Agricultural science and technology innovation should strengthen market consciousness, efficiency consciousness and benefit consciousness

  Hangzhou, August 16 (Reporter Yu Qin) On the morning of the 16th, Governor Zheng Shanjie came to the Provincial Academy of Agricultural Sciences to investigate agricultural science and technology. He stressed: to consolidate and strengthen the basic position of agriculture, we must not relax at any time. It is hoped that the Provincial Academy of Agricultural Sciences will thoroughly study and implement the spirit of a series of important instructions of the Supreme Leader General Secretary on agricultural science and technology innovation, conscientiously implement the arrangements of the Ninth Plenary Session of the 14th Provincial Party Committee, further improve its position, emancipate its mind, further enhance its market awareness, efficiency awareness and benefit awareness, further play its role as the main force and system platform for promoting the overall leap of agricultural science and technology in the province, bravely shoulder heavy burdens and climb the peak, seize the day and make great efforts, in order to promote "strengthening agriculture through science and technology and strengthening agriculture through machinery" in our province.

  From the scientific research platform, breeding base, and agricultural machinery and equipment exhibition site, Zheng Shanjie went into laboratories, greenhouses and border paddy fields, cordially visited agricultural researchers, learned more about the breeding of new varieties, cultivation experiments and marketing of agricultural scientific and technological achievements, and fully affirmed the achievements made by the Provincial Academy of Agricultural Sciences in recent years. He said that agricultural science and technology innovation has unlimited potential and prospects, and at the same time, it also makes agriculture infinite. The majority of scientific researchers must establish a strong market orientation, work hard on the application of agricultural science and technology that farmers most expect and urgently need, and do a good job in the article of "forcing basic research with applied research and leading applied research with basic research" to create more achievements, benefit more people and write a more wonderful life in the vast fields.

  Zheng Shanjie pointed out that the way out for the high-quality development of agriculture in our province lies in improving the level of science and technology and mechanization. It is necessary to focus on "strengthening agriculture by science and technology and strengthening agriculture by machinery", strengthen problem orientation, identify the needs of agriculture, rural areas and farmers, focus on tackling key scientific and technological problems that restrict agricultural innovation and development, and effectively solve practical problems. We should establish the concept of input and output, give full play to the power of the market, pay attention to the main role of enterprises in innovation decision-making, R&D investment, scientific research organization and achievement transformation, promote the integrated development of Industry-University-Research, and improve the efficiency and benefit of agriculture through persistent scientific and technological innovation, so that agriculture can be competitive and farmers can earn money. It is necessary to deepen the reform of agricultural science and technology system, support technological research and development and technological innovation through institutional supply and institutional innovation, so that scientific researchers can benefit from the transformation of achievements, realize their personal value while realizing the interests of the country and society, and realize the "full revitalization" of agricultural science and technology innovation with "talent".

A Little Red Flower: tolerate suffering and let the little red flower bloom in my heart.


Special feature of 1905 film network Salt lake, blue sky, white teenager, white skirt girl; It’s so clean in the warm sun, between heaven and earth … …After watching the movie, this scene must be lingering. This beautiful ideal is an illusion that Wei Yihang (Jackson Yee), a teenager, can only see before he falls sick and faints.



A smelly-faced teenager in front of a stranger is a cold-faced teenager in the eyes of his family. The taciturn and perverse "juvenile rage" is vividly reflected in the adolescent boy Wei Yihang.



Under the extreme conditions of brain cancer, all this rebellion is nothing more than a hard shell for him to choose to "confront" or escape from his own misfortune and strange eyes around him. The first half of A Little Red Flower focuses on the ice-breaking process of this layer of defense.


As a key figure who lights up Wei Yihang’s gloomy life on the plot line, Ma Xiaoyuan (played by Liu Haocun), an optimistic girl, changes everything with love. As a "senior" brain cancer patient, her weapon to break the ice is not only initiative, but also empathy beyond simple communication.


Han Yan, a director with shooting experience, once again returned to the "normal" life perspective after throwing out the protagonist’s illness dilemma. Compared with "tumor jun" who had to be confined to the ward scene most of the time, "Little Red Flower", which made many viewers call "watching a youth film", obviously went further on the positive road to sadness.


However, no matter how beautiful the picture of youth love is, its basic starting point still cannot escape the awe of life.



The opportunity for them to really get to know each other is the conflict and opposition between them on whether their cancer patients need chicken soup for the soul; Several degrees of ambiguous clutch are closely related to the recurrence of their illness.


As a highlight of the film’s plot and post-publicity, the Weibo accounts of the two protagonists have become the key clue for fans to resume the film.



The homophonic interpretation of Wei Yihang’s "WEIYI’s voyage" reflects the firm but helpless yearning of the boy with cancer to travel to distant places. The screen name of "how far to roll" is extremely suitable for Ma Xiaoyuan’s jumping personality, and at the same time, it more intuitively reflects her drive for Wei Yihang’s courage to dream.



Although their journey together failed to go far, this journey of spiritual companionship with Xiaoyuan still stirred Yihang’s heart after her death. With this growth, Yihang ordered a beef rice takeaway for her haggard father in the name of a dead girl with cancer. After knowing the secret of the lover of Wu Xiaomei (Yun-peng Yue), the owner of the cancer patient group, she chose to support silently, which really realized the difficulty for her parents to spend everything to save themselves … …


The first little red flower in the film of the first voyage that passed on the spirit of "Little Red Flower" is Xiaoyuan’s reward for his "initiative for the first time in life". If the two people’s similar illness backgrounds and family status are reflected, you will find that the process of actively pursuing a small distance under the encouragement of the other party can also be regarded as a journey of self-discovery — — The so-called proactive process is actually the acceptance of all the states such as one’s illness and dreams, unbearable and great.



Years later, Wei Yihang, who has finally completed this "only" voyage on the Qinghai Lake, which is highly corresponding to the image of the dreamland in reality, saw the face of his eternal lover and found a little red flower belonging to life and hope in the "migration of 100 million sheep".


This little red flower has actually been in the heart of Yihang. With this performance, Jackson Yee undoubtedly won a "little red flower" for his fresh but wonderful actor resume.



Different from Li Xiaobei’s guardian-like depth and courage, it seems that he only needs to return to the corner of Wei Yihang, who is a teenager, but he tests the emotional transformation of actors in multiple dimensions such as illness, autism, love and release.


That scene’s confession to Xiaoyuan after drinking is not only a self-doubt and frustrated teenager who can’t help himself after getting drunk, but also an accusation of unfair fate after being substituted into the status of a cancer patient.



"I’m afraid I’ll die as soon as I take out my heart." In addition to talent, such difficult movements are naturally voiced, and Jackson Yee’s belief in performance deserves greater praise.


Also worthy of being awarded the "Little Red Flower" are Liu Haocun, who has performed more and more, and the parents who have made intensive contributions to tears. Under the joint efforts of each audience’s unique interpretation, this "little red flower" has gradually become the public’s vision mapping.



Perhaps, you and I, who can feel the red flower in our hearts, will find the lake in our dreams in 2021.

Rene Liu clarified the rumor of quitting the entertainment industry: milk tea will sing for a lifetime.


Photo of Rene Liu’s solo concert in Nanjing on April 28th, 2005. China News Agency issued a focus photo


  After the concert of Taipei Dome ended on November 29th, rumors about Rene Liu’s withdrawal from the entertainment circle spread all the way from Taiwan Province to the mainland. On December 3rd, Rene Liu admitted that she was troubled by the rumors of quitting these days. In fact, the media misread some of her words. She would not quit the show business, and she would sing all her life.


  Exit rumors begin with misunderstanding.


  There are several "evidences" for the media to speculate that Rene Liu intends to quit the entertainment industry, including her blog message "How to start is difficult, and how to end is even more difficult", saying "This is the last time" at the end of the concert, and saying "This is my graduation concert" to Bobby Chen. Bobby Chen later said, "I hurt her. She was really tired and wanted to rest.".


  Rene Liu said that she didn’t take this matter seriously at first and didn’t come out to clarify it. But these days, friends and performers have been calling to ask about the truth of this matter, which makes her realize that she must stand up and make a statement: she never said anything about quitting.


  With regard to writing "how to start is difficult, how to end is even more difficult" on the blog, Milk Tea said: "I often say this sentence, and I think it is the same whether it is a concert, feelings or life. As a result, everyone misunderstood. "


  At the end of the concert, I said, "This is the last time." Milk tea also explained the situation at that time. "I actually finished the performance that day, but the audience just refused to leave, so I had to come out again and say,’ This is the last time’, which actually means I can’t come on stage that night." As for Bobby Chen’s words, Milk Tea laughed that Brother Sheng quickly sent her a basket of flowers to apologize after seeing the report, saying that he had said something wrong.


  The reasons for quitting are not convincing.


  In addition to speculating that Rene Liu was going to quit the show business according to various signs, the media also analyzed the "three major reasons" that caused her to quit. One was a knee injury, the other was a lifelong event, and the third was that Golden Horse failed to make the shortlist.


  For these three reasons, milk tea also laughed and overturned them one by one: "My knee injury actually appeared before this year’s concert tour. The doctor did say that my injury was serious, but at the same time he assured me that after the operation, as long as I recovered well, I could still wear beautiful high heels in the future. I think many artists have worked hard and found a good home at the same time. Just like Zhang Aijia, Xu Fan and Jiang Wenli, they have been working all the time, but their families are doing well. "


  I heard that the failure to win the Golden Horse Award is also one of the incentives for media analysis. Milk tea shouted an exaggerated "OhmyGod": "I still have to win the Golden Horse Award for my lifetime achievement!"

Make up a physical health class for left-behind girls

  Cartography: Cheng Can

  "If there is an afterlife, do you want to be a girl or a boy?" When Wang Wenjuan, the head of the UU White Shell Project, raised this question in the public welfare class of a mountain school in Liangshan Yi Autonomous Prefecture, Sichuan Province, few people raised their hands "wanting to be a girl" on the grounds that they felt dirty and troublesome and disliked. "I want to ask this question to understand their gender identity." Wang Wenjuan said.

  Although this public welfare class of adolescent physiological health knowledge is only for girls, the initial atmosphere is a bit embarrassing. When hearing the words "menstruation", some girls buried their heads in their arms shyly, and some blushed and rubbed their hands. Until they found that the physical and health supplies sent by Wang Wenjuan were exactly what they usually lacked; Many of the physiological coping methods mentioned are not taught by my mother or sister. The confusion about the physiological period in their hearts has been solved little by little. One, two, three … … Girls began to raise their hands to ask questions and interact, and the atmosphere gradually warmed up.

  When Wang Wenjuan left, everyone blocked this warm-hearted little sister at the door of the classroom and hugged her. A girl insisted on sending her to the school gate and kept saying "Annigu" (Yi meaning: I love you — — Reporter’s note). A girl later wrote to tell her: "The sanitary towel you sent is like a care. I didn’t expect that I could get such meticulous care from others. I know how to protect myself in the future."

  After entering adolescence, there are always many "question marks" in my heart.

  During the first physiological period, Xiaofen (a pseudonym), a left-behind girl from a single-parent family in niujie Middle School, Weishan County, Yunnan Province, was not particularly panicked. She remembered what the biology teacher had said and bought sanitary napkins by herself. She didn’t feel well for a few days, but she didn’t tell her grandmother and her father who worked outside the home because she was shy. For the physiological period, she knows nothing about other precautions except that she strictly abides by her classmates’ "Don’t touch cold water and eat popsicles".

  It was not until the social worker of the "Spring Willow" left-behind girl care project came to the school that Xiaofen participated in the accompanying activities of the "Spring Willow" class and knew how to use sanitary napkins and how to wash underwear during the physiological period.

  Lu Ying, the director of "Spring Willow" project, and his team visited some mountainous areas in Yunnan and found that "menstrual poverty" is a common phenomenon. Some girls go to the nearest store to buy sanitary napkins, and they have to walk more than ten kilometers, and the types available are very limited; Influenced by their elders, some girls will still use traditional methods, such as toilet paper and menstrual belt, to cope with the physiological period, and social workers will learn to use sanitary napkins after repeated explanations.

  Like Lu Ying, Ma Yali, project director of Yicang Charity Service Center in Linxia Hui Autonomous Prefecture, Gansu Province, has also discovered the problem of "menstrual poverty" of many girls in rural areas since she participated in charity activities to help poor girls in 2018.

  When delivering "Xiao Ya Bao" including sanitary products and underwear, Ma Yali talked with local rural girls and learned that they were discovered by their mother only after the second physiological period or even the fourth or fifth time.

  Ma Yali also learned that many rural girls generally choose "what to buy cheaply" for physical hygiene products, and even some girls don’t change sanitary napkins often during the physiological period in order to save money, and there are also cases of gynecological bacterial infections.

  "Many girls always have a lot in their hearts after they enter adolescence ‘ Question mark ’ " In the past seven years, in order to help girls in rural areas correctly understand the knowledge of physical health, Ouyang Chenxi, co-founder of Lingmei Public Welfare Organization, has carried out related projects in Sichuan, Zhejiang and other places to help girls aged 11-19 to grow physically and mentally. When she once held an activity in Liangshan Prefecture, she found that some local girls didn’t know why their buttocks were bleeding, why they had a stomachache during their physiological period, and why they couldn’t control their emotions for a few days.

  "Without sanitary napkins, many rural left-behind girls can’t say it ‘ Pain ’ 。” Wang Wenjuan has been doing public welfare for more than five years, and many remote mountainous areas in Yunnan and Tibet are places that he often goes to. In addition to financial difficulties, she found that local girls still have a strong sense of "menstrual shame". This sense of shame also comes from the outside world.

  For example, I heard that Wang Wenjuan sent sanitary napkins, and some schools declined to say that "it’s easy to publicize the farewell things, but it’s hard to tell the outside world to send this (sanitary napkin)". Although some schools accept donations, Wang Wenjuan feels that the other side has a subtle attitude of "I wish I could finish donating and leave quickly". Every time this happens, she always "talks about conditions" with the school — — Adhere to the principle of "be sure to give lectures to children" and ensure that every girl who receives hygiene products can hear physiology classes and psychological counseling classes. "I want to bring love to the children by giving away hygiene products." Wang Wenjuan said.

  Giving away physical hygiene products is like "far from hydrolysis, near thirst"

  In Ouyang Chenxi’s view, the "menstrual poverty" of many rural girls is closely related to family economic conditions, family members and the degree of care from the outside world. No one tells them how to deal with such a private matter as the physiological period, and they don’t have much money to buy sanitary products themselves. Some left-behind girls’ daily pocket money is only more than 10 yuan. When it comes to "unlucky days", they always blush and ask their grandparents for money to "buy that".

  "Giving physical hygiene products to girls in remote mountainous areas is like ‘ Far hydrolysis cannot quench thirst ’ 。” Wang Wenjuan knew that "menstrual poverty" could easily lead to gynecological diseases and psychological problems of adolescent girls.

  When she was volunteering, Wang Wenjuan learned that a girl had severe dysmenorrhea, local itching and other symptoms, but there was no one at home to accompany her to see a doctor. She tried to take the half-assed girl to the local hospital, but when she heard "going to gynecology" at the door of the hospital, the girl turned her head and ran away. Wang Wenjuan later learned that this girl was very resistant to the word "gynecology" and would rather not see a doctor than go to "that place".

  However, Wang Wenjuan has also found some positive changes in the past two years. On one occasion, she went to three township schools in Shangrao, Jiangxi Province to give away sanitary products and give public lectures. Teachers from the county school also came to attend the lecture. After class, they also invited Wang Wenjuan to give a lecture in the county, and said, "Children in the county may not need donated sanitary products, but they need such physical hygiene classes." This recognition made Wang Wenjuan feel that the effort was worthwhile.

  “‘ Menstrual poverty ’ It is likely to affect girls’ physical and mental health development, including schoolwork. " According to Dr. Long Di, a professor at the Institute of Psychology of the Chinese Academy of Sciences and director of the Center for the Protection of Children and Families, some girls lack physical hygiene products and the intimate care of adults around them. Coupled with the mentality of menstrual shame shaped by social culture, they will have negative emotions such as tension, anxiety and fear, and even dysmenorrhea. "It is necessary to strengthen education and support for girls’ physiological period and mental health."

  How to strengthen the physical and mental health education and support for underage girls

  "In addition to giving rural girls more volunteer services in terms of physical health knowledge, they must be made to identify with and love women’s identity." Ouyang Chenxi has been thinking about how to add more experiential volunteer service activities to the public welfare science popularization activities of physical health knowledge in the future, so as to better perceive girls’ emotions and stimulate their self-identity and positive growth from the inside out.

  According to Long Di, according to the UN Convention on the Rights of the Child, to realize the best interests of children should ensure the two major needs of children’s safety and development. For the healthy growth of underage girls, she believes that parents, teachers and education departments are duty-bound, especially the education department should work with relevant experts and parents to formulate effective measures to effectively protect and care for the healthy development of underage girls’ physical health.

  In addition, Long Di mentioned that the physical and mental health education services conducted by non-governmental public welfare organizations have been formed in recent years, and some ways have been explored. It is suggested that volunteers of public welfare activities pay special attention to respecting the living customs in underdeveloped areas, and do not have the attitude of "I am right, you are backward" and "I want to change you", but should explore with the recipients how to change the customs harmful to women’s physical and mental health, so that girls in poor areas have the opportunity to create a happy life.

  "There are too many girls who need sanitary napkins, and there are too many lists received, which are all backlogged, but the fundraising can’t keep up." At present, Wang Wenjuan is facing a lot of pressure to raise funds. She said: "Donating physical hygiene products is just a way. Wherever you donate, you should talk about the course. I hope that the needs and difficulties of poor girls can be well-intentioned and gently protected, and don’t let ‘ Menstrual poverty ’ Happened to children. " (Reporter Jiao Minlong)

Is the dual clutch a panacea? Demystifying Volkswagen gearbox technology

  [Original by Aika Automotive Technology Channel]

  Dual clutch gearbox, a once controversial but booming species. Twenty years ago, the dual-clutch gearbox was a rare animal. At that time, it was mainly used in the field of racing, which was far from consumers. Today, dual clutch has become a force that can not be ignored in the field of automatic transmission, and more and more new cars have begun to join this camp. In the process of popularization of dual-clutch gearbox, Volkswagen is an important promoter and practitioner, and many people’s cognition of dual-clutch begins with the letter "DSG".

Demystifying Volkswagen gearbox technology

  Looking AT the product line of Volkswagen Group in China, it is not difficult to find that the dual clutch has occupied more than half of the country, and the limelight has far overshadowed AT or CVT gearboxes. At the media communication meeting held a few days ago, Aika Automobile communicated with the staff of Volkswagen College, discussed the development history and product layout of Volkswagen dual clutch technology, and obtained the latest news of electrified gearbox.

  Volkswagen dual clutch family

  The history of dual clutch gearbox can be traced back to the first half of last century. In 1939, Adolphe Kégresse, a Frenchman, put forward the technical concept of dual clutch, but the pessimistic economic environment at that time hindered the implementation of this idea. Rudolph Franke, a German, was the first to apply for the patent of dual-clutch gearbox in 1940, and carried out experiments on trucks, but it was not put into mass production in the end. It was not until the 1980s that the dual clutch gearbox emerged in the field of racing and entered the mass production considerations of some car companies. The large-scale promotion of dual clutch should start from the beginning of this century, and the contribution made by Volkswagen Group can never be ignored.

  In the late 1990s, Volkswagen began to cooperate with Borg Warner on the mass production of dual-clutch gearboxes. In 2002, Volkswagen launched its first production car Golf R32 equipped with dual-clutch gearbox, and the Audi TT 3.2L model equipped with the same powertrain also went to the market the following year. Subsequently, Volkswagen gradually covered the dual clutch to golf, Touran and other models, and began to promote it on a large scale in 2007.

  The original intention of the development of dual clutch gearbox is to combine the high efficiency of manual gearbox with the convenience of automatic gearbox. In order to achieve this goal, the dual-clutch gearbox adopts a similar mechanical structure to that of a manual gearbox, and realizes rapid shift connection through two clutches. At present, the dual clutch gearbox has appeared in most models of Volkswagen Group in China. Volkswagen brand calls it DSG direct shift gearbox, while Audi brand names it S tronic.

  Among the above gearboxes, DQ200 is the only one with dry clutch. Although the torque limit of DQ200 is not high, it is enough to meet the needs of small-displacement turbocharged engines. Almost all the transverse 1.2T and 1.4T models of Volkswagen Group are using this gearbox. As the originator of DSG mass production, DQ250 was gradually eliminated and replaced by a 7-speed gearbox that paid more attention to fuel economy. DL series vertical dual clutch gearboxes are more common in Audi models, among which DL382 and DL501 are relatively common, while DL800 is a "high-end product" for sports cars with mid-engines.

  Evolution from DQ380 to DQ381

  If DQ200 is an excellent partner of EA211, then DQ380/DQ381 is a tacit partner of EA888. Since entering the era of EA888 Gen3, Volkswagen has used DQ380/DQ381 7-speed dual-clutch gearbox to replace DQ250 6-speed dual-clutch gearbox on a large scale in China, and soon the European market has followed suit. Both the front and rear gearboxes adopt wet clutches, and the main purpose of increasing gears is to improve fuel economy and cope with increasingly stringent emission regulations.

  DQ381 has taken a series of measures to reduce friction loss. The drive shaft and differential are equipped with low-friction bearings, and low-friction oil seals and low-viscosity transmission oil are used. DQ380 and DQ500 use mechanical gearbox oil pump, which consumes a lot of energy and cannot provide oil pressure continuously when the engine is stopped. DQ381 is equipped with mechanical oil pump and electronic oil pump at the same time, which reduces energy consumption on the one hand and improves the application scope and comfort of start-stop system on the other. Of course, TCU logic has also been upgraded, which is closer to consumers’ usage habits.

  Analysis of electrified gearbox

  In the mass product matrix, electrified gearboxes are divided into two camps: hybrid and pure electric. In China market, Volkswagen’s plug-in hybrid (PHEV) vehicles only use hybrid dual-clutch gearbox, while 48V light hybrid vehicles still use traditional dual-clutch gearbox. The DQ400e hybrid dual clutch gearbox adopts wet structure, which can bear the comprehensive torque of 400Nm, which is suitable for the high torque characteristics of PHEV system.

  Compared with the traditional dual-clutch gearbox, the core change of DQ400e is the addition of motor and its related components. Because the motor is added to one side of the input shaft, the length of the DQ400e gearbox is increased, which increases the difficulty of spatial arrangement of the transverse power system. In order to control the size of the gearbox, the engineer sacrificed the seventh gear and adopted the sixth gear scheme. DQ400e is equipped with plug-in products such as Magotan GTE, Tanyue GTE and Tiguan L PHEV. With the promotion of Volkswagen electrification strategy, this gearbox will appear in more models.

  Volkswagen is not a leader in the field of pure electric vehicles (BEV), but the menacing MEB platform still puts great pressure on many competing products. It is expected that by the end of this year, the ID brand products based on MEB platform will be made in China, and the new car will use APP310 power motor. The author was lucky enough to see the APP310 in kind at the communication meeting, but due to confidentiality reasons, I can’t show pictures to readers for the time being. It can be revealed that APP310 not only can provide stronger power output, but also has a more exquisite structural design, and the thickness of its electronic control device is reduced by more than half compared with APP290.

  Editor’s comment:The development of dual clutch in China was not smooth sailing, and various stories made it controversial, but the market finally proved the existence value of dual clutch. Today, environmental protection is becoming more and more important, and the dual clutch has also derived a hybrid version, which is compatible with the motor with a compact structure. The future will eventually belong to a single-speed gearbox, and the exquisite APP310 makes people have unlimited expectations for the electric age of Volkswagen.
