利用试验粒子Ｍｏｎｔｅ Ｃａｒｌｏ方法研究通过有限长旋转圆管的自由分子流。给出变量的归一化分布函数及由此进行随机抽样的方法。对研究通过静止圆管的自由分子流的方法进行改进，提出一种求通过旋转口管的自由分子流流量的方法．计算几种情况．并与无限长旋转圆管的解析结果作比较。主要结论如下：在管两端压差一定时，通过旋转国管的自由分子流流量随转速增加而减小；通过旋转口管的流量与通过静止圆管的流量的比值，随国管长度的增加而减小。
Experimental particle Monte Carlo method is used to study the free molecular flow through a finite length rotating cylinder. The normalized distribution function of variables and the method of random sampling are given. To improve the method of studying the free molecular flow through the still tube, a method of calculating the free molecular flow through the orifices is proposed. Calculate several situations. And compared with the analytical results of an infinitely long rotating cylinder. The main conclusions are as follows: When the pressure difference between the two ends of the tube is constant, the free molecular flow through the rotating tube decreases with the increase of the rotating speed. The ratio of the flow through the rotating tube to the flow through the stationary tube varies with the tube length Increase and decrease.
