Directed to improve the lubrication system of continuous casting equipment for steel-making system,with the deficiencies of complex operating condition,multi-point lubrication,difficult check and frequently oil adding,this paper proposes the optimized design and improved plan,which added the concentration adding oil system and the discharge supervise and control machine at the original system.

Low-voltage centralized compensation for consumer reactive power are mainly studied,the basic principle and technical features of low-voltage centralized compensation method which is widely used in China at present are introduced in brief,and the problems needing attention and treatment measures are emphatically analyzed when in designing,erection,commission and maintenance.

An inquiry is given mainly into automatic compensation of reactive power of low - voltage power suply system in plants and mines with automatic centralized compensation controller so as to increase power factor, decrease line loss, save energy and transmission and transformation equipment and materials and improve the quality of power supply and safety.

Analysis of Fund Management Model of CNPC;

Through recombination and structural reforms several times, the incorporate pattern of upper and lower reaches of a operation, of produce, supply and marketing, of domestic and foreign trade has came into being in CNPC.
