Concern from Academician Li Dequn: Special "Note" science and technology to report to the country, and the talent of "plastic"

At 10:34 on September 5, 2022, a member of the Communist Party of my country, an expert in the formation of famous materials in China, an academician of the Chinese Academy of Engineering, the head of the national college Huang Diannian teacher team, the national outstanding science and technology worker, the professor of the School of Materials Science and Engineering of Huazhong University of Science and Technology Comrades, died in Wuhan at the age of 78.

In the more than 30 years of working at Huazhong University of Science and Technology, Academician Li Dequn has focused on the innovative spirit of non -stop scientific research, leading the development of digital intelligent forming technology in China; he has spared no effort to support his nobility and morality, interpreting the materials of materials to report to the country and ethical talents. The heart of the teacher.

He said: "Scientific researchers must not shrink back in the face of difficulties. To step on difficulties at the feet, there must be a spirit of not being afraid of hardships and bravery, but also to make up for the tenacity to make up for it."

He said: "To be a university teacher with a name, it is not enough to do scientific research. It is not easy to teach and educate people.

He has a good writing and missed the two teachers in the middle school and college era with affectionate strokes. In the article entitled "Missing Mestery, Professor Xiao Jingguang" published in 2021, he wrote: "Mr. Xiao, who is in love, if there is a life, I will be your student again!"

Now, he follows the teacher and leaves the infinite memory of future generations.

Road to study -from Yujiashan to Cornell

"Entering Huagong, I may pick up the textbook again."

On the eve of the reform and opening up in 1978, Li Dequn, a graduate of Tsinghua University, who was 33 years old and put in the county, was a ten -year technician. Before the interview, Li Dequn tried to inquire about the possibility of the admission. Professor Xiao Jingguang, who had a strong Hunan accent, cleverly gave him a reassurance: "There are many graduate courses, and the study will be very nervous. Click the foreign language and mathematics. "The leader of the retest asked Li Dequn with a smile:" Professor Xiao, do you understand? "" Understand! "Li Dequn said affirmatively.

After obtaining graduate students in Huazhong University, the teacher has from Xiao Jingguang. In order to retire the study time of more than ten years of abandonment, "older student", he seized all the time that could be used to make up for English, relive Russian, study mathematics ... On the car and on the fluttering ferry, Li Dequn could always read a book in a certain corner, as if the noise around him had nothing to do with him -at this time he realized that he was walking on the side of the road to read foreign languages ​​by walking on the road. The "nerd" of the calculation mathematical problem is not staying, "or," I don't think I don't stay, I am also such a "nerd '".

The picture shows Li Dequn's study in the dormitory of the second students (1979).

Li Dequn resisted the heavy academic pressure, overcome the difficulties of studying the two foreign languages ​​of Britain and Russia at the same time, and completed the 240,000 -word Russian monograph translation that Xiao Jingyuan gave him to the most optimized and automated research on the development of forging mold design in China. Basis. Thanks to the inspiration of the translation, he sorted out the idea of ​​carrying out the research of mold CAD. He said to Xiao Jingguang: "Don't stay for me, I have the determination to break the boat." During the master's degree, Li Dequn achieved the automation and optimization research and verification of the automation process in China for the first time in China. Scientific research fast lane combined with computer technology.

The picture shows the mold CAD/CAM technology hosted by Li Dequn through the results identification of the results (1984).

In order to meet the needs of the rapid development of domestic injection molding, in 1986, the 41 -year -old Li Dequn went to the University of Cornell University under the introduction of Xiao Jingguang to visit the study of the simulation technology of the injection molding process. Soon after, he helped a South Korean visiting scholar to solve the problem of two years that had plagued the research team, realized the dynamic display of three -dimensional graphics, completed the development of basic graphics libraries in Fortran environment, and wrote a limited meta -grid graphical interaction process. With the overcome of new tasks after another, Li Dequn was appreciated and trusted by the teachers and students of the research team. Professor K.K.wang, the head of the research group and academician of the National Academy of Engineering, said to Tang Xingbo, the chief consul of the Chinese consulate in New York: "Mr. Li invited to the United States. I have seen the best scholars who come to our school from the mainland. "

The picture shows Li Dequn at the University of Cornell to assist students to design products with graphics software (1987).

Li Dequn practiced the creed of lifelong learning. He said: "The hard work I understand includes four aspects: concentration, hard work, initiative, and health." He said so, and insisted on exercising for an hour every day. He was the main player of table tennis at the College of Materials; after retirement, he still kept the habit of reading and writing and not let yourself stop thinking; he used his own personal experience to send a new student. Don't be afraid of the failure and defeat in scientific research.

Injection molding -from followed to leading

In 1987, after Li Dequn developed a commercial two-dimensional cooling system analysis software for the US AC-Tech company, he received an olive branch of the United States. The salary was a astronomical number compared to the monthly salary of the country at that time. He declined the invitation of the United States, and resolutely chose to return to China to return to China University, in response to Xiao Jingguang's call for "establishing a high -level academic team engaged in the research of injection molding technology in school", holding "can shorten the gap through hard work, or even surpass the gap, or even surpass The strong faith of the International First -class level "joined the" July Five "national research project" Color Electric Mold Sinical "project, hosted the research and development of injection molding mold CAD/CAE/CAM Laboratory, the first research on digital injection molding in China. At that time, the domestic injection molding technology was not yet available. The production process was not only expected, but also the product's sub -product rate was also very high. A large number of molding molds rely on imports. Li Dequn realized that there is only one choice to completely get rid of the situation of being subject to people: "What we need, we study what we study." Clarified that Li Dequn led the school's injection molding research team to report on hand. Injection molding simulation software ". In the early 1990s, the research team developed the Huacang CAE independently, which played an important role in the localization of my country's molds.

The picture shows Li Dequn's first domestic injection molding research team (1987).

At the beginning of this century, Li Dequn hosted the results of the National Key Laboratory in injection, casting, stamping, welding and other aspects of injection, casting, stamping, welding, etc., to refine the simulation of common technologies, create a shared technology platform, and effectively promote the commercialization and commercialization of the modeling software of our school's materials. Wide application has become a well -known brand in the field of forming simulation in my country. In the past 10 years, Li Dequn has actively promoted the integration of material forming and artificial intelligence technology, and developed intelligent equipment for the formation of materials. In order to get rid of the production process of traditional plastic products to artificial dependence and achieve automated and intelligent production, he led the team's smart injection molding machine, leading the development direction of the intelligent development of injection molding equipment.

In more than 30 years of scientific research, Li Dequn won the second prize of the National Science and Technology Progress Award three times, and won the second prize of the National Natural Science Award. In 2015, he was elected as an academician of the Chinese Academy of Engineering.

Teaching according to the aptitude -from science and technology to the country to Lideshu people

Adhering to the teacher's heart, for more than 30 years, Li Dequn has presided over the national teaching team and national boutique courses. The publishing textbook monographs have a monograph and won 3 first prizes of provincial and ministerial teaching achievements. A large number of materials in the field of formation.

He is Yan Shi. Li Dequn has a lagging subject of an out -of -school doctoral graduate student. He brought the student to the school and arranged directly at his desk to learn with himself. Under such urges, the student obtained a doctorate degree and became a professor of Zhejiang University of Technology in less than ten years.

He is even better. Li Dequn found that student Zhou Huamin was very talented in mathematical modeling and algorithm research, so he specially focused on training and handed over the bottleneck problem that plagued the development and promotion of injection molding simulation software at home and abroad. "He is willing to study, be able to endure hardships, be able to endure hardships, clear ideas, keen eyes, and the most difficult topic can be given to him." Li Dequn was full of trust and appreciation for Zhou Huamin.

The picture shows Li Dequn and doctoral student Zhou Huamin in Hong Kong in 2004.

If you want to overcome this problem, you must comprehensively use the knowledge of fluid mechanics, thermodynamics, and computer graphics. For this topic of cross -doctoral dissertation, Zhou Huamin has also felt embarrassed. Can you win yourself? But Li Dequn encouraged him, "using a good direction and difficult problems to occupy the high point of academic research systems." Under the guidance of Li Dequn, Zhou Huamin carried out assumptions and deductions over and over again, seeking solutions one by one, and eventually successfully established a new mathematical model and algorithm to attack this world -class difficulty. Surface model, a iconic result of an iconic result rated by international colleagues as "an important milestone in the history of injection molding simulation" was born, and it was also born as the most widely used analysis model in the field. Zhou Huamin also grew up as a winner of the National Outstanding Youth Science Fund and a special professor of the "Yangtze River Scholar" of the Ministry of Education.

For more than 30 years, Li Dequn has worked hard to be a good teacher and friend of students. In the past, traffic was inconvenient, and many students could not go home during the Spring Festival. Li Dequn invited them to come to home for the New Year, care about studies, and greet life. Shi Shi, bowed, and kind, is the unanimous impression of many people who have been in contact with Li Dequn. However, if there is an appointment, he always arrives earlier than others.

The picture shows Li Dequn for undergraduates.

The "zero distance" in the communication between teachers and students is also reflected in classroom teaching. Li Dequn also faced the embarrassing situation of less than half of the attendance rate, so he urged every classmate to convey his requirements to the absence of his classmates. He hoped that everyone would take professional courses and "encourage Teacher Li." At the same time, he tried to change the teaching style and teaching content, explored the method of transition from narrative to inspiration, and mobilized the interest in learning by increasing exchanges and interaction methods. Students' attendance rates rose straight. Li Dequn's inspiration teaching method is very popular among students, and it has also become a teaching model for teachers of the School of Materials. He has repeatedly instructed young teachers to teach and educate people. It ’s not time to cook dumplings in the teapot — the belly can not be poured out. Instead, it is necessary to master the teaching methods, improve the teaching effect, and let students like to learn, understand, and remember." Gan is a ladder ladder. —— From the leader to the paving stone

For the students, Li Dequn is the teacher of the preaching of preaching, and a friend with similar interests. For young teachers, Li Dequn is the backbone of leading everyone to overcome difficulties and a mountain that can always trust and rely on. In early 2022, the team led by Li Dequn was awarded the team of Huangda Nian -style teacher in the national university.

The picture shows a team of teachers for the formation of digital materials.

"There are a lot of young professors in our team. Academician Li will use his experience and resources to support the growth of young people." Professor Wu Fengshun of the School of Materials said that Li Dequn's "biography" spirit is the biggest feature of digital material forming teacher team.

"I am directed by Academician Li. Without his care and support, there will be no results in this result." Professor Pang Shengyong, who is seen in the direction of welding simulation, admits that Li Dequn is to promote his firm power on the road of scientific research. Essence At present, he and the research team have developed software that can really be practical and engineered in the aerospace industry, but at first this study was not optimistic because of difficulty, upset, and difficult to persist. Li Dequn encouraged the teacher of Pang Shengyong and the research team: "This matter is very important. To do it, to do it, to do it well! This is exactly what the aerospace industry needs." He also gave his doctoral enrollment quota to the research group for research for research Transfer new forces. After the output of the research results, Li Dequn played his own academic reputation and strongly recommended to the academic and industry. "Our technology is reliable."

It is also helped by Li Dequn, as well as Professor Liu Yuqi, who is engaged in stamping and forming. "We have a lot of cooperation with Academician Li. This group can develop to this day. It is indeed indispensable for Academician Li's help and care." At the end of 2002, Liu Yu got up to the laboratory and just needed help. "I feel that Academician Li is a very The kind person, no shelf, is helpful, we all make forming simulation, they make injection molding, we make plate materials, often communicate and cooperate together, apply for topics ... "Professor Yan Chunze, who is engaged in the formation of adding materials in the team During the R & D project, there were many technical issues that could not be thought of. I wanted to call Li Dequn to ask, but considering that the elderly were older and worried about disturbance. After Li Dequn knew, he directly received the teachers to discuss the problem at home. "Academician Li really helps us, whether it is scientific research or life."

Li Dequn is always like this, looking at the growth of young people, but he has a lightness of his honor gains and losses. He provided all the technical materials he collected and sorted out abroad to use all the technical materials he collected abroad to use it, and recommended that young and middle -aged teachers undertake teaching materials to compile tasks. He mainly promoted the position of the first person in charge of the first person in charge of the "Eighth Five -Year" and the "15th Fifteenth" national research project, allowing young people to rank first in the provincial and ministerial awards.

The picture shows an innovative team of new and old combination, unity and mutual assistance, and climbing peak.

Li Dequn not only supported the scientific research of young teachers, but also did his best to their roads. In the first year of Zhou Huamin's teacher, Li Dequn did not let him teach. Instead, he arranged him to continue to listen to the "Material Processing Engineering" course for more than a year with the students. New "teacher inheritance.

In the team, Professor Zhang Yun started from Li Dequn since the junior college student innovation project. "Teacher Li has taught very detailed teaching and has been teaching the front line to do it. His preaching church has been passed on."

"I have been working in the field of material forming. After studying from abroad to independent innovation, we have witnessed the gap between us and developed countries decades ago. Progressive. The overall progress of the industry and some of my personal achievements are closely related to the peaceful environment of the party and the policy of science and technology. We are still in the journey of the great rejuvenation of the Chinese nation. Jun jointly builds the country. "This is the speech after Li Dequn won the first" Hubei Outstanding Talent Award "in November 2021.

At this moment, Yu Jiashan will no longer appear familiar to Academician Li Dequn. However, his colleagues and students are still on this campus, in the world of materials science, and in the broad world, for the common aspirations of Academician Li Dequn.

Academician Li Dequn!
