Fabrication of the lightweight mirror is one of the key techniques for many large optical systems. CAD,CAM and CNC technologies are adopted in designing and manufacturing such mirrors in CIOMP. Better working efficiency and higher lightweight grade have been achieved. The results show that mirrors up to 70% weight reduction and 0.02λ(rms.) surface accuracy or better can be obtained.

Chemical Research in Chinese Universities 1991年第3期7卷 172-173页

作者： Xiao Fengshou (Department of Chemistry,, Jilin University, changchun)xin Qin and Guo Xiexian (National Laboratory for Catalysis, Dalian Institute of Chemical Physics, Dalian)

Recently, owing to high costs and increasing demands for better catalysts, it is worthwhile to improve its activity and selectivity, and reduce its costs. Adding secondary promoters such as phosphorus, boron, magnesium, titanium, zinc and ruthenium to Co-Mo/Al;O;catalyst has been proved to be one of the ways to attain this result. The addition of those metals or metal oxides changes the surface states of molybdenumstructure.
