摘要

由于电极/液界面处的电荷注入，碳酸丙烯酯的电压/电流特性在100 kV/cm以上呈指数上升。研究了减少这种注入的可能方法，并给出了实验结果。消除注入电流是在静电机器中使用高介电常数液体(如碳酸丙烯酯)作为流体介质的必要条件。大量的实验表明了场致钝化的可能性。

Abatement of injection currents in propylene carbonate

The voltage/current characteristic in propylene carbonate shows an exponential rise of current above 100 kV/cm, due to charge injection at the electrode/liquid interface. Possible means to abate this injection were investigated, and experimental results are presented. Abatement of injection currents is an essential condition for the use of high-permittivity liquids (e.g., propylene carbonate) as fluid dielectrics in electrostatic machines. A large number of experimental series have been performed which show the possibility of field-induced passivation.<>
