1. this product is a new kind machinery induction - type electrical energy appliance. it adopts high coercive force aluminium nickl cobat material to make the special structure magnetic - hanged magnetic - propelled bearing. when it is electrified to operate, interrepulsion is produced between the bearing and the anxle so that it is electrified to operate. interrepulsion is produced between the bearing and the anxle so that it is suspend station. the friction loss is very small. it not only reduces energy exhaustion by a wide mardin, but also prolongs lifetime to 20 years and above

鎳礦床成因上屬巖漿礦床,其成礦作用有巖漿分結作用、硫化作用、巖漿熔離作用及熱液作用等,但巖漿熔離成礦作用不發育,熱液作用僅佔次要地位,富硫圍巖的同化混染對礦床的形成有特殊的意義。
Because of its excellent properties, such as high strength, high module, wear resisting, and etc., sicp was added to ferroalloy as a reinforce phase. but the intrinsic difference between the bonds led to poor fabrication of the composites. in this paper, the effects of alloying, sintering, and heat - treatment on the properties and microstructures of sicp / ferroalloy - based composites were studied, : it was found that sic particles reacted with ferroalloy when sintered in 1100
