The challenge, however, is extracting the spins to form a spin-polarized current and injecting them into a circuit without the polarization degrading along the way.

唯一的挑战是，如何提取自旋来形成一个自旋极化的电流，然后注入到电路中并保持极化在沿途不发生退化。

First the current distribution on the electrode polarization: do not exist on the electrode surface, the current distribution.

初次电流分布：在电极极化不存在时，电流在电极表面上的分布。

When the current density is too low, the cathode polarization effect, smaller coating, not even orange crystal bulky coating.

当电流密度过低时﹐阴极极化作用较小﹐镀层桔晶粗大﹐甚至没有镀层。

youdao

If the current is sent in the opposite direction, the polarization is reversed.

如果当前发送一个相反的方向，磁极指向就反转。
