| 摘 要： | 本文提出了沿垂直于流体流动方向激振流体，并在下游测量流体动量变化率，从而确定流体质量流量的一种新方法。对该方法进行了理论分析，并以气体为介质进行了实验研究，取得了与理论分析相一致的实验结果。所得结论为新型质量流量计的开发打下了良好的基础。

| Abstract: | A new method is presented in the paper. It measures fluid mass flow by vibratlng the fluid perpendicular to the flow direction and detecting the momentum rate- A theoretical analysis of the method is made, and a ser1es of experiments with alr flow is performed. Satisfied results in accordance with the theoretical analysis have been acqulred. The c0nclusions are very valuable to the development of a new type of mass flow meter. |
