In some cases, the use of pulse current still can reduce the lumber, improve the hydrogen cathodic current efficiency, thus reduce pinhole, striped and hydrogen brittleness, etc.
在某些场合下,使用脉冲电流还可以减少氢的析出、提高阴极电流效率,从而减少针孔、条纹和氢脆等。
But the step motor efficiency is low, the ability is not big, load drag pulse equivalent cannot too big, speed range is not big.
但步进电机的效率低,拖动负载的能力不大,脉冲当量不能太大,调速范围不大。
The small current of the slow pulse could efficiently decrease the ionic concentration polarization and increase the charging efficiency.
慢脉冲中的小电流有效地控制了离子浓差极化,提高了充电效率。
