摘要:

根据微波和等离子的基本理论以及它们之间相互作用的原理，建立了由微波能、谐振腔内电场、工质流场、等离子体平衡场等组成的轴对称偏微分方程组。通过对模型的计算，获得了放电管内等离子体区的形状、电场、电子浓度和温度场，以及气体温度场。

Abstract:

The interaction between the microwave resonating in the resonance cavity and the plasma fluid in electric discharge tube is a very important problem for microwave plasma thruster(MPT).The axisymmetric partial differencial equations consisted of the microwave energy,the electrical field in resonance cavity,the medium flow field and the plasma equilibrium field were built according to the basic theories of microwave and plasma and the principle of the interaction between them.For the computation model the plasma region outline,the electric filed,the electron concentration and temperature fields and the gas temperature field in the electric discharge tube were obtained
