at 10:34 on September 5, 2022, Chinese Communist Party member , Chinese famous materials formed experts, Chinese Academy of Engineering , head of the national college Huangdian New Year teacher team, national outstanding science and technology worker , China Zhongzhong University of Science and Technology University Comrade Li DeML2, Professor , Professor , School of Materials Science and Engineering, died at the age of 78 at the age of 78 due to the ineffective treatment of illness. For more than 30 years of
in 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 my country; he has spared no effort to support his junior's noble morality, interpreting materials to serve in the country, and heavily. The heart of the teacher of moral education.
said: "Scientific researchers must not shrink back in the face of difficulties. If you want to step on the difficulties, you must have the spirit of not being afraid of hardships and bravery, but also to make up for the tenacity."
said: "To become a named university teacher, it is not enough to do scientific research. It is not easy to teach and educate people. , I used affectionate brushstrokes to miss the two teachers in middle school and college days. In the article entitled "Missing Mestery, Professor Xiao Jingguang" published in 2021, he wrote: "Mr. Xiao, who is in love, if you come to life, I will be your student again!"
is now following Give descendants unlimitedly.
School of Study -From Yujiashan to Cornell
"Entering Huagong, I can pick up the textbook again."
1978 was renovated and opened. Li Dequn, a graduate of , Tsinghua University, came to the Huazhong Institute of Technology (now Huazhong University of Science and Technology), , who was under Yujia Mountain, to participate in the graduate retest. Before the interview, Li Dequn tried to inquire about the possibility of admission. Professor Xiao Jingguang, who had a strong Hunan accent, cleverly gave him a reassurance: "There are many graduate courses, learning will be very nervous. After you go back, you can learn more about it. "The re -examination team leader" The leader of the foreign language and mathematics said with a smile: "Do you understand Professor Xiao?" "Know!"
is admitted to Grand graduate student. The teacher follows Xiao Jingguang. In order to take back the study time of more than ten years of abandonment for more than ten years, he seized all the time that could be available to make up for English, relive Russian, study mathematics ... On the crowded buses, 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. , Even the "nerd" who calculated mathematics questions was not stayed.
The picture shows that Li Dequn Study in the Southern Second Student Dormitory (1979)
Li Dequn to stand the heavy school pressure, overcome the difficulties of learning the two foreign languages of Britain and Russia, and completed the 240,000 -word monopoly translation work given to him. It provides a basis for the optimization and automation research of forging mold design in China. 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 research and verification of mold forging process automation and optimization in China. Research fast lanes combined with computer technology with computer technology.
The picture shows the mold CAD/CAM technology of Li Dequn's research and development. University visits and devoted himself to the research of simulation technology of injection molding process. Soon after, he helped a South Korean visiting scholar solve the problem of two years of troubled the research team, realized the dynamic display of three -dimensional graphics, completed the development of basic graphics libraries in the Fortran environment, and compiled the finite meta -grid graphical interaction process.With the overcome of new tasks one 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 team and the academician of the National Academy of Engineering, said to Tang Xingbo, the chief consul of the Chinese consulate in New York: "Mr. Li I invited to the United States. I have seen the best scholars who come to our school from the mainland. : "The hard work I understand includes four aspects: concentration, hard work, initiative, and health." He said so, and did this. He insisted on exercising for one hour a day. , Still maintaining the habit of reading and writing, so as not to stop thinking; send a new life with your own experience, and don't be afraid of learning the failure and failure in scientific research.
injection molding-from followed to leading
in 1987, Li Dequn developed a commercial two-dimensional cooling system analysis software for the US AC-Tech company. It is an astronomical number. He declined the invitation of the US work, 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 research on 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 has joined the "July Five" national research project "Sinicization of Color Electric Mold" project, hosted the research and development of injection molding mold CAD/CAE/CAM The laboratory was the first to create a study of digital injection molding in China. At that time,
, domestic injection molding technology is not yet available, the production process is not only expected, but also the product has a very high rate of products. 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 restrained: "What do we need to 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 independently developed the Huacang CAE, which played an important role in the localization of my country's molds.
The picture shows that Li Dequn established the 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, welding and other technologies. The creation of a shared technology platform has effectively promoted the commercialization and extensive application of our school's material forming series simulation software, and 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 automation 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 the scientific research career of
for more than 30 years, Li Dequn won the National Science and Technology Progress Award second prize three times, and once won the second prize of the National Natural Science Award , and was elected as an academician of the Chinese Academy of Engineering in 2015.
The picture shows that Li Dequn won the National Science and Technology Reward
to teach —— From the Science and Technology Reporting to the State,
, he has adhered to the teacher's heart. Excellent courses, publishing textbook monographs 21 The ministry has won three first prizes of provincial and ministerial teaching achievements, and 106 graduate students have been guided to cultivate a large number of materials in the form of material forming for the party and the country.
He is Yan Shi. Li Dequn has a lag in an out -of -school doctoral degree. 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 , Zhejiang University of Technology in less than ten years.
He is even more good.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, has clear thinking, 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 that in 2004, Li Dequn and doctoral student Zhou Huamin visited
in Hong Kong to attack. Dr. Paper Selected topics, Zhou Huamin also felt difficult. Can experts and scholars from all over the world have not yet captured the difficulties. Can he win himself? But Li Dequn encouraged him, "using a good direction, difficult problems, and occupying 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. It was also known as the most widely used analysis model in this field. Zhou Huamin also grew into National Outstanding Youth Science Fund winner and a special professor of "Yangtze River Scholar" of the Ministry of Education. For more than 30 years of
HTML, 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 in the Spring Festival. Li Dequn invited them to come to home for the New Year, care about studies, and greet life. Shi Shi, kissed, and kindness is the unanimous impression of many people who have been in contact with Li Dequn. However, there is an appointment that he always arrives earlier than others, opens the door, and gets up to meet the visitors.
The picture shows that Li Dequn's "zero distance" in the communication of teachers and students such as Li Dequn
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 inspirational teaching method is deeply 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 fall out of stocks. Instead, it is necessary to master the teaching methods, improve the teaching effect, and make students like to learn, understand, and remember. Ladder -From the leader to the paving stone
, for the students, Li Dequn is the teacher of the preaching and confusion, and a friend with similar interest. For young teachers, Li Dequn is the backbone of leading everyone to overcome difficulties. A mountain that can be trusted and dependent. In early 2022, the team led by Li Dequn was awarded the team of Huangda Nian -style teachers in colleges and universities.
The picture shows that the digital material forming teacher team
"There are many young professors in our team, Academician Li will use his experience and resources to support the growth of young people." The biggest feature of the Teacher Teacher Teacher Teacher Teacher Teacher.
"I am deeply directed by Academician Li. Without his care and support, there will be no this result." Professor Pang Shengyong, who is seen in the welding simulation direction, admits that Li Dequn is to promote him on the road of scientific research firmly. strength. 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 is important. To do it, you must do it, you must do it well! This is what the aerospace industry needs."He also gave his doctoral enrollment quota to the research group to bring new strength to the research. After the research results were produced, Li Dequn used his academic reputation to recommend to the academic and industrial circles, "Our technology is reliable." .
Also helped by Li Dequn is Professor Liu Yuqi, who is engaged in stamping process simulation. "We have a lot of cooperation with Academician Li. The development of this group is indeed inseparable from Academician Li's help and care." "At the end of 2002, Liu Yuqi came to the laboratory alone and needed help from all sides, "I feel that Academician Li is a very kind person, has no airs and is willing to help others. We all do forming simulation, they do injection molding, we do sheet metal, and often Let’s communicate and cooperate together and apply for projects..." Yan, who is engaged in additive forming manufacturing in the team When Professor Chunze applied for a national key research and development project, he had many technical problems that he couldn't figure out and wanted to call Li Dequn to ask. However, considering that the old man was old and worried about disturbing him, Li Dequn directly took the teachers to his home to discuss the problem. , “Academician Li is sincerely helping us, whether in scientific research or life. "
Li Dequn was always like this. He valued the growth of young people more than his own honor. He unreservedly provided all the technical materials he collected abroad to young teachers for use, and We strongly recommend young and middle-aged teachers to take on the task of compiling teaching materials. He advocated for young people to take the position of the first person in charge of national research projects during the "Eighth Five-Year Plan" and "Tenth Five-Year Plan", and ranked young people at the top of provincial and ministerial awards.
The picture shows the innovation of combining old and new, uniting and helping each other, and climbing to the top. team
Li Dequn not only supported the scientific research of young teachers, but also devoted himself to their journey to become teachers. In Zhou Huamin’s first year as a teacher, Li Dequn did not let him teach, but arranged for him to continue to listen to the whole class with the students. More than 10 years of "Material Processing Engineering" course, which is also Later, it became the team’s teacher-to-teacher practice of “using the old to lead the new”. Professor Zhang Yun in the
team started studying with Li Dequn during the undergraduate innovation project in his junior year. “Mr. Li’s teachings are very meticulous and he has always been hands-on in the teaching field. The words and deeds of the church have been passed on. "
" I have been working in the field of material forming. I have experienced learning from abroad and independent innovation. I have witnessed the gap between us and developed countries decades ago. I am also pleased to see that many technologies have gone from being controlled by others to leading the world, and have achieved success in our industry. Proud of our rapid progress. The overall progress of the industry, as well as some of my personal achievements, are closely related to the peaceful environment and the policy of rejuvenating the country through science and technology led by the party. We are still on the journey of the great rejuvenation of the Chinese nation, and the country's science and technology is in the ascendant. I also look forward to more young talents working together to build the country. "This is Li Dequn's speech after winning the first "Hubei Provincial Outstanding Talent Award" in November 2021.
At this moment, the familiar figure of Academician Li Dequn will no longer appear in Yujiashan. But his colleagues and students are still here. On campus, in the Materials Department In the world of learning, in the vast world, they and Academician Li Dequn are moving forward for the common ambition.
Academician Li Dequn will go through the ages!
