重复纳秒脉冲激发的大气压放电在各种应用中引起了极大的关注。本文采用重复频率纳秒脉冲发生器激励平板-平板放电。在不同的实验条件下，记录了外加电压、放电电流和放电图像。等离子体图像表明，放电模式随气流速度而变化，当气流速度大于35 m/s时，放电模式为弥散放电和均匀放电。气流的作用对两级脉冲放电产生不同的影响。第一脉冲电流在不同风速下基本保持一致。而第二次脉冲电流则呈现先减小后迅速增大的变化趋势，不同风量下第二次脉冲电流值相差约20 A。此外，根据电参数和放电图像对实验结果进行了讨论。
Atmospheric pressure discharges excited by repetitive nanosecond pulses have attracted significant attention for various applications. In this paper, a plate-plate discharge with airflows is excited by a repetitive nanosecond pulse generator. Under different experiment conditions, the applied voltages, discharge currents, and discharge images are recorded. The plasma images presented here indicate that the volume discharge modes vary with airflow speeds, and a diffuse and homogeneous volume discharge occurs at the speed of more than 35 m/s. The role of airflows provides different effects on the 2-stage pulse discharges. The 1st pulse currents nearly maintain consistency for different airflow speeds. However, the 2nd pulse current has a change trend of first decreasing and then rapidly increasing, and the value difference for 2nd pulse currents is about 20 A under different airflows. In addition, the experimental results are discussed according to the electrical parameters and discharge images.
