中文摘要：

实验研究了自然环境压力条件下等离子体发生器的脉冲放电特性。利用动态分压器和罗果夫斯基线圈型电流传感器测试了脉冲放电过程中消融毛细管等离子体的负载电压和放电电流。实验发现：在放电回路中使用钳位二极管可以有效地调整脉冲放电状态，提高等离子体发生器工作稳定性；调整放电回路的参数值也实现了回路的过阻尼放电，达到使用二极管整流的效果。

英文摘要：

The pulsed discharge properties of plasma generator are studied experimentally under natural environment. The load voltages and discharge currents of ablation plasma are recorded with dynamic divider and Rogowski current sensor. The clamp diode can adjust the discharge status efficiently, and the stability of plasma generator is enhanced. The adjustment of circuit parameters can also induce over-resistence discharge and realize the function of diode.
