在电气回路上如不清楚或不明确线路之极性时，则建议使用无极性电解电容器。
If circuit polarity is unclear or unknown, then non-polar capacitors is recommended.
荷电电极接电源不同极性时荷电效果亦不同，接电源负极所能够达到的最大荷质比较大。
Experiment is performed and the result shows that the sharp electrode is the best and power supply should connect the negative pole.
放电间隙较大的静止状态下，直流电压正极性和交流电压下气固混合两相体的击穿电压都大于相同条件下单一空气的，而直流电压负极性时则相反。
In the in- active state, the breakdown voltage were higher than the single air in the same conditions under AC and positive DC voltage, but it was opposite under negative DC voltage.
