Cathode surface, led to the decrease of the internal resistance increases, activity, make Germany sunshine greatly shorten the service life of battery.
阴极表面，导致内阻增大、活性下降，使德国阳光蓄电池的使用寿命大大缩短。

The insulating resistance on the coating surface of buried pipelines is a very important parameter which is directly concerned with the cathode protection effect.
地下管道涂层表面绝缘电阻是直接关系到阴极保护效果的一项重要参数。

The study also illustrates that the finer structure of porous bodies will be beneficial for improving the cathode emission uniformity and resistance to ion bombardment.
