利用可消融材料制成毛细管，在其两端阳极与中空阴极间进行大功率放电，形成高压等离子体源．这种技术可应用于电热／电热化学超高速推进技术．本文在处理这类问题的时间相关两维统一模型基础上，针对狭长毛细管及径向快速松驰条件，运用积分平均方法，建立了能反映这一物理过程主要特征的时间相关轴向一维模型．计算表明：本文所建模型与计算方法能正确再现受限毛细管高压放电的主要物理过程，计算结果得到了实验验证
Capillary made of ablatable material, high-power discharge between the anode and the hollow cathode at both ends of the capillaries to form a high-pressure plasma source. This technology can be applied to electrothermal / electrothermal chemical super-high-speed propulsion technology. Based on the time-dependent two-dimensional unified model of this kind of problem, this paper established a time-dependent axial one-dimensional model that can reflect the main features of the physical process for long narrow capillaries and radial rapid relaxation conditions by using the integral averaging method . The calculation shows that the model and calculation method proposed in this paper can reproduce the main physical processes of high-voltage discharge with limited capillary, and the calculation results are verified by experiments
