利用高速ＣＣＤ相机拍摄了ＨＬ－１Ｍ等离子体中注入氢弹丸时的Ｈα辐射照片。得到的弹丸不同形状消融云照片表明：弹丸轨迹发生弯曲和出现条纹。通过对照片的处理获得了辐射光强的空间分布、弹丸的速度与轨迹，分析了弹丸与等离子体相互作用的物理机制，为进一步在弹丸注入条件下用ＣＣＤ测量等离子体局部磁场和电流分布打下了基础 High-speed CCD camera was used to photograph the Hα radiation in hydrogen plasma injected into HL-1M plasma. The projectile obtained from different shapes of ablation cloud photos shows that the trajectory of the projectile is bent and streaked. The spatial distribution of radiation intensity and the velocity and trajectory of the projectile were obtained by processing the photos. The physical mechanism of the interaction between the projectile and the plasma was analyzed. In order to further test the local magnetic field and current distribution of the plasma measured by the CCD with projectile injection The foundation
