The results show that the variation trend of ADF with polishing time is flat-steep-flat; the variation of surface roughness results in the different distri- butions of surface current density, and there is a fine surface smoothness in the special period of ECP from 4 to 8 s.展开更多

The results show that the variation features of ADF with polishing time are fiat-steep-fiat, and the variation features of A CF with polishing time are random-regular-random. There is a fine surface smoothness at the special period of ECP. Both the original surface and the full ECP surface show an obvious roughness.展开更多
