研究了在电磨损条件下，压力变化对复合材料磨损性能的影响。

It is conclded that under conditions of pure mechanical and electrical wear, the wear loss of composites increases linearly with wear time.

复合材料的电磨损体积与电刷的极性有关，正刷的磨损体积大于负刷的磨损体积；

The wear volume loss of positive brush is more than that of negative brush.

结果表明：在电磨损初期接触电压降较小，随着时间延长，接触电压降上升并趋于稳定；

The contact voltage drop was low in the initial stage of wear, then rose to a certain level, finally became stable.
