Qin (1208- 1268) was born in Sichuan (now Anyue), Han nationality. A famous mathematician in the Southern Song Dynasty, together with Ye Li, Yang Hui and Zhu Shijie, he was called the Four Masters of Mathematics in the Song and Yuan Dynasties. He studies astrology, rhythm, arithmetic, poetry, bows and arrows and creation. He worked as a magistrate and a farmer in Qiongzhou, and was later demoted and died in Meizhou.
1247, he completed the book "Nine Chapters of Number Books", in which the great derivative (the solution of a congruence system problem, now called China residue theorem), the triclinic quadrature and Qin algorithm (the numerical solution of the positive root of a higher-order equation) are important contributions of world significance, and an algorithm for solving the numerical solution of a higher-order polynomial equation with one variable-plus or minus cholesky decomposition is expressed.
2. Chen Tuan
Chen Tuan (871-989), a native of Chongkan County, Zhou Pu (now Longxi, Anyue, Sichuan), was nicknamed "Mr. Baiyun" and "Mr. Yi Xi". A well-known Taoist scholar and health care practitioner in the Northern Song Dynasty highly praised the study of Huang Lao. He has written monographs such as "Fetal Breathing Tactics" and "Zhi Xuan Pian".
In the fourth year of Tianfu at the end of Jin Dynasty (939), he visited Emei Mountain to give lectures, titled "Emei Real Person" and wrote "Watching the Heaven". Appreciating the Taoist priest of Mayi as a teacher, he is engaged in the study of Yi-ology, and has written Notes on the Righteousness of the Taoist priest of Mayi, Preface to Yilong Map, Theory of Taiji Yin and Yang, Taiji Map, and Congenital Fiona Fang Map.
3. Deng Longjiang
Expert in electromagnetic functional materials, from Anyue County, Sichuan Province, graduated from University of Electronic Science and Technology of China with a master's degree 1990. He has been engaged in the research of basic theory, preparation technology and engineering application in the field of electromagnetic radiation control materials for a long time.
A magnetic anisotropic nano-flake electromagnetic wave absorber was developed, and the design method of multi-layer and multi-spectrum electromagnetic radiation control materials was invented, which made important progress and industrialization in the aspects of "thinning" and "ultra-broadband" of electromagnetic radiation control materials, and ensured the demand of major engineering tasks.
4. Tang
Expert in inorganic nonmetallic materials, from Anyue County, Sichuan Province, 1956 graduated from the Chemical Engineering Department of Nanjing Institute of Technology. I have been engaged in the research of concrete engineering life for a long time. The alkali-aggregate reaction, an important subject affecting the life of concrete engineering, is systematically studied. The established rapid method has been set as the standard of France and China, and the alkali activity of aggregate has been identified for many large-scale concrete projects, and a reliable construction scheme has been put forward. The developed fast measuring instrument has been applied.
It has won national and provincial awards for many times, and the "alkali-aggregate reaction" won the second prize of National Natural Science 1987. Published more than 300 academic papers.
5. Kang Zhensheng
Born in Anyue County, Sichuan Province, he is a plant pathologist. 1982 graduated from plant protection department of northwest agricultural college, 1984 master of plant pathology of northwest agricultural university, 1990 doctor of northwest agricultural university.
He has been engaged in the research on the occurrence law and prevention and control technology of major wheat diseases for a long time. The pathway and mechanism of pathogenicity variation of wheat stripe rust were revealed, and the causes of wheat stripe rust becoming easy to change in summer in China were clarified. The comprehensive control technology system of wheat stripe rust was constructed, which effectively controlled wheat stripe rust in China. The infection mode and transmission route of wheat scab in panicle were found, and the key period of disease control was determined. The established comprehensive control technology system of wheat scab has been applied and popularized in the main wheat producing areas in China, and remarkable benefits have been achieved.
