通过使用数值模拟和实验相结合的方法研究圆柱形霍尔等离子体推进器。应用蒙特卡洛方法和Particle In Cell (PIC)方法对放电通道内等离子体碰撞和行为进行模拟。建立圆柱形霍尔推进器的物理和数值模型；通过对放电和加速区等离子体的产生和输运进行模拟，掌握了等离子体放电和加速机理以及内磁极的刻蚀情况。结果表明：随着电压的升高，内磁极刻蚀较为严重；推进器内部离子能量值约为放电电压值的50%左右。同时通过实验方法测定不同放电电压情况下推进器的放电性能。

A method combining the numerical simulation and experiment is used to research the cylindrical anode layer hall plasma thruster. Use the method of Monte Carlo method and particle in cell (PIC) was used to simulate the collision and the behavior of plasma in discharge channel, then the physical and numerical model of cylindrical hall accelerator was set up. By simulating the producing and transporting of plasma in discharge area and accelerate area, the mechanism of discharge and accelerate of plasma, and the etching of the pole were obtained. The result shows that, with the increasing of voltage, the etching of inner pole become more serious;the ion energy value in the thruster is about 50% of the discharge voltage value. Meanwhile, measurement of discharge property of thruster in different discharge voltage is also done by experimental method.
