Changing of material resistance with applied magnetic field intensity is called Giant magnetoresistance ( GMR ) .磁电阻效应 是指材料的电阻随外加磁场变化而变化的现象.Striking beating patterns in magnetoresistance are observed in the vicinity of a...

The air resistance makes influence on the flight of an aeroplane.空气阻力影响飞机飞行.This increases their air - resistance and reduces the shock of impact when they hit the ground.这样就加大了空气阻力,并减少了它们着地时冲击力带来的震动.Engineers will work ...
