cathodic protection是什么意思

用法例句

Study of Cathodic Protection for Underground Structures at Gas Station;

加油站地下储运设备阴极防蚀之研究

Relation of current loss and impedance collapse to cathode corrosion in a POS;

POS阴极侵蚀与电流损失和阻抗崩溃的关系

Too low diffusion rate of the oxides in W matrix is the main problem for cathode erosion.

总结得出阴极烧蚀问题的关键是氧化物扩散速率太低，认为纳米材料具有高扩散速率等优异性能，可望通过制备纳米晶Ｗ－氧化物阴极以解决其烧蚀问题。
