Otherwise, a big error will be aroused.Being the effect of diffusion process, this method is not suitable for cathodal course.

由于受扩散作用的影响，这种等距离法适合对其阴过程进行修。

The CV values of the cathodal foils after electrochemical dip-coating and after ultrasonic dip-coating are similar to that after dip-coating stilly.

学浸胶中阴箔和超声浸胶的CV值与静置浸胶相差2％之内。
