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。

Along with the increase of the current density, cathode polarization effect, coating grain with increasing more and fine.

随着电流密度的增加﹐阴极极化作用随着增加﹐镀层晶粒越来越细。

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。

In the current era of ideological polarization, throughout the West, the Right and the Left diverge on almost every issue.

What makes it worse is that glib polarization is especially unfortunate given the current situation.
