摘　　要：为了模拟稀薄等离子体超音速稳态流动,建立了PIC/DSMC混和方法模型.以稳态等离子体推力器(SPT-70)为对象,进行了数值模拟.输入条件来自在真空舱内对SPT-70的实验测量和相关性能计算,数值结果与实验结果的比较表明:本文建立的数学模型和编制的软件是可信的,可以为电推力器性能评价及潜在的羽流污染评估提供有效途径.A hybrid PIC/DSMC method was developed to simulate the steady flow of rarefied plasma. The stationary plasma thruster （SPT-70） was established and used to experiment in vacuum cabin. The parameters that are used to numerical simulation were obtained by a double Langmuir probe and interrelated calculations. The numerical results agree with those gained by experiments. It is shown the model and code developed here are believable.
