| 摘 要： | 为了获得超高速碰撞产生等离子体粒子密度的时空分布特性，利用点电荷电场的1维理论模型，综合运用质量守恒方程、动量守恒方程、能量守恒方程和麦克斯韦方程，推导出了等离子体在膨胀过程中粒子密度的时空分布规律。通过对超高速碰撞2024-T4铝靶实验采集的原始数据分析，得到了超高速碰撞2024-T4铝靶产生膨胀等离子体云粒子密度的时空演化规律。

| Abstract: | To acquire temporal and spatial distribution characteristics of particle density for plasma generated by hypervelocity impact, the paper synthetically considered the laws of mass conservation, momentum conservation, and energy conservation, and Maxwell equations. Temporal and spatial distribution of particle density was derived in expanding plasma cloud by using one-dimension theoretical model of field strength of point charge. The temporal and spatial evolution rules of particle density in expanding plasma cloud generated by hypervelocity impacting 2024-T4 aluminum targets were obtained based on the analysis of original data from 2024-T4 aluminum target impacting experiments. |
