本文介绍了一种测量真空泵转速的方法，它比现有的方法有许多优点。它可以在低至至少10-4 mm的压力下使用，并且与用于测量这些压力的压力计的校准的绝对精度无关。通过该方法的扩展，可以测量任何管道或其他通道的稀薄气体流动阻力，可以制作小比例模型。结果给出了直角弯管，T型件和其他组件，可能会被用于建设一个完整的真空系统。
A description is given of a method of measuring the speed of a vacuum pump which appears to have many advantages over existing methods. It can be used at pressures down to at least 10-4 mm and is independent of the absolute accuracy of the calibration of the gauge used to measure these pressures. By an extension of the method it becomes possible to measure the resistance to the flow of rarefied gas of any tube or other channel of which a small-scale model can be made. Results are given for right-angle bends, T-pieces and other components which are likely to be used in the construction of a complete vacuum system.
