| 中文摘要:为进一步了解大气压气液纳秒脉冲放电的电气特性，自行研制喷嘴 板 筒式反应器，研究纳秒负脉冲气液两相放电中喷嘴电极与接地板 筒电极间距、鼓气流量、喷嘴直径、脉冲重复频率和放电时间等对起始放电电压、电流波形的影响。结果表明：起始放电电压的主要影响因素为两极间距；不同鼓气流量对起始放电发生的影响可能表现为抑制或促进；起始放电电压、电流绝对值随着脉冲重复频率的增加而略有上升。实验中水溶液电导率随放电持续时间延长而增大，表明活性粒子数量增加。 |

| Abstract: In order to learn more about the electrical characteristics of gas liquid nano second pulsed discharge at the atmospheric pressure, the self developed reactor with the nozzle plate cylinder electrode is adopted. The effects of the distance between the nozzle electrode and the ground plate cylinder electrode, the gas flow, the diameter of the nozzle，the pulsed repetition frequency and the duration time of the discharge on the onset discharge voltage and current wave forms are investigated in the nano second negative pulse gas liquid two phase discharge. The results show that the effect of the distance between the twoelectrodes on the onset discharge voltage is important, the effect of different gas flow on the occurrence of onset discharge may be inhibited or promoted, and the absolute values of the onset discharge voltage and current increase slightly with the increase of the pulse repetition frequency. In the experiment, the electrical conductivity of aqueous solution increases with the duration time of discharge, indicating that the number of active particles increases. |
