在针-板电极结构中，观察到水面上的脉冲正流光，间隙为20 mm。流光的传播特性进行了研究，通过使用ICCD相机。随外加电压的增加，流束沿径向传播，其传播距离增大。观察到了一个分支放电模式，通道直径为250-450 μ m。� 当针尖位于水面上时，流光从位于水面上方的针杆开始，然后到达水面，在水面上传播。
Pulsed positive streamers over the water surface were observed in the needle-to-plate electrode configuration with a gap of 20 mm. The characteristics of streamer propagation were investigated by using the ICCD camera. The filamentary streamers propagate in radial direction from the needle electrode and their progression distance increases with the increase of the applied voltage. A branching discharge pattern with the channel diameter of 250-450 �m was observed. � When the tip of the needle is set on the water surface, the streamers start from the needle stem located above the water surface and then reach the water surface, where they propagate on it.� The
