Chief technical consultant------Academician Xu Guang-xian Academician Xu Guang-xian graduated from Shanghai Communication University in 1944. He went to US for study in 1947 and got his master degree in 1949, then in 1951 he got his doctor degree. When he was at Columbia University, he was elected to be a member of Phi Lamda Upsilon honour chemistry association and a member of Sigma Xi honour chemistry association. In 1951, he came back to China and assumed associate professor in the chemistry department of Peking University. In 1957, he went to atomic energy department which was newly founded to be the director of the radiochemistry teaching and research group and the vice director of the department. He was promoted to a professor in 1960. After the ten-year Cultural revolution, Prof. Xu came back to the chemistry department and has been engaged in research of rare earth chemistry. He successively assumed the director of the rare earth chemistry research center of Peking University, the director of the chemistry science department of the State Natural Science Fund Committee (1986~1993), the chairman of China Chemistry Academy (1986~1990), the vice chairman and vice honorary chairman of China Rare Earth Academy, the vice editor in chief of China Science, Science Aviso, Chemistry Transactions of Colleges, Inorganic Chemistry Transactions, the editor in chief of Journal of Rare Earths, the consultant of Rare Earths Information which is an organ of the rare earth office of China State Development Planning Committee. In 1980, he was elected to be the academician of China Science Academy. In the past 40 years, Academician Xu and his collaborators have been engaed in the educatin and research of quantum chemistry, rare earth chemistry, coordination chemistry and extraction chemistry, and have released more than 400 dissertations on civil or foreign publications, and have published 8 monographs and textbooks, and have been awarded the top prize of the State Excellent Textbook Awards. The Quantum Chemistry written by Xu and Li Lemin is the most elaborate textbook for postgraduates in quantum chemistry. The Rare Earths Solvent Extraction written by Xu and Yuan Cheng-ye has been awarded the first-class prize of the State Excellent Technical Books Awards.

          Mr. Xu presented the"theory of rare earth extraction in series" after ten years of research for rare earth extraction separation process. He together with Prof. Li Biao-guo and Prof. Yan Chun-hua have spread the application of this technology to main rare earth factories in China and have helped to create hundreds of million economical and social benefit for the country. This research fruit has been awarded the third-class prize of the State Natural Science Awards, the third-class prize of the State Technology Advancement Awards and the first-class prize of the State Education Council Technology Advancement Awards. His research on chemical bond theory, quantivalence theory, the structure rule of atom cluster and the electronical structure of rare earth compound has been awarded the second-class prize of the State Natural Science Awards and the first Heliangheli Technology Advancement Awards in 1994. His work has been highly recognized by the people in this industry at home and abroad. He has assumed the president of international science conference and has been invited to report at international conferences for several times. In 1987, he assumed JSPS Senior Research Fellow and gave lectures at Tokyo University, Kyoto University and molecular science institute in Japan. During 1989 to 1995, he assumed the president of Asia Chemistry League.
