电热加速器中毛细管高压放电特性分析

Analyses of characteristiocs for high pressure discharges in elecerothermaal accelerator

该文对毛细管受限高压放电的不同物理过程进行了描述。通过建立稳态径向通道模型、稳态一维模型、准稳态模型和瞬态集总模型，从不同的角度对毛细管受限高压放电的特性进行分析。并运用集总模型对不同参数的毛细管放电过程进行了计算比较，得到了一些毛细管特性规律。

Some models with respect to high pressure discharge in confined ablative capillary are given to describe the main physical characteristics in the process.By the radial steady model,axial steady model ,quasi steady and unsteady models presented here,some features of this kind of discharge are analyzed and confirmed by the numerical solutions combining with the published papers.Additionally the predictions of effect of the geometrical characteristics of the capillary on the plasma are also concerned in the developed lumped model.
