| 摘 要： | 本文求得了弹丸消融过程的自洽解析解。结果表明:Parks的弹丸消融理论需要修正;弹丸消融速率由消融物云和表面蒸发层共同控制;入射电子通过消融物云时慢化效应并不显著;消融物离开弹丸表面时一般呈部分电离态;聚变堆条件下,弹丸表面可能会出现激波。

| Abstract: | A self-consistent analytic solution to the solid pellet ablation in a high-terapreture plasma is obtained.It shows that the Parks' theory' needs modifyi ng.The ablation rate is controlled by both the ablation cloud and the vapori zing surface layer.The slowing-down effect of the ablation cloud on incident electrons is not considerable.The ablatant leaves the surface usually in partly-ionized state.And a shock will probably appear at the pellet surface under the fusion reactor plasma condition. |
