本文提出了一种计算稀薄气体在任意压力和温度降作用下通过变半径长管的质量流量的方法。该方法是基于先前获得的动力学方程的基础上的结果，它需要非常温和的计算工作。文中给出了等温流动和非等温流动的一些例子，以说明其应用。还考虑了变半径管的热分子压差。
A method to calculate a mass flow rate of rarefied gas through a long tube of variable radius subject to arbitrary drops of pressure and temperature is proposed. The method is based on the results obtained previously on the basis of the kinetic equation and it requires very modest computational efforts. As a demonstration of its application some examples of isothermal and nonisothermal flows are given. The thermomolecular pressure difference for a variable radius tube is also considered.
