摘　　要：在不同的电压和电导率参数条件下分类实验研究了水中脉冲放电的两种方式 (电弧放电和电晕放电 ) ,采集并分析了实验中的电压和电流数据。然后简要讨论了两种放电方式的产生机理 (与电弧方式的热过程机理相比 ,电晕方式的初始机理还很不清楚 )。最后从实验现象、产生机理和应用前景等方面对比分析了两种放电方式。实验发现在大的溶液电导率下水中电晕放电方式的声学效应明显 ,为水下等离子体声源的设计提供了新的思路。The experiment of two types of underwater pulsed discharge-arc discharge and corona discharge, have been carried out, under different varying voltages and solution conductivities. Then the voltage and current data in the experiment have been collected and analyzed. The initiation mechanisms of two different types of underwater discharge have been discussed briefly. Compared to the thermal mechanism of arc discharge, the initiation mechanism of the corona discharge is too unclear. Finally, several aspects of two different types of discharge have been compared and analyzed from experiment phenomena, initiation mechanisms to application prospects. It has been shown that the underwater pulsed corona discharge can generate the apparent acoustical effect when the solution conductivity is high enough. According to this acoustical effect, a new underwater plasma source could be designed.
