| 摘 要： | 针对电火花放电机理中的极性效应这一问题做了进一步的研究。为考察两电极的蚀除情况，进行了单脉冲实验，结果发现在煤油中大脉宽放电条件下正极的蚀除量大于负极，这与实际加工中的结果不符。通过参考和分析等离子通道中电子和正离子的运动，并对上述现象给出了探讨性的解释。

| Abstract: | The problem of polarity effect in EDM is researched in this paper. In order to find out deterioration of anode and cathode, experiment with single pulse is taken in kerosene oil. The deterioration of anode is found larger than that of cathode even in the condition of large pulse width,which is contradictory to deterionition in EDM machining with continuous pulses.This phenomenon above may be explained through analyzing the movement of electron and positive ion in plasma canal. |
