| 摘 要： | 叙述了高速摄影在阳加速器喷气Z-pinch实验中测量等离子体向心运动时的应用，用高速变像管扫描相机首次拍摄到阳加速器喷气负载为氖气状态下产生等离子体压缩过程的扫描像，该扫描像的时间分辨本领很高,可以观察到等离子体内爆压缩阶段整个过程，测得了该过程的直径随时间连续变化曲线。

| Abstract: | This paper stated applying method for high speed photography to study centripetal motion plasma generated by gas-puff Z-pinch internal explosion on anode accelerator. The scanning images with high temporal resolution of plasma pinching generated by anode accelerator applying Neon as gas-puff load, was obtained using image-converter streak camera. The process of plasma internal explosion pinching was observed, and the curves of plasma pinching diameter corresponding to scanning time were given. |
