阴极电流密度 meaning in Chinese

cathode current density
catodic current density
catodic density

The experiment result shows that the operating conditions have a significant effect upon the chromium content , and it increased with the raise of current density and ph value , but decrease with the temperature raise of the bath
温度、 ph值、阴极电流密度对镀层中铬含量的影响较大。试验结果表明：降低温度、提高ph值和阴极电流密度有利于提高镀层的含铬量。
The hardness and corrosion resistance were evaluated by , the anticorrosion mechanism was also discussed by xps as well . the composited content of particles in coating was high when 0 . 5 % super - 3900 was added into al2o3 suspention before plating the composited content increased with the increase of al2o3 concentration in plating solution and the time of stirring before plating and increased as a peak curve with plating temperature , cathodic current density and ph value
超分散剂super - 3900加入量为0 . 5 % ,对al2o3悬浮液分散后加入时,获得的镀层复合al2o3含量高,并随着镀液中al2o3含量、镀前搅拌时间增加而增加,镀层中al2o3含量随着施镀温度、阴极电流密度、 ph值的增加呈先增加后减少的变化。
