Ding ~ the oil circle "fragrance" is coming!

March vegetables bloom,

Rapeseed is ripe in June,

Seed oil pressed in August.

After four seasons of sowing in autumn, storing in winter, growing in spring and harvesting in summer, a grain of rapeseed has matured, and through the processes of removing impurities, frying seeds, squeezing, filtering and settling, clear, transparent and mellow rapeseed has entered thousands of households.

Everyone has appreciated the beauty of rape blossoms and tasted the fragrance brought by rapeseed oil, so how much do you know about rapeseed oil? Today, small farmers invited Hu Qiong, a researcher from the Institute of Oilseed Crops, Chinese Academy of Agricultural Sciences, to listen to experts talk about rapeseed oil!

The name of rape

At the end of the Eastern Han Dynasty, Fu Qian wrote "Popular Wen", which recorded that "Brassica is called Hu Cai", and "Brassica" was the ancient rape in China, which was often used as a vegetable at that time.

Later, people gradually discovered that rape seeds can produce oil, so they bred Chinese cabbage rape which can extract oil through breeding and domestication. Rapeseed is also named after "oil".

How rapeseed becomes vegetable oil

picture

Generally speaking, rapeseed oil extraction technology can be divided into "pressing" and "extraction".

"Squeezing" is the physical and mechanical squeezing of rapeseed by using squeezing equipment to produce oil, which can be divided into cold pressing and hot pressing, among which hot pressing is more commonly used.

"Hot pressing" means that rapeseed is heated by frying, steaming, etc., and then mechanically pressed to produce oil; "Cold pressing" means that rapeseed is pressed without baking or slightly heating, and the "crude oil" squeezed by cold pressing needs heating and dehydration before it can be filtered out into clear vegetable oil.

In contrast, hot pickled mustard tuber oil is rich in flavor because of the influence of high temperature; Cold mustard tuber oil is clear and beautiful in color, but light in fragrance.

"Extraction" is to soak or spray rapeseed with an organic solvent that can dissolve oil, so that the oil in the oil can be extracted.

In addition, it is popular to extract vegetable oil by "microwave pressing" on the market at present. This method uses microwave to heat rapeseed, which can better control the temperature and make the color of oil clear. At the same time, it is also conducive to the efficient release and dissolution of nutrients and oils in rapeseed, and plays a certain role in enhancing fragrance.

N reasons for choosing vegetable oil

In general, three kinds of rapeseed, Chinese cabbage rape, cabbage rape and mustard rape, can be used for oil extraction. However, because of the strong disease resistance and good quality of Brassica napus, most of them belong to double-low varieties (low erucic acid and glucosinolate content) and high oil yield, so they are mostly selected for oil extraction.

      Fatty acid composition balance: the fatty acid composition in rapeseed oil is relatively balanced, and the saturated fatty acid content in vegetable oil is the lowest, about 7%.

High oleic acid content: It is pointed out in the Dietary Guide for China Residents that oleic acid can reduce bad cholesterol and increase good cholesterol. In the eyes of experts, oleic acid is also an important indicator to measure whether an edible oil is more conducive to health. At present, the oleic acid content of most vegetable oils sold in the market can reach 60%, and the oleic acid content of rapeseed oil with high content can even reach more than 70%, which can well meet the public’s demand for oleic acid.

picture

Reasonable ratio of linoleic acid to linolenic acid: According to the Standard for Healthy Edible Oil issued by FAO, the ratio of linoleic acid to linolenic acid in essential fatty acids should be less than or equal to 4:1. Linoleic acid and linolenic acid are one kind of unsaturated fatty acids, which cannot be synthesized by human body. The proportion of rapeseed oil is reasonable.

Rich in nutrients: Rapeseed oil also contains major trace elements needed by human body, such as iron, copper and zinc, and the proportion of vitamin E in rapeseed oil is relatively appropriate.

Rapeseed oil is currently recognized as "the healthiest edible vegetable oil for the public".

What is unique about "low erucic acid vegetable oil"

"Low erucic acid rapeseed oil" refers to rapeseed oil with erucic acid content not exceeding 3%. It is made by squeezing low erucic acid rapeseed, and the erucic acid content is much lower than that of traditional rapeseed oil.

At present, the United Nations Food and Agriculture Organization (FAO) and WHO have put forward a limited standard for erucic acid in edible oil, requiring that the erucic acid content in edible oil should be less than 5%. The standard of erucic acid content in edible oil in some countries requires that it should not exceed 2% of total fatty acids.

picture

In the chemical molecular composition of oleic acid and linolenic acid, the carbon chain is short, while erucic acid is a long-chain unsaturated fatty acid, which consists of 22 carbon chains. The long carbon chain is difficult to digest and has poor absorption and utilization rate, which will reduce the nutritional value of vegetable oil. And high doses of erucic acid can also induce myocardial fat accumulation, congestive heart failure and other diseases.

Now, the vegetable oil brands advertised as "low erucic acid rapeseed oil" in Shangchao and grain and oil stores are generally up to standard in erucic acid content, so you can buy them with confidence.

Tips for eating vegetable oil

No.1: which onesPeople are not fit to eat vegetable oil?

Rapeseed oil is suitable for all ages. Under normal circumstances, as long as there is no allergic reaction to the ingredients of rapeseed oil, most people are suitable for eating rapeseed oil.

However, in view of acute gastroenteritis, diarrhea and other diseases, it is suggested to control the dosage of vegetable oil. Although there is an old saying that "too much oil will not spoil vegetables", it is important to remember that too much oil will spoil people, so it is not advisable to drink too much cooking oil every day, just in moderation.

No.2: how to preserve the vegetable oil after opening?

It is recommended to keep it away from light and heat. Rapeseed oil after daily opening can be stored in a glass bottle for sealing, away from the stove, and placed in a dark cabinet, so as to avoid the emission of effective components in the rapeseed oil and not affect the fragrance and taste of the oil.

No.3: what is the best way to eat vegetable oil?

The content of unstable fatty acids in rapeseed oil is less, so it will not form too many trans fatty acids harmful to human body after heating, and high-temperature cooking can release the fragrance of rapeseed oil well and enrich the taste of vegetables.

Rapeseed oil is listed as the first choice for making Chili oil because of its strong fragrance, bright oil and high temperature resistance. Stir-frying rapeseed oil and pepper at high temperature can effectively blend their unique flavors and increase the overall flavor of Chili oil.

If it is high oleic rapeseed oil, its stability is better. Compared with other types of vegetable oil, it can withstand high temperature heating and repeated frying. Suitable for making fried food, such as fried dough sticks, French fries and other foods.

In addition, the fragrance of normal temperature rapeseed oil itself is not as rich as sesame oil, and if it is used to mix cold dishes without heating, it may not taste particularly good. Therefore, if the heated vegetable oil is used to mix cold dishes, the oil fragrance will be more obvious.

Food is the most important thing for the people.

Courier is under increasing pressure. Can intelligent courier cabinet solve the problem of courier industry?

       The emergence of intelligent express cabinets can provide users with 24-hour self-service pick-up service, which seems to effectively solve the "last mile" problem. In just a few years, the smart express cabinet industry is competing with each other and capital is swarming. Relevant experts remind: to solve the problem of unclear business model.

  "I didn’t expect that the things I bought in Taobao could actually be picked up by the rookie in Paris!" Li Qian, a French student studying in Chongqing, told reporters on October 17th that you can get it by entering the pick-up code, and the location is not far from your residence, so you can get it on the way back to your dormitory after class. Many foreign students said yes.

  In September this year, the first batch of express cabinets set up by rookie in Paris, the French capital, was officially opened, with a total of 60 groups, which were mainly set up in the local core business district and scenic spots. Foreigners realized the freedom to pick up their pieces by relying on the express cabinets in China.

  In recent years, the emergence of intelligent express cabinets has solved the pain points of mismatched delivery time, low efficiency, high cost and "contactless" security at the end of express delivery. As a new solution for the "last 100 meters", it has become a new outlet in the industry.

  Recently, the State Post Bureau issued a circular on the economic operation of the industry in the first half of 2021. The data shows that the business volume and revenue of express delivery reached 49.39 billion pieces and 484.21 billion yuan, up by 45.8% and 26.6% respectively year-on-year, and the growth rate was more than twice that of the same period of last year. In 2020, the business volume of express delivery service in China will increase to 83 billion pieces with a growth rate of 30.7%, up by 5.4 percentage points over the previous year.

  Express cabinets rise quietly.

  With the approach of "Double Eleven" and "Double Twelve", China’s e-commerce sales will once again set a new world record. As a supporting service for e-commerce, the express delivery industry in China enjoys the bonus brought by the prosperity and development of online shopping, and at the same time, a large number of deliveries impact the terminals of major express delivery companies.

  In recent years, the express cabinet, a one-foot square box, has gathered the forces of users, property, couriers, express companies and express cabinet companies. In the "last mile" battlefield, it is crowded and unbalanced, and major industry giants have come to seize the market.

  From the whole service chain of express delivery, the terminal is a particularly important link, and it is also the link with the strongest user experience, so there is also a lot of room for innovation and improvement. In the current market structure, there are dozens of smart express box enterprises in China, including express delivery, e-commerce, property management and third-party service providers. Behind the accelerated layout, the Eight Immortals crossed the sea and showed their magical powers.

  According to the survey of the ways in which netizens interviewed by the State Post Bureau receive express delivery recently, express delivery stations, smart express cabinets and downstairs collection points have become the choices of most interviewed netizens, accounting for 26.3%, 21.2% and 20.5% respectively. In addition, some netizens interviewed like to wait for someone at home before arranging courier delivery. Only 13.7% of the netizens interviewed chose to place the courier at their doorstep.

  The reporter combed and found that the intelligent express cabinet has been launched for many years and still faces the problem of loss. The data shows that the net profit of HIVE BOX in 2019 and 2020 is-781 million yuan and-245 million yuan respectively, and the net profit of China Post Express is-517 million yuan and-159 million yuan respectively. The two major express cabinet brands with the highest market share are facing the problem of long-term losses.

  In fact, since the outbreak, the problem of "the last 100 meters" of express delivery has also been highlighted. During the closed management of the community, the express cabinets in the community can only be idle. With the lifting of the ban on couriers in the community, contactless delivery still becomes people’s habit, and the frequency of use of express cabinets has further increased. However, after the express counter started to charge overtime, it affected the willingness of price-sensitive residents to use it to some extent.

  Or become the outlet for capital to March.

  On January 7, 2021, Henan Yida Warehouse Information Technology Co., Ltd. completed a strategic investment of nearly 35 million yuan. The investors were JD.COM Group, Suning Group and Pinduoduo. Yida Warehouse Company was established on December 16th, 2020. Less than one month after its establishment, it was jointly invested by three giant home appliance companies.

  The three major e-commerce giants and three fierce competitors in the industry have targeted the smart express cabinets at the same time, causing huge waves in the industry. Express cabinet manufacturers have ushered in a "good start" in 2021.

  In fact, the express cabinet has many profit points and strong operability. According to industry experts, there is still a big gap in the number of express cabinets in China. Coupled with the development of the international market, the express cabinet industry is a blue ocean of 100 billion yuan, which is a new outlet for entrepreneurs and investors. The development potential of intelligent express cabinets is huge.

  Buhua, the regional director of Rookie Europe, told the reporter that due to the COVID-19 epidemic, overseas consumption has shifted more to online, and the contactless pick-up mode provided by the self-counter has been greatly welcomed in overseas markets. It is estimated that by the end of the year, the rookie will set up 650 sets of self-reporting cabinets throughout France.

  According to Tianyancha data, as of October 17 this year, there are more than 800 express cabinet related enterprises in China. Among them, more than 280 enterprises will be added in 2020, a year-on-year increase of 54%.

  According to a report previously released by the State Post Bureau, in 2020, the number of intelligent express cabinets nationwide will reach 750,000, with a market size of nearly 30 billion yuan.

  In just a few years, the smart express cabinet industry has been competing with each other and capital has swarmed, forming a pattern of three major systems, namely, express delivery system, e-commerce system and third party, competing on the same stage. During this period, HIVE BOX is also accelerating its external financing and expansion. Following the shareholder’s capital increase of 500 million yuan in June 2016, the company completed two rounds of financing totaling 5 billion yuan in 2017 and 2018 respectively, and in September 2017, it acquired CIMC E-stack for 810 million yuan, becoming the first in the industry terminal layout.

  At present, many foreign companies are studying how to turn cars into mobile express cabinets. Just last week, Skoda, a sub-brand of Volkswagen Group, announced that its Skoda Digilab mobile joint venture company has started testing the on-board parcel delivery system with two online retailers in the Czech Republic.

  JD.COM also launched a similar product earlier, named "Express Delivery to Car". The principle is similar. After the owner buys the order online, the purchased goods are sent directly to the trunk of the vehicle, and the courier receives the positioning of the vehicle through GPS signals. Authorized courier, after application, can open the trunk of the car without the presence of the owner, so as to realize proper delivery of goods.

  Solve the problem of unclear business model

  "As a terminal delivery facility, the express box has certain public service attributes, and its quasi-publicity is feasible." Mo Yuanming, a researcher at Chongqing Jingyu Provincial Institute of Situation and Development Planning, said that top-level design should be accelerated, specific guidelines should be formulated, and "fine accounts" should be calculated well, which can not only achieve universal low prices, but also ensure the enthusiasm of market players for development.

  The cost of express cabinet mainly involves hardware, maintenance personnel and site expenses. The cost of a set of cabinets (hardware) ranges from 18,000 yuan to 60,000 yuan. The increase or decrease of operation and maintenance personnel is also positively related to the number and coverage of express cabinets, that is, the more express cabinets, the more people are needed, so the cost is relatively stable. The cost of the venue is generally directly related to the express delivery volume, location, demand and whether it is exclusive.

  "The end of the courier service must be changed." Zhou Yang, senior director of the strategic planning department of Yuantong Company, told reporters that if all of them are delivered to the school, 150 express items per courier per day are already "ceilings", but the number of Yuantong express items increased by more than 40% last year. During the "Fourteenth Five-Year Plan" period, the absolute volume of the entire express delivery industry will be even larger, and the problems caused by limited personnel will become more prominent.

  Chen Shunfeng, president of ZTO Express Tuxi, said that in the future, Tuxi will be turned into a terminal network brand that meets the diversified needs of users such as express delivery, commerce and comprehensive services. Taking logistics as the cut-in, business flow as the income, and the diversified comprehensive services of the whole community scene as the stickiness, rabbit happiness has become an indispensable part of the delivery link.

  "The current business model of the express cabinet is still unclear." Wang Yong, a logistics expert and visiting professor at the Royal Swedish Institute of Technology, told the reporter that at present, the main income of express cabinets depends on charging couriers as little as 30 cents, and most of them are storage fees in 1 yuan, so the income source is relatively single. Although HIVE BOX and Cainiao Post Station have developed other businesses such as advertising and retail, they have achieved little.

  Xu Yubin, CEO of HIVE BOX, once explained the business logic of building a courier cabinet in HIVE BOX: on the one hand, it is to make money from courier companies, "to reduce the requirements for labor skills with unified service standards, so that courier companies and users can feel stable terminal courier services." On the other hand, it makes money from the client. "HIVE BOX digs deeply into user behavior data. In the future, we will drive this chain through technology."

Chopsticks Brothers’ new film "Nie Yinniang" is a follow-up project.

A film called The Legend of Nie Yinniang has been approved.

    1905 movie network news On December 23rd, the Film Bureau released the latest issue of the film script for filing and project announcement. Tang De International, New Yuan Ye, Hengye and other companies all exposed the latest projects, and Chopsticks Brothers’ new film "Fake Bodyguard" was also impressively listed. In addition, a film named "The Legend of Nie Yinniang" was officially approved, which has nothing to do with the film directed by Hou Xiaoxian.

Nie Yinniang attracted a follow-up work, Chopsticks Brothers’ new film named Fake Bodyguard.

    Nie Yinniang the Assassin, directed by Hou Xiaoxian, has been filmed for many years and finally released this year. Although the box office performance is not good, the film is of excellent quality and has a high status in the hearts of fans. The film also won many awards such as best film and best director at the Golden Horse Award. Now, a film named "The Legend of Nie Yinniang" has been approved. The synopsis of the story is: in the middle of the Tang Dynasty, the buffer region was divided, and Nie Yinniang, a chivalrous woman, sacrificed herself and took care of the overall situation to protect Wei Bo from the war, thus writing an epic story.

    Judging from the plot, although the protagonists are all Nie Yinniang, they are different from Hou Xiaoxian’s version, and some of them have deviated from the original trend and become more grand, even using the word "touching" to describe them. The filing unit of The Legend of Nie Yinniang is Zhejiang Dongyang Zhongguang Film and Television Culture Co., Ltd. Beijing Branch, but none of the production and distribution companies of The Legend of Nie Yinniang has this one.

Chopsticks Brothers’ New Works Exposed

    Last summer, Chopsticks Brothers’ film was released in the mainland, and the box office finally exceeded 200 million. After that, the two have no new works. After the announcement of this project, their new film named "Fake Bodyguard" was also exposed. The screenwriter was Wang Terry, and the story took place in South Korea, but the protagonist was "three people in life service". It seems that Shawn and Wang Terry will invite others to star together this time. The synopsis of the story shows that the protagonists met the top killers when they came to Korea, which can’t help but remind people of the Korean killers played by Chopsticks Brothers in "The Raptors of Old Boys Crossing the River".

The Golden Horse Award for Best New Director Bi Gan’s New Work

    In addition, Bi Gan, who won the Best New Director Award at this year’s Golden Horse Award, will also start shooting a film called The Last Night of the Earth, which is his second feature film.

Tang De International will shoot Ghost Train.

    Tang De International, a company that once invested in Jackie Chan’s new film, also released a new work "Ghost Train" this time. The screenwriter is Fuhai Yi, who once wrote a film starring Song Jia with Su Xiaowei. Most of the story of Ghost Train happened on the train, including the disappearance of the last carriage and the fact that it still runs without the front of the car. It is mainly thrilling.

    In recent years, Fujian Hengye Film Co., Ltd. has released three new films at one time, namely "My Dad is a liar", "Evil Neighbors from Heaven" and "Wow! There is a demon, and the three films are of different types.

The "European Raiders" previously exposed by Yinrun was finally established.

    As early as March this year, during the Hong Kong International Film Festival, Yinrun announced that it would launch "European Raiders", which was directed by Ma Chucheng, continuing the style of the previous "Raiders" series of films, with an investment of over 100 million yuan, and would invite first-line stars to star in it. By the end of the year, the film was finally approved. It tells the story of three bounty hunters. When they compete with each other, they are involved in European gangs, the CIA of the United States, the European Union’s anti-crime alliance and other organizations.

China Baowu Taigang Group launched two new stainless steel products in the world-State-owned Assets Supervision and Administration Commission of the State Council

High-end electronic products such as mobile phones will become more intelligent, lighter and more durable because of China Baowu’s steel products. On May 12th, two new products, 0.07mm ultra-flat stainless steel precision strip and stainless precision strip with no texture surface, were launched in the world by China Baowu Taigang Group.

Can I buy a dual-clutch gearbox? Read these ten items before making a decision.

Is your car a dual clutch gearbox? Will you buy a car equipped with a dual clutch gearbox?

In recent years, in order to get rid of the intellectual property rights and technical restrictions of AT gearbox and gearbox, some car companies have achieved overtaking in corners of automatic gearbox. Coupled with the advantages of direct shifting, small power loss, light weight and low fuel consumption of dual-clutch gearbox, the majority of car companies have increased the research and development and production of DCT dual-clutch gearbox, and achieved remarkable results, and a large number of dual-clutch gearboxes with excellent technology and stable performance have emerged.

The dual clutch automatic transmission is based on the manual gearbox. Different from the manual gearbox, two clutches in the dual clutch are connected with two input shafts, and the gear shifting and clutch operation are realized automatically through the mechatronic module integrating electronic and hydraulic components.

Powershift can be divided into dry type and wet type, and the main difference is the different cooling methods. Dry powershift is cooled by air, while wet dual clutch is cooled by oil. The cooling effect of oil is better than that of air, especially in the scene of frequent clutch use. Therefore, the wet dual clutch automatic transmission has the characteristics of good ride comfort, strong stability and long service life, which is more popular among consumers and becomes the mainstream of dual clutch.

The following small series will lead you to learn about the top 10 mainstream DCT gearboxes in China and see who is the strongest.

The above are ranked according to the torque they bear.

Dongfeng 6DCT150 is a wet dual-clutch gearbox jointly produced by Dongfeng and Getrag Company. Established in 2012, Dongfang Style Traak Automobile Gearbox Co., Ltd. is a joint venture established by Dongfeng Company and Getrag International Company, each holding 50% of the shares, to jointly develop, manufacture and sell low-torque dual-clutch gearboxes. In the second half of 2014, the design of 6DCT150 wet dual-clutch gearbox was finalized, with six forward gears and one reverse gear, which can withstand the torque of 150Nm. Later, engineers further improved that the current maximum torque can withstand 200Nm, and it does not exceed 60 kg after filling oil. Using the unique micro-sliding friction technology of Getrak, after the clutch is fully combined, a thin oil film will be attached between the friction plate and the clutch plate, which can effectively alleviate the instantaneous speed or torque fluctuation and bring a smoother driving experience. The gearbox is a lightweight and compact third-generation powershift, equipped with cascade gears and intelligent execution system, and its transmission efficiency, fuel economy, shift comfort and other indicators have reached the leading level of similar products.

The gearbox matched by Beijing Hyundai Elantra 1.4T is D7GF1 dry dual clutch gearbox produced by Beijing Hyundai Elantra, with the maximum torque of 220 Nm. The reliability and stability of 6at gearbox produced by Mobius are very high, second only to. This 7-speed dry dual clutch adopts motor-driven shift technology, and its internal components are mainly two dry dual clutches, two clutch actuators, two sets of shift actuators and three-axis planetary gear sets. In terms of reliability, it is higher than most dual clutches on the market, but the inherent problems of dry dual clutches such as fear of heat and low speed frustration are still not well solved. In the case of extreme congestion, these two gearboxes may have overheating protection, and the market reputation is average.

In order to get rid of the dependence on Aisin 6AT gearbox, Volkswagen is the first car company to popularize dual-clutch gearbox on a large scale, and it is also an example for some domestic car companies to learn and imitate. Volkswagen DQ200 is a seven-speed dry dual-clutch gearbox, which can bear the maximum torque of 250NM. At present, it is produced by Volkswagen Transmission Dalian Co., Ltd. in China. DQ200 has the advantages of fast shifting speed, simple structure, high transmission efficiency and good fuel economy, with a weight of only about 70KG. It is mainly matched with Volkswagen 1.4T engine and is widely used. There were many complaints in the early days, but with the continuous improvement of production technology, the proportion of complaints about this gearbox is gradually decreasing. However, the inherent disadvantage of dry dual clutch is that there is no cooling of gearbox oil. In the process of frequent start and stop of dry dual clutch, the clutch is easy to overheat, which leads to clutch plate jitter, abnormal noise and even damage.

Jianghuai is one of the earliest independent automobile companies in China to develop DCT dual-clutch gearbox, and it mainly cooperates with others. Its clutch module and electromagnetic box are from Bogwarner, and TCU software program is from Germany. The net weight of JAC’s 6th gear powershift is only about 71.5kg, which is due to its two sets of internal and external nested shafts. 6DCT gearbox adopts JAC’s unique patented clutch protection design, with two additional clutches. When the clutch is overloaded, it can quickly turn on overload protection and safety cut-off. In order to realize automatic transmission control, there are as many as 12 sensors connected in TCU control unit, which can effectively monitor the working state of the whole machine in real time and cope with various complex environmental conditions. Jianghuai 6DCT gearbox optimizes the gear position and gear arrangement, reduces idling parts, shortens the axial length, and effectively improves the product compactness. The gearbox also adopts high-precision and high-efficiency internal meshing rotor oil pump and new DCT special lubricating oil, which greatly reduces the energy loss of the system, makes the fuel consumption of the whole vehicle close to the level of manual transmission with the same gear number, and the transmission efficiency is as high as 95%.

It is one of the earliest manufacturers of dual-clutch gearbox in independent brands. "DM21", a new generation of MEGA TECH 7-speed wet powershift, is the latest fist work of SAIC. The total weight of the transmission is 82KG, which is the third generation product independently developed by SAIC. The economy, ride comfort and durability have been further improved, and the torque capacity has reached 300Nm, which has changed the problems of the previous generation gearbox, such as frustration and abnormal noise. This gearbox has an ultra-high transmission efficiency of 97%, and is equipped with an original three-cavity independent cooling and lubrication system for gear cavity, hydraulic control module cavity and clutch cavity, which effectively ensures fuel economy and stability. In addition, it also uses the ultra-high pressure zero leakage control system to ensure the accuracy and speed of shifting. This one is mounted on MG6, and its overall performance is remarkable, and its shifting is smooth and silky, with both power and handling. The transmission was rated as one of the top ten transmissions in the world in 2021.

The 7-speed wet powershift used by Changan Automobile is produced by its own company, and its code name is DF727. It was successfully developed in 2017. In 2019, DF727 was applied to self-owned brand passenger cars in batches, with the production and sales reaching more than 100,000 units. DF727 is the flagship product of Qingshan Industry in recent two years. Once it was launched, it was favored by the market, with compact structure, high-precision clutch thermal management strategy and intelligent gear shifting technology. Its comprehensive transmission efficiency reaches 94.3%, and it is widely used in 1.4T and 1.5T blue whale engines in Chang ‘an, such as UNI-T, CS55, etc., with excellent power response and fuel economy. At present, there are three known models: DF727A/B/C, and the maximum bearing torque is extended from 270NM to 300NM. The actual driving experience is not bad, but the probability of DC270 being frustrated when driving on low-speed congested roads is slightly higher. The quality of the gearbox produced by Qingshan with military quality is guaranteed.The transmission was rated asIn 2021, the world’s top ten speed changes in the Dragon Pan Cup.

When it comes to gearboxes, we have to admire Chery, which is a unique brand in China and independently developed CVT15 and CVT25. However, the torque of CVT gearboxes is limited. With the equipment of Chery’s strongest 1.6T and 2.0T high-torque engines, Chery has to equip them with gearboxes with greater torque. So Chery and the cooperative 7DCT300 came into being. 7DCT300 is the third generation gearbox with intelligent execution system, which can be horizontally centered and horizontally front-mounted, and the maximum input torque can reach 320Nm. Five high-performance clutches and gear shifting are adopted, and the gears equipped with smooth gear shifting and fast response speed, accurate sliding control of clutches and high-precision equipment processing also bring excellent NVH performance to the transmission, with comprehensive transmission efficiency exceeding 96% and net weight as low as 65kg. With the advantages of leading transmission efficiency, excellent shift comfort and low power consumption electro-hydraulic intelligent execution system, 7DCT300 has been favored by many OEMs.

The 7-speed wet dual clutch used by Geely is jointly developed by Geely and Geely, and is compatible with 48V light hybrid plug-in hybrid system. 90% of the suppliers of Geely’s dual-clutch gearbox are the top suppliers in the world. Compared with the traditional dry or wet DCT, Geely 7DCT adopts the latest generation of electro-hydraulic execution system. This not only retains the oil-cooling mode of wet double clutch, but also adopts the high-efficiency motor-driven shifting process, and adopts the controllable variable oil pump, which can supply oil on demand, and improves the power efficiency to the extreme, with the highest transmission efficiency reaching 97%. The great improvement of efficiency is closely related to the reduction of internal friction, and the loss of the product itself is further reduced through a number of technologies, such as electronic gear shifting, separate electro-hydraulic control of clutch, optimization of housing to reduce lubricating oil spill, and cooperation with famous lubricating oil manufacturers to develop low-viscosity DCT oil, so as to finally reduce internal friction and improve transmission efficiency. At present, Geely is widely used in the Lectra series, etc. From the current actual use effect, Geely’s 7-speed wet dual clutch is relatively stable.

As early as 2011, BYD developed a 6-speed dry dual-clutch gearbox with reference to Volkswagen DQ200 gearbox, which is the earliest car company in China to master the technology of dry dual-clutch gearbox. In 2013, BYD introduced the 6-speed wet dual-clutch gearbox 6DT35, which is still the result of reverse research and development. This gearbox can now be seen on BYD’s Song and Song MAX models. Its maximum torque is 350Nm and its weight is 94KG. At present, it only matches some small displacement engines. According to the owner’s report, BYD’s 6-speed wet dual-clutch gearbox has problems such as frustration and abnormal sound, and its quality needs to be improved. Fortunately, in 2020, BYD launched a new 7-speed wet dual-clutch automatic transmission. By simulating various operating conditions, the transient dynamics simulation analysis was carried out, and the unbalanced load with each gear was continuously corrected, so that the gear meshing was smoother, the impact between gears was reduced, and the smoothness of the transmission was better and the failure rate was lower. In terms of durability, the official claims that it can match the service life of AT. In addition, the new gearbox has higher transmission efficiency, more fuel saving, lower noise control, more direct power, and the transmission efficiency is as high as 95%, which is already in the leading position in China.

Great Wall, a gearbox, is based on itself and draws on the strengths of others.Great Wall DCT450 seven-speed wet dual-clutch gearbox, its comprehensive quality is recognized as a high-end product in the industry at present. Mainly manifested in: first, high reliability, accessories from famous enterprises,For example, the bearing of the gearbox is Schaeffler, Germany, and the dual-clutch module is Bogwarner TCU, USA. This gearbox consists of 157 parts, of which only 18 parts such as the outer shell and gear are produced by Great Wall itself, and all others are supplied by internationally renowned suppliers. Second, the noise control is excellent, it uses very low viscosity lubricating oil, and with the design of this gear pendulum vibration reduction flywheel, the noise of the gearbox is about 10 decibels lower than that of other similar levels; The third isIt can bear a large torque, and the maximum torque is as high as 450Nm. The adaptive models include mainstream 1.5T-2.5T gasoline engines, because the peak torque of these machines is basically between 250 and 450 nm. Fourth, the transmission efficiency is high, and the transmission efficiency of DCT450 gearbox is also very high, reaching the high standard of 95%. There are not many DCT that can reach this level, so this machine has obvious improvement effect on the performance of vehicles.

Biden will announce that the United States will join the global vaccine program and provide $4 billion in funding

  BEIJING, Feb. 19 (Xinhua) According to the US Chinese website, a senior US government official said that US President Biden will announce on the 19th that he will provide US$ 4 billion for the COVID-19 Vaccine Implementation Plan (COVAX) led by WHO, which aims to help poor countries promote vaccination.

  Biden will outline the plan at a virtual meeting with G7 members on the 19th. The official said that the White House plans to allocate $2 billion immediately, which was approved by Congress in December 2020. Biden will also promise another $2 billion in aid in 2021 and 2022.

  The official said that the money will come from the funds already allocated by Congress for international vaccination and will not affect the Biden administration’s domestic vaccination plan. The Biden administration said this week that it is expected to vaccinate every American adult by July.

  According to reports, the Trump administration refused to participate in the COVAX program.

  COVAX plans to provide more than 330 million doses of vaccine in the first half of 2021, and about 145 countries will receive enough doses to vaccinate 3.3% of their population.

  In December, 2020, COVAX officials said that the donations in place were still $4 billion short of the pledged amount. If the donations were not fulfilled, both rich and poor countries would suffer from "protracted epidemic and serious economic consequences".

  The White House said it would release the second batch of $2 billion after other countries fulfilled their pledges and COVAX provided the first batch of vaccine doses to 92 low-income and middle-income countries.

Editor’s note: As for ATACMS missiles, we have been following the article "The red line of military aid is broken, and the army tactical missiles attack. How powerful is it?" Is there enough inventory? "ATACMS got a blood," Taurus "will be on the road, can the Kerch Bridge be saved? ",this missile is actually the equipment developed by the US military decades ago, and it is not new at all, but it still plays an important role on the battlefield in Russia and Ukraine.Today, Walker, a senior author of this issue, collected relevant war cases to show you what dazzling achievements it has made.

On November 17, 2024, foreign media suddenly reported that the U.S. Joe Biden’s government, which had become the left-behind government after the election, had lifted Ukraine’s ban on using American aid weapons to attack deep targets in Russia.

■ The Biden administration of the United States revealed that it has lifted the ban on US aid weapons against deep targets in Russia.

The Ukrainian side also acted quickly. Only two days later, in the early morning of November 19th, the Ukrainian army launched a long-range strike against the arsenal of the 1046th Logistics Center of the Russian Ministry of Defense near Karachev, Bryansk, Russia. It is about 115 kilometers away from the nearest Ukrainian border. It is reported that the Ukrainian army has launched six American-aided ATACMS Army tactical missiles, and at least 12 secondary explosions have occurred in the attacked Russian arsenal, which can prove that the attack has been successful at least to some extent.

■ It is said that the Ukrainian army launched a video screenshot of ATACMS against targets in Russia.

November 19th coincides with the 1,000th day of the outbreak of the Russian-Ukrainian war, so this long-range strike by the Ukrainian army is of symbolic significance.

In fact, after receiving ATACMS from the United States in October 2023, the Ukrainian army quickly put it into actual combat, attacked the important targets of the Russian army, and achieved many major results. Let’s list some below, so that we can better understand the actual combat effect of this weapon.

First, the airport attack in October 2023

On October 17, 2023, Russian troops were attacked at two airports in the port city of the Azov Sea in southern Ukraine and Lugansk in eastern Ukraine, and suffered heavy losses. Subsequent live pictures and all parties confirmed that this was ATACMS’ first attack on the battlefield in Ukraine.

The attack revealed a lot of information for us.

Different from the past, this time the Americans confirmed to the outside world after the attack that they had provided ATACMS Army tactical missiles to Ukraine. This is, of course, to avoid alarming others and try to ensure ATACMS’ success in the first battle in Ukraine. At the same time, it also proves the importance of this kind of weapon from the side-other weapons provided by the United States to Ukraine have not received such "treatment".

■ As can be seen in the photos that flowed out afterwards, the Russian Ka -52 helicopter gunship stationed at the airport was covered with traces of being hit by cluster munitions.

The war report issued by Ukraine’s Ministry of Defence said that "Operation Dragonfly" destroyed nine Russian helicopters, an anti-aircraft missile launcher, an ammunition depot and several airport special vehicles at midnight on October 17th, and damaged the airport runway. However, the actual losses of the Russian army are likely to far exceed this number.

According to the analysis of satellite images after the attack, 15 Russian helicopters may have been damaged at Berdyansk airport and 6 helicopters may have been lost at Lugansk airport, which makes the total number of destroyed/damaged Russian helicopters possibly reach 21, which is more than twice the number listed in the Ukrainian army battle report. This may also be the biggest loss suffered by the Russian air force in a single day since the war.

■ Satellite images of Berdyansk Airport taken on October 19, 2023 show that as many as 15 Russian helicopters may be destroyed or damaged.

■ Satellite images of Lugansk Airport taken on October 18, 2023 show that six Russian helicopters may have been destroyed or damaged.

It can be seen that the Ukrainian army used the long-range large-scale cluster munitions projection capability provided by ATACMS to attack various military assets that the Russian army stayed and deployed at the airport.

According to the photos of ATACMS missile wreckage on the spot, the missile used by Ukrainian military to launch the attack is the oldest Atacms Block I (MGM-140a), which belongs to the last batch of missiles of this type produced in 1996, with a maximum range of 165 kilometers. The warhead contains 950 M74 anti-personnel/anti-equipment submunitions.

■ It is said that the ATACMS missile remains were found at the scene, and the visible model is MGM-140A, which was produced in the 10th week of 1996.

In fact, these missiles have already expired, belonging to the earliest batch of more than 1,200 expired ATACMS stocks in the US military arsenal that have not been refurbished. It shows that when the US military provided the first batch of ATACMS assistance to Ukrainians, it did not use its own active weapons, but used the battlefield in Ukraine to "destock" in disguise, thus saving a lot of costs for refurbishing missiles.

This is consistent with the analysis of the number of ATACMS that the United States can provide to Ukraine in the second part of the report. However, it needs to be clarified that the active ATACMS of the US military no longer include cluster munitions warheads, but all of them are changed to single warheads. If the Ukrainian army wants to use cluster munitions to launch attacks, it can only consider those ATACMS that have expired.

■ It is said to be the M74 submunition dud scattered by ATACMS cluster munition warhead.

This practice is actually not uncommon, and it can be regarded as a routine operation of foreign military aid. At present, Israel, a hot spot in the world, has received many similar weapons in military assistance in previous Middle East wars. How to give full play to them depends on the recipient’s own ability.

From another point of view, these missiles, which were produced nearly 30 years ago, can be hit as soon as they arrive, and they can be hit accurately, with amazing results. It is also the best advertisement made by the American Military Industry Group.

■ It is said that the Ukrainian army launched a video screenshot of ATACMS.

In this war case, there are obviously serious problems in the Russian military’s response. Because it is no secret that the United States will provide ATACMS to Ukraine, the signs that it will debut in September are quite obvious. Moreover, the airport in Berdyansk has long been targeted by the Ukrainian army. It is the main base of the Ka -52 armed helicopter that poses a great threat to the Ukrainian armored forces on the southern front. It can be said that it is a thorn in the side of the Ukrainian army. However, the Russian army still placed many helicopters on the airport runway in the open air as usual, and did not think of evacuation until after being attacked, which was a typical "better late than never".

■ After the attack, the Russian army evacuated all the helicopters at Lugansk airport.

Second, the airport attack in April 2024

Because the Pentagon secretly provided Ukraine with a batch of new ATACMS in the military aid on March 12, 2024, the Ukrainian army seized the opportunity to launch a relatively large-scale ATACMS missile attack on the Russian army’s Jankoy Air Force Base in Crimea from the night of April 17 to the early hours of April 18 before the US Congress passed the aid bill.

The air base is about 150 kilometers away from the front line. It is the main starting point for the Russian air force to support the battlefield in southern Ukraine and an important logistics hub for the Russian army. According to previous reports, the Russian Air Force stationed more than a dozen Ka -52 alligator and Mi -28 Catastrophe helicopter gunships here, as well as four Su -25 Frog Foot attack aircraft.

■ The location of Jankoy Air Force Base.

In order to protect this important air base, the Russian army also deployed S-400 or S-300 ground air defense missile systems here. Through the radar and missile coverage of the air defense system, the Russian army can observe and control the activities of the Ukrainian army in the airspace of southern Ukraine from here.

However, these ground-based air defense missile systems are the first targets of the Ukrainian attack. According to Ukrainian sources, the attack destroyed four S-400 or 300 air defense missile launchers, three radars of the air defense missile system, an air defense missile system control station and some other facilities. According to sources from Russia, the Ukrainian army used a total of 12 ATACMS in this attack, which were divided into two groups to attack the airport. The first group had seven missiles and the second group had five missiles. The Ukrainian army still uses ATACMS missiles with cluster munitions. Judging from the pictures of the wreckage on the scene, it is likely to be the same type of missiles used in the attack in October 2023, and both are the oldest expired MGM-140A in the US military inventory.

■ Satellite images taken on April 19, 2024 showed that several components of the air defense system at Jankoy Air Force Base were destroyed after the Ukrainian army attacked with ATACMS.

Based on the analysis of live video, photos and satellite images taken in the daytime the next day, the above results are basically in line with the actual situation. The video released by the Ukrainian Ministry of Defence shows that at least 7-8 ATACMS missiles have been launched. As can be seen from the video screenshots taken at the scene afterwards, at least three launch vehicles of S-400 or 300 air defense missile systems were burned. On the high-resolution satellite image taken during the daytime on April 18th, it can be seen that at least four main components of the air defense missile system deployed in the southern area of the airport were hit and burned.

■ Screenshots of live video that flowed out afterwards showed that at least three launch vehicles of S-400 or 300 air defense missile systems were burned.

It can also be seen from the images of Fire Information Resource Management System (FIRMS), which provides close to real-time fire data through on-orbit satellite infrared sensing technology, that there were at least six fires at the Jankoy Air Force Base in Crimea at the time of the attack.

■ The "Fire Information Resource Management System" shows that there were six fires at Zhankoy Air Force Base during the ATACMS attack.

In addition to the S-400 or 300 anti-aircraft missile positions, two aprons on the north side of the base were also attacked. In addition, around the six aprons on the easternmost side of the base, there are also traces of being attacked by cluster munitions. Other large-scale scorch marks nearby may belong to the short-range air defense system deployed at the airport, such as "Armor -S1".

■ There are also a large number of burnt marks on the ground on the north side of the base, which may belong to other short-range air defense systems deployed at the airport.

Although the aircraft damaged by ATACMS’s attack can hardly be seen on satellite images, it does not rule out that the Russian army has removed them at the first time, so as to avoid the Ukrainian army and the outside world having the opportunity to analyze the attack effect more accurately.

On the evening of April 29th, the Ukrainian army used ATACMS to attack the military targets of Jankoy Air Base and Simferopol in Crimea. It was confirmed by satellite images that another S-400 or 300 air defense missile system deployed at Jankoy Air Force Base was hit. The Russian army then removed all the S-400 or 300 air defense missile systems from the airport.

■ On the night of April 29, 2024, the Ukrainian army once again used ATACMS to launch an attack on the Jankoy Air Force Base in Crimea and the capital Simferopol.

It is worth noting that Simferopol is also more than 200 kilometers away from the nearest front line, so it can be inferred that the Ukrainian army has begun to use the long-range ATACMS provided by the United States.

3. Attacking the assembly point of troops in May 2024

The video streaming on the Internet on May 1, 2024 confirmed that the Ukrainian army used ATACMS to attack a Russian assembly site or training ground in Lugansk State in the east. This location is located near Kuban town, about 80 kilometers away from the front line.

■ Cluster munitions loaded by ■ATACMS caused a large-scale explosion at the scene.

According to the video taken by the surveillance drone, about hundreds of Russian troops and at least three armored vehicles assembled there, and then about four ATACMS carrying cluster munitions hit this area, one of which may not have exploded, and at least one ATACMS directly covered the assembled Russian troops in the video, but the specific casualties are still unclear.

■ The surveillance drone photographed that the Russian army was gathering locally.

Fourth, the airport attack in May 2024

In the early morning of May 15th, 2024, the Russian Belbek Air Force Base on the Crimean Peninsula was attacked by ATACMS launched by the Ukrainian army, which was near Sevastopol, the home port of the Russian Black Sea Fleet, and about 230 kilometers away from Hellson. Some Russian media also speculated that the Ukrainian army launched ATACMS from the Ukrainian-Romanian border in the direction of Snake Island.

■ Rybar, a famous Russian military telegraph channel, speculated that the Ukrainian army might launch ATACMS from two directions to attack Belbek Air Force Base.

The Fire Information Resource Management System (FIRMS) of NASA monitored the fire at Belbek Air Force Base in space, which coincided with the attack time of ATACMS.

■ The fire information resource management system shows the fire at Belbek Air Force Base.

■ Unexploded submunitions carried by ATACMS warhead were found in the relevant area after dawn.

Follow-up information shows that a set of S-400 ground air defense missile system 92N6E radar set up by Russian army here was destroyed.

■ Destroyed S-400 air defense system 92N6E radar wreckage.

■ This is an intact S-400 air defense system 92N6 radar vehicle.

In addition to this radar, the losses of the Russian army also include the fuel and lubricating oil storage facilities at the airport and two S-400 air defense system launchers. Two other MIG -31 fighters were destroyed and three Su -27 fighters were damaged. Seven soldiers from the 27th Mixed Aviation Division and the 31st Air Defense Division were killed and 12 others were injured.

■ Satellite images of Belbek Air Force Base taken after the attack showed that at least two MiG -31 fighters were destroyed.

5. Attacking the Sevastopol military port in May 2024.

In the early morning of May 19th, 2024, after attacking the air defense position of Belbek Air Force Base near Sevastopol, Crimea, the Ukrainian army launched a long-range strike against the Russian Black Sea Fleet warships in the military port.

In this round of attack, the Russian Black Sea Fleet’s 22,800 Karakurt-class frigate "Cyclone" (633) was attacked by two ATACMS. Six people were killed, 11 were injured and the warship was sunk.

■ The sunken Russian Black Sea Fleet "Cyclone" (633) small frigate.

The sinking of the warship shows that the Ukrainian army has obtained ATACMS with a single warhead instead of cluster munitions. This warhead is actually the WDU-18/B high-penetration bursting disc warhead of the U.S. Navy’s Harpoon anti-ship missile, which weighs about 227 kilograms and contains about 98 kilograms of DESTEX high explosive, which is quite destructive to small frigates.

■ Scene photos of the small frigate "Cyclone" (633) when it was hit.

6. Attacking air defense positions in May 2024

At about 12: 50 noon on May 22, 2024, the Ukrainian army attacked the Russian S-400 air defense system position near the Mospines airport in Donetsk with five ATACMS.

■ Schematic diagram of the specific location of the attacked Russian S-400 air defense position. It’s about 64 kilometers from the front.

On the attacked S-400 air defense position, two transmitters were destroyed, one transmitter was damaged, one 96L6E radar was destroyed, and the 55K6E command center of the S-400 system was destroyed.

■ S-400 system 96L6E radar vehicle destroyed by ATACMS attack.

■ S-400 system transmitter destroyed by ATACMS attack.

Interestingly, the Russian S-400 air defense system was trying to intercept it when it was attacked. It seems that the interception was not successful, and this S-400 system was hit and destroyed by ATACMS. This also effectively debunked the war report that the Russian Ministry of Defense has repeatedly claimed to successfully intercept ATACMS.

■ The Russian S-400 air defense system desperately launched missiles to try to intercept ATACMS, but it was finally hit and destroyed by the latter’s cluster munitions.

In fact, there are still many actual combat cases about ATACMS in the Russian-Ukrainian battlefield. Due to the limitation of space, I won’t list them all here. If you know any other combat cases, please leave a message in the comment area and let the editors select them.

From the performance of these examples, it can be seen that the Ukrainian army has already had the ability to use this weapon continuously and launch a large-scale, long-range, rapid and lethal precision strike against Russian deep targets.

At the same time, the fact that several airports and other important targets have been hit by ATACMS, or even the air defense missile system used to protect airports has been directly hit, also shows that although the Russian air defense radar can easily find ATACMS with its flying apex height of about 50 kilometers and non-stealth design, its air defense system, including the most advanced S-300/400 ground-based air defense missile system, cannot effectively intercept ATACMS.

■ The maximum range of ■ATACMS is about 300 kilometers, which will seriously threaten many military targets in Russia, especially important ammunition depots, logistics nodes and command and communication centers.

Russian military logistics has always been one of its most obvious shortcomings. In the summer of 2022, after the "Haima" rocket entered Ukraine, it was through the precise attack on Russian ammunition logistics nodes and headquarters that the battlefield situation was reversed. Since then, the Russian army has been forced to move these important facilities backward or even put them in its own territory, which has affected its own supply efficiency.

The United States’ release of restrictions on Ukrainian troops’ use of ATACMS to attack Russian deep targets will further weaken the Russian military’s logistics capabilities, thus having a far-reaching impact on the war situation.

The author has something to say.

Since the outbreak of the Russian-Ukrainian war, WeChat official account, the "armored shovel historian", has been silently tracking and recording the whole process of the war. We believe that there are not many media outlets in China that can make this work as solid, detailed and comprehensive as ours. With these raw materials, we can make an in-depth and reliable analysis of the situation. I hope our hard work can get everyone’s recognition and support, thank you!

Extended reading:

The red line of military aid was broken, and the army tactical missiles attacked. How powerful was it? Is there enough inventory?

ATACMS gets a blood, "Taurus" will be on the road, can Kerch Bridge be saved?

It’s not easy to be original. You’d better look at it if you order it.
