| 摘 要： | 使用上升沿40 ns、脉宽70 ns的重复频率单极性纳秒脉冲电源，采用双水电极结构产生大气压空气中介质阻挡放电。测量了纳秒脉冲下介质阻挡电压和电流，并获得长曝光时间和ns级曝光时间的放电特性，采用曝光时间为2 ns的高速摄影拍摄放电发展过程。结果表明:大气压空气中，水电极结构纳秒脉冲介质阻挡放电能够产生稳定均匀的放电等离子体，且存在二次放电。高速摄影对放电发展过程的拍摄结果表明:放电首先由电极中部开始发展，径向扩展至整个电极范围。

| Abstract: | The dielectric barrier discharge (DBD) at one atmospheric pressure is excitated in a configuration of two water electrodes by a repetitive nanosecond-pulse generator with 40 ns rise time and 70 ns duration. The DBD characteristic is studied by the measurement of DBD voltage and current, DBD images of long and nanosecond exposures. Especially, the discharge images taken by ICCD with 2 ns exposure time are used to study the temporal behaviour of the discharge development. The results indicate that the nanosecond-pulse discharge is uniform and stable with the water electrodes in atmospheric air and there is a secondary discharge. The homogeneous discharge starts from the central part of the discharge area and spreads radially outward. |
