在许多领域中已经开发了使用脉冲功率技术的工业应用。其中之一是通过使用均匀产生的流光放电来处理废气。液体中的流光放电也会在流光的尖端产生极高的电场，以及高能电子、臭氧、其他化学活性物质、紫外线和冲击波。所有这些都可以用来杀灭微生物和分解分子和材料。为了实现工业应用，已经产生了水中的大体积流光放电。已经使用线到平面电极配置。在水中的放电显示类似的光辐射，在大气中的气体提供的证据，从静止的照片。讨论了极性、电导率、电极几何形状和静水压力对液体中流光的影响、流光放电的机理以及流光在液体中可能的工业应用。
Industrial applications using pulsed power technologies have been developed in many fields. One of them is the treatment of exhaust gas by using uniformly produced streamer discharges. Streamer discharges in liquid also generate extremely high electric fields at the tip of streamers, as well as high energy electrons, ozone, other chemically active species, ultraviolet rays and shock waves. All of these may be utilized to sterilize microorganisms and to decompose molecules and materials. Large-volume streamer discharges in water have been produced in order to realize industrial applications. A wire to plane electrode configuration has been used. The discharge in water shows similar optical radiation to that in an atmospheric gas as provided by evidence from still photographs. The influence of polarity, conductivity, electrode geometry and hydrostatic pressure on the streamers in liquid, the mechanism of streamer discharges and possible industrial applications of streamers in liquids, are discussed in the present work.
