The conclusion was the follows， when the thickness of mother sheet was 2mm， the temperature of mother sheet was 800～850℃ and the smelting superheat was controlledas 10～30℃，the production of composite stainless steel strip would be possible.

Under the circumstance of the main connection of double busbar with bypass and four power incoming lines in Ningxia Tongxin substation,discusses the existing problems and implementation methods for the application of incoming line standby power automatic put-in system.

Study on F grade mica tape cured by middle temperature was developed;

Study on application of organic silicone adhesive on fireproof mica tape;

A new type curative accelerant for mica tape was studied to degrade the curing temperature and time which is low dielectric loss,low curing temperature,fast curing speed and good insulation property.
