Last week two European researchers received the Nobel Prize in Physics for discovering that a magnetic field significantly reduces the electrical resistance of certain atom-thin metallic sandwiches.
上周，两个欧洲的研究人员因为发现磁场能够大大降低某些原子薄金属三明治的电阻而获得了诺贝尔物理学奖。

The twice impulse process is employed to change the metallic structure of the resistance welding so as to improve the welding strength.
