The surface potential build-up with constant current coronacharging for polypropylene electrets was investigated.
本文讨论了聚丙烯驻极体恒流电晕充电期间电荷的建立。

Experimental results and theoretical work show that the mechanisms of the direct charging and the coronacharging are respectively the tip effect and collision effect.
由试验结果和理论分析得到直接荷电法的机理是尖端效应，电晕荷电法的机理为碰撞荷电。

By neglecting the value change of the charge to mass ratio caused by the different pesticide solution, the coronacharging method was used with water solution replacing pesticide solution.
