Based on the model, the relationship between the main pulse frequency of supply power and the balanceable inter-electrode gap is discussed.

给出了脉冲电化学加工极间平衡间隙的数学模型，并据此讨论了高频群脉冲电化学加工中，电源主脉冲频率与平衡加工间隙的关系。

Such horizontal magnetic field will make the arc move out of the electrode gap, and reduce the interrupting ability of the vacuum interrupters.

这一横向磁场会将电弧吹向弧隙外侧，削弱了真空灭弧室的开断能力。

The results show that the long electrode gap leads to the positive column which is caused by the climbing voltage on the cathode surface due to the accumulation of positive ions.

结果表明，放电单元采用大电极间距可获得正柱区放电，正柱区的形成是正离子在阴极鞘层区不断积累将电位抬高所致。
