match Nissan’s traditional CVT gearbox. On the other hand, the extended-range vehicle uses a three-cylinder 1.2L engine as the range extender. The power of the driving motor is 136 HP and the peak torque is 300 Nm. The transmission system is matched with a single-gear fixed gear ratio gearbox.

　　Sylphy has always given us a comfortable impression, and this generation of cars is no exception. The curb weight of less than 1.3 tons makes this 1.6L engine very light to drag, especially at the start and at low and medium speeds. The linear power output of the 1.6L engine makes you more comfortable when walking around the city in daily life.

　　Some people will say that its 1.6L power is a little weak, and it really lacks a little passion compared with those 1.5T power models on competing products. This is understandable, but Sylphy’s e-POWER model can fill this part of the shortcomings well. The extended-range power system feels similar to a pure tram when driving most of the time, and its power performance is sufficient and direct.

　　Back to our Sylphy with 1.6L+CVT power, the smoothness of the gearbox is obvious to all. The characteristics of CVT gearbox and Nissan’s experience in adjustment for so many years make us have enough confidence in this power. In daily driving, its sense of participation is very low, and its ride comfort is worthy of recognition. In addition, the lighter steering is another factor that makes driving easy. We often say that the electronic smell of the car is getting stronger and stronger, and it lacks a little mechanical sense. But for the car with home positioning, it really needs more electronic assistance, light power and the power is not strong but linear after the accelerator is stepped on. Isn’t this the feeling that most people need in daily driving?

　　In the noise part, it is necessary to emphasize that when driving at medium and high speed, the whole noise is too large, and the NVH of the whole vehicle still has room for improvement in suppressing wind noise and road noise.

■　All AEB tests passed within 60 km/h.

　　The intelligent driving version we tested is equipped with L2 driver assistance function, and then we will take a look at its test results in this part. It’s 4,000 yuan more expensive than the Enjoyable version with a lower configuration, and I think the extra driver assistance system is fully worth the price difference.

　　Let’s first take a look at two common working conditions of AEB in the face of children’s ghost probes and mobile electric motorcycles, which are very common in our daily urban vehicles. This Sylphy version of the car has performed well in these two projects. Vehicles can detect moving objects in time, make sound reminders in the car, and brake the vehicles in time to avoid collisions. The calibration of this AEB system is mature, and the whole braking action at work is natural, which can be praised.

　　In the AEB test, we passed the tests of 10km/h, 20km/h, 30km/h, 40km/h, 50km/h and 60km/h respectively, and with the increase of vehicle speed, the braking advance will increase linearly, and the system will feel more natural when braking, which can effectively reduce the occurrence of rear-end collision accidents in daily cities at low speed. However, collisions cannot be avoided at higher speeds, so you should pay more attention when driving.

　　In terms of midway acceleration performance, its 40-80km/h is 5.9 seconds, and 80-120km/h is 8.47 seconds. From this performance alone, it is really too domestic. In the whole accelerated testing process, it is surprisingly smooth, basically without any sense of pushing back, and the final result is naturally more ordinary.

　　In the tests of acceleration, braking, braking, elk and fuel consumption, most of the results of this 1.6L Sylphy are expected, but its fuel consumption is actually slightly higher than we expected. In addition to the home market, Sylphy also has a certain share in the travel market. Compared with those plug-in models, this fuel consumption performance has not been opened in terms of price and fuel consumption performance.

Summary:

　　In 1959, Nissan introduced the first generation of Sylphy, and in 2006, the 12th generation model began to enter China, and the cumulative sales reached 300W+. As the most successful model of Nissan in China, Sylphy is also one of the first choices among many family cars. On the whole, it is still a car with balanced comprehensive performance, regardless of its shape, configuration or driving assistance. In terms of sales volume, the more affordable classic Sylphy is also contributing to its own strength, while the e-POWER model has a good balance between power and energy consumption, and a variety of optional models are also its competitiveness. So on the whole, when we choose a compact family car, it is still the one that will be included in the alternative list. (Text/Figure car home Dong Liu)

　　Recently, annual economic reports have been published in various places, and the data of 15 new first-tier cities in 2020 have been announced.

　　By combing the GDP data of 15 new first-tier cities in 2020, CBN found that 13 of the 15 cities have exceeded the trillion-dollar mark. Among them, Chongqing and Suzhou exceeded 2 trillion yuan, closely following the first-tier cities. Xi ‘an ranks first in the growth rate of new first-tier cities.

　　According to the Business Charm Ranking of Cities in 2020 released by CBN New First-tier Cities Research Institute in June 2020, the 15 new first-tier cities in 2020 are Chengdu, Chongqing, Hangzhou, Wuhan, Xi ‘an, Tianjin, Suzhou, Nanjing, Zhengzhou, Changsha, Dongguan, Shenyang, Qingdao, Hefei and Foshan.

　　Catch up with first-tier cities, Chongqing and Suzhou exceed 2 trillion.

　　The data shows that in 2020, the total GDP of 15 new first-tier cities reached 20,716.422 billion yuan, accounting for 20.4% of the country.

　　Among the 15 cities, 13 cities have GDP exceeding the trillion yuan mark, and 2 cities have GDP exceeding 2 trillion yuan, namely Chongqing and Suzhou. Among them, Chongqing ranks first in the new first-tier cities with 2500.279 billion yuan. Among all the cities in China, Chongqing’s GDP ranks fifth after Shanghai, Beijing, Shenzhen and Guangzhou.

　　In 2020, the total GDP of Chongqing is only 1.632 billion yuan less than that of Guangzhou, the fourth first-tier city. In the future, the total GDP of Chongqing is likely to surpass Guangzhou and enter the top four ranks.

　　At present, Chongqing is still accelerating the pace of industrialization and urbanization. The data shows that in 2020, the added value of industrial enterprises above designated size in Chongqing increased by 5.8% over the previous year. In terms of three categories, the added value of mining industry decreased by 0.6% over the previous year, manufacturing industry increased by 6.4%, and electricity, heat, gas and water production and supply industries increased by 2.1%. The eight pillar industries continued to recover, and the automobile, electronics and materials industries greatly promoted the industrial growth of the city, with the added value increasing by 10.1%, 13.9% and 7.1% respectively over the previous year. Equipment, medicine, consumer goods industry and energy industry increased by 2.9%, 4.5%, 0.8% and 0.9% respectively.

　　Peng Peng, executive chairman of Guangdong Provincial System Reform Research Association, analyzed the First Financial Report. Chongqing’s population and geographical area are much larger than those of Guangzhou. Under the new development pattern of double circulation, its advantages will be more obvious. In addition, the huge population will be transferred to cities and towns, which will have a great pulling effect on infrastructure construction and real estate. There is a high probability that the total GDP will surpass Guangzhou in the future.

　　After Chongqing, Suzhou’s GDP in 2020 was 2,017.05 billion yuan, an increase of 3.4% over the previous year at comparable prices. The total GDP ranked second among new first-tier cities and sixth among all cities in China. It is worth noting that Suzhou is also the only ordinary prefecture-level city among the six cities that have broken through the 2 trillion yuan mark, and is also known as the "most cattle prefecture-level city".

　　Data show that last year, Suzhou achieved a general public budget revenue of 230.3 billion yuan, an increase of 3.7% over the previous year, making it the fourth largest city in China for the first time. There were 29 new domestic and overseas listed companies, including 25 domestic A-share listed companies. There are 181 listed companies at home and abroad, including 144 domestic A-share listed companies, ranking fifth in the country.

　　Ding Changfa, an associate professor in the Department of Economics of Xiamen University, analyzed the First Financial Report. Suzhou is backed by Shanghai, "enjoying the cool under a big tree", and the spillover effect of Shanghai is particularly obvious. Strong scientific and educational resources and modern service industries have promoted the transformation and upgrading of Suzhou.

　　The data shows that in 2020, the number of high-tech enterprises declared, recognized, net increased and effective in Suzhou reached a record high. At the end of the year, the number of effective high-tech enterprises reached 9,772, approaching 10,000, continuing to rank fifth in the country, second only to the four first-tier cities in Guangzhou, Guangzhou and Shenzhen.

　　Chengdu’s GDP ranks third in new first-tier cities with 1.77 trillion yuan. In recent years, Chengdu’s high-tech industry has developed rapidly. According to previous reports from Chengdu media, in 2020, it is estimated that there will be more than 1,900 high-tech enterprises in Chengdu, with an increase of over 40%, and the total number is expected to exceed 6,100. At the same time, it is estimated that the annual revenue of high-tech industries will exceed 1 trillion yuan.

　　The fourth place is Hangzhou. After the epidemic, Hangzhou’s digital economy has accelerated its development and the inflow of talents has accelerated. According to the data of Hangzhou Municipal Bureau of Statistics, in 2020, the added value of the core industries of digital economy in the city was 429 billion yuan, up 13.3%, 9.4 percentage points higher than the GDP growth rate, accounting for 26.6% of GDP, up 1.9 percentage points from the previous year; The added value of digital content, software and information services, and electronic information products manufacturing industries were 311.3 billion yuan, 344.1 billion yuan and 109 billion yuan, respectively, up by 12.7%, 12.9% and 14.7%. The artificial intelligence industry continued to grow, achieving an added value of 34 billion yuan, an increase of 8.2%.

　　This year’s work report of the Hangzhou Municipal Government shows that in 2020, the attraction of Hangzhou to outstanding talents will continue to increase. In 2020, Hangzhou introduced 436,000 college students under the age of 35, and the net inflow rate of talents continued to rank first in the country.

　　13 cities exceed one trillion, and Dongguan has a foot in the door.

　　Wuhan, which was most affected by the epidemic, saw its GDP decrease by 4.7% in 2020, ranking fifth after Hangzhou in the new first-tier cities.

　　Nanjing is a typical example of the rise of a strong province in recent years. As one of the five largest cities with the most concentrated higher education resources in China, Nanjing ranks third in the country in terms of comprehensive strength in science and education, second only to Beijing and Shanghai, and has many powerful universities such as Nanjing University and Southeast University. In recent years, Nanjing has given full play to its strong advantages in science and education resources, vigorously built a famous science and technology city and developed emerging industries. In 2020, the total GDP of Nanjing will enter the top ten for the first time among all cities.

　　Despite being surpassed by Nanjing, Tianjin’s GDP in 2020 also exceeded 1.4 trillion yuan, which is not far from Nanjing. Qingdao, Changsha and Zhengzhou all exceed 1.2 trillion yuan, and the gap between them is also very tight.

　　As a manufacturing city, Foshan entered the trillion-dollar mark in 2019, and continued to relegate successfully in 2020, staying in the trillion-dollar club. Hefei and Xi ‘an, two cities with strong provinces, entered the ranks of trillion clubs for the first time in 2020. Among them, Xi ‘an became the first trillion-dollar city in the northwest.

　　Together with Hefei and Xi ‘an, among the 15 new first-tier cities in 2020, 13 cities have already entered the trillion-dollar club, and only Dongguan and Shenyang have not yet been shortlisted. Among them, Dongguan, as an important reserve army of a trillion-dollar club city, was temporarily stranded in 2020.

　　Hu Gang, president of South China Urban Research Association and professor of Jinan University, analyzed CBN, and found that Dongguan will be greatly impacted by the export-oriented economy in 2020. Affected by the epidemic, a large number of migrant workers found it difficult to return to their posts in the first quarter of 2020, and many orders could not be completed; After April, the export was blocked again. However, with the rebound of orders, according to the current situation, Dongguan will have a high probability of breaking through the trillion-dollar mark in 2021.

　　In contrast, Shenyang, the only new first-tier city in Northeast China, is still far from the trillion-dollar mark. According to the data released by Shenyang Municipal Bureau of Statistics, the city’s GDP in 2020 is 657.16 billion yuan, which is 0.8% higher than the previous year at comparable prices, and the total economic output is only 26.3% of that of Chongqing, which ranks first.

　　From the perspective of growth rate, several new first-tier cities with faster growth rate are mainly cities with strong provinces, among which the top five are Xi ‘an, Nanjing, Hefei, Chengdu and Changsha. Among them, Xi ‘an ranks first in the new first-tier cities with a growth rate of 5.2%. In addition, Hefei, Changsha and Chengdu also come from the central and western regions.

　　Ding Changfa told CBN that with the rise of comprehensive costs in coastal developed areas, a large number of industries moved to the central and western regions. In this process, the central and western regions, especially the cities with strong provinces, became the focus of industrial and population agglomeration, and the economic growth rate was relatively fast.

　　On the other hand, after China’s economic development has entered a new stage of transformation and upgrading, the advantages of provincial capital cities in science, education, medical care and culture have become increasingly prominent, the development of high-tech industries in provincial capital cities has accelerated, the city’s primacy has also been continuously improved, and the ability to gather surrounding resource elements and drive and lead the surrounding development has been continuously enhanced.

　　In contrast, the cities with slow growth rate, except Wuhan, which was hit hard by the epidemic, are mainly from Northeast China and North China, and Dongguan and Foshan, where the coastal export-oriented economy accounts for a relatively large proportion.
