| 摘 要： | 利用ns级时间分辨可见光分幅相机和光纤传感器对“强光一号”环-板型水介质开关进行光学测量，得到了电流通道发展图像以及整个放电过程的光强变化信号。实验结果表明:环-板型水介质开关开始击穿时的平均场强约为190 kV/cm，同时存在多个放电通道，流注呈树枝状分布，发展速度为几十cm/ms。

| Abstract: | The optical diagnostics of annulus-flat water switch in “Qiangguang-Ⅰ” facility was carried out utilizing optical framing camera and fiber sensor. The images of the discharging channels and the irradiance intensity signal during charging stage were acquired. The experiment results showed that the average breakdown electric field of annulus-flat water switch was about 190 kV/cm, several discharging channels were observed at the same time, the streamers appeared like bush and their velocity was about tens of cm/μs. |
