大气压气体中的脉冲放电已被研究多年，因为它是去除有害环境污染物和产生臭氧的有前途的技术之一。特别是在文献中，一些研究人员报道了脉冲极性对污染物处理的影响。这些实验结果表明负脉冲放电提高了污染物气体处理的能量效率。描述了两种脉冲极性间流光传播机制的差异所引起的脉冲放电的极性效应。然而，目前尚未报道纳秒级脉冲放电极性效应的比较结果。本文对利用正纳秒脉冲放电和负纳秒脉冲放电产生臭氧进行了研究。实验中采用纳秒脉冲发生器，其输出脉冲电压的脉冲持续时间为5纳秒。结果表明，在高压施加下，负电压极性比正电压极性具有更高的臭氧产率。
Pulsed discharges in atmospheric pressure gases have been studied for many years since it is one of the promising technologies for the removal of the hazardous environmental pollutants and ozone generation. In the literatures, especially, some researchers reported that an effect of pulse polarity on pollutants treatment. These experimental results indicate that the negative pulsed discharge gives an improvement of an energy efficiency of pollutant gas treatment. It is described that the polarity effect of pulsed discharge caused by difference of streamer propagation mechanism between both pulse polarities. However, no comparison results of the polarity effect in nanoseconds range pulsed discharge has been reported so far. In this paper, an investigation of the ozone generation using positive and negative nano-seconds pulsed discharges was conducted. In the experiments, ns pulse generator which has 5 ns of pulse duration in output pulsed voltage is employed. The results showed negative voltage polarity has higher ozone production yield than positive one at high voltage application.
