Qian Weichang is one of the founders of modern mechanics in my country.

Good at applied mathematics, mechanics, physics, Chinese informatics, etc.

He has published more than 20 academic monographs such as "Large Disturbance Problems of Circular Thin Plate", "Elastic Mechanics", "Variable Element Method and Finite Element", "Armor-Piercing Mechanics", "Generalized Variational Principle", and "Applied Mathematics".

He has published more than 200 academic papers at home and abroad.

He made many groundbreaking achievements in scientific theory and engineering technology.

His main academic contributions are the unified theory of nonlinear intrinsic properties of plates and shells, perturbation solutions and singular perturbation solutions to large disturbance problems of plates and shells, generalized variational principles, analytical solutions of ring shells and Chinese character macro glyph coding (Qian code), etc.

The "Shallow Shell Large Disturbance Equation" he proposed in his early days was hailed as the "Qian Weichang Equation" by the international academic community; on the problem of large disturbances in circular thin plates, the perturbation method with the central disturbance as a small parameter proposed by him was

Internationally known as "Qian Wei's long method".

His work on the problem of large disturbances in circular thin plates won the second prize of the National Science Award from the Chinese Academy of Sciences in 1955. His work on the generalized variational principle won the second prize of the National Natural Science Award in 1982. In addition, there are many scientific research projects.

The results won the Beijing and Shanghai Science and Technology Progress Awards respectively.

Recently, Professor Qian Weichang's work on the non-Kirchhoff-Raff hypothesis plate and shell theory is a new contribution to the basic theory of solid mechanics.

In 1997, he won the "Science and Technology Achievement Award" from the Ho Leung Ho Lee Foundation.

Qian Sanqiang: Since the founding of New China, Qian Sanqiang has devoted himself wholeheartedly to the creation of the atomic energy industry.

He served as deputy director and director of the Institute of Modern Physics (later renamed the Institute of Atomic Energy) at the Chinese Academy of Sciences.

In 1958, he participated in the construction of atomic reactors assisted by the Soviet Union and brought together a large number of nuclear scientists (including his wife). He also recommended outstanding talents such as Deng Jiaxian to the team for developing nuclear weapons.

In 1960, after the central government decided to rely entirely on self-reliance to develop the atomic bomb, Qian Sanqiang, who had also served as deputy director of the Second Ministry of Machinery, served as the technical chief and chief designer.

On the eve of the 50th anniversary of the National Day, the Central Committee of the Communist Party of China, the State Council, and the Central Military Commission posthumously awarded the "Two Bombs and One Satellite Meritorious Service Medal" made of 515 grams of pure gold to Qian Sanqiang in recognition of this scientific leader's great contributions.

In 1940, Qian Sanqiang obtained a French national doctorate and continued to work as an assistant with the second generation Curies.

In 1946, he married He Zehui, a talented woman in the same subject.

The couple achieved breakthrough results in studying the third fission of uranium nuclei, and were recommended to the world's scientific community by their mentor Joliot.

Many newspapers and publications in Western countries published this incident and praised "the Curies of China for discovering a new method of splitting the atomic nucleus."

In the same year, the French Academy of Sciences also awarded the Physics Prize to Qian Sanqiang. Qian Sanqiang passed away on June 28, 1992.

Qian Xuesen passed away on October 31, 2009.
