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。 This paper describes the different physical processes of capillary restricted high-voltage discharge. Through the establishment of steady-state radial channel model, steady-state one-dimensional model, quasi-steady state model and transient lumped model, from different angles of capillary high-voltage discharge characteristics of the analysis. And using the lumped model for different parameters of the capillary discharge process were calculated and compared, and some capillary properties of the law.
