摘　　要：以毛细管放电泵浦产生的 Ｃ 等离子体中，复合机制产生类 Ｈ Ｃ 离子 ３ｄ５／２ －２ｐ３／２跃迁激光线为例，研究毛细管放电复合 Ｘ 光激光中的物理机制。提出在 Ｃ 气中掺入适量的惰气来抑制等离子体被压得过细以至密度过高；在设计实验方案时，应该使等离子体在电流峰值之后进入膨胀冷却阶段；还要适当降低毛细管中等离子体初始密度以增大毛细管半径，使工艺上更容易实现。The physical scheme in 3d 5/2 2p 3/2 transition in H like C ion produced from Z pinch carbon plasma has been studied using a one dimensional Lagrangian MHD code coupled to an atomic kinetic code. The three phases, i.e., run in phase, stagnation thase and run out phase, were discussed, respectively. As results from discussion, C plasma should be intermingled with inert gas so that the electron density at stagnation isn't too high, the time when plasma enters into run out phase should be latter than the peak time of current, and the initial plasma density in the capillary should be low enough so that the required capillary radius is not too small.
