另一方面也改变了金属腐蚀的电极电位，从而避免或降低了电化学腐蚀。

On the other hand also changes the electrode potential of metal corrosion, so as to avoid or reduce the electrochemical corrosion.

阴极极化：直流电通过电极时，阴极电位偏离平衡电位向负的方向移动的现象。

The cathode polarization: dc through electrode, the cathode potential deviating from the balance to the negative potential moves in the direction of the phenomenon.

其测量方法是将两个电极放在测试样品的表面，在电极之间施加一个电位差，并测量产生的电流。

It is measured by placing two electrodes on the surface of the test sample, applying a potential difference between them, and measuring the resulting current.

They carry a potential, that is, if you could - if you had a tiny, tiny electrical meter, you could one put one electrode on one side of the cell membrane, on the extracellular side and one on the intracellular side and measure, you would measure a potential difference; just like a battery you would measure a potential difference.

它们带有电势,就是说,如果你能有一个足够小的电位计,可以把一个电极放在细胞膜一侧,假设放在细胞外的一侧,另一个电极放在细胞内侧并测量,你能测到一个电势差,就像电池那样能测到电势差
