    氣體(ti)(ti)的(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程 ：在通常情(qing)況下氣體(ti)(ti)是不導電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)，但(dan)在高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)作用(yong)下氣體(ti)(ti)內部的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子便會獲得足夠的(de)(de)能量成為自由電(dian)(dian)(dian)(dian)(dian)(dian)子而導電(dian)(dian)(dian)(dian)(dian)(dian)，被(bei)稱為自發性電(dian)(dian)(dian)(dian)(dian)(dian)離現象。氣體(ti)(ti)的(de)(de)自發性電(dian)(dian)(dian)(dian)(dian)(dian)離是建(jian)立在非(fei)(fei)均(jun)勻(yun)性電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)中(zhong)。在均(jun)勻(yun)性電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)中(zhong)，隨著(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)增加，只要其(qi)間任何一(yi)點發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，兩極間將立即充滿帶電(dian)(dian)(dian)(dian)(dian)(dian)離子，整個空間的(de)(de)氣體(ti)(ti)被(bei)擊穿。此時電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)急劇增加而形成火(huo)花(hua)放電(dian)(dian)(dian)(dian)(dian)(dian)。而在非(fei)(fei)均(jun)勻(yun)性電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)強度則隨兩極間的(de)(de)距(ju)離增大而迅速下降。

    工業(ye)中的(de)選(xuan)擇(ze) ：根(gen)據供電(dian)(dian)極性的(de)不(bu)同，電(dian)(dian)暈(yun)有陰電(dian)(dian)暈(yun)和(he)陽(yang)(yang)電(dian)(dian)暈(yun)之分(fen)。在工業(ye)生(sheng)產中，大多采(cai)用陰電(dian)(dian)暈(yun)，因為在相同的(de)條(tiao)件(jian)下，陰電(dian)(dian)暈(yun)可以獲得比(bi)陽(yang)(yang)電(dian)(dian)暈(yun)高的(de)電(dian)(dian)流，而且其(qi)閃絡(luo)電(dian)(dian)壓也遠比(bi)陽(yang)(yang)電(dian)(dian)暈(yun)放電(dian)(dian)要高。
