摘　　要：通过对毛细管内等离子体工作过程的分析给出了电弧等离子体的一维非定常数学模型 ,以热力学参量描述了非理想条件下等离子体的状态方程和电导率计算方法。利用差分法求解该数学方程组 ,给出了毛细管内电弧等离子体特征参量在毛细管内沿轴向随时间的变化规律。对数值模拟结果作相应的分析 ,并将部分模拟结果与实验数据作了比较。An one-dimension time-dependent model of discharge plasma is presented paper by the analyzing of plasma behaviors in capillary. The state of equation and the electrical conductivity of non-ideal plasma are described in terms of thermodynamic characters. These coupled equations are solved by successive difference. The axial distributions along with time dependence of plasma characters in capillary are presented. The simulation results are compared and analyzed with experiment.
