摘　　要：Atmospheric pressure discharges excited by repetitive nanosecond pulses have at- tracted 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 con- ditions, 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, anda 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 cur- rents is about 20 A under different airflows. In addition, the experimental results are discussed according to the electrical parameters and discharge images.Atmospheric pressure discharges excited by repetitive nanosecond pulses have at- tracted significant attention for various applications.
