摘　　要：从涡街形成的机理出发,探讨涡街频率和流体体积流量间的内在关系,对基于涡街特性的流量测量的关键问题——旋涡发生体形状的选择、涡街信号检测方法、涡街信号分析及处理逐一进行分析,并在此基础上给出基于涡街特性的流量测量的研究方向。From the root cause of vortex formation, the intrinsic correlation between the vortex frequency and the fluid flux was discussed. The key issues of flow measurement based on vortex characteristics, such as the shape selection of vortex generator, the detection and analysis method of vortex signal, were analysed, and the research directions of the flow measurement based on the vortex characteristics were given.

关 键 词：涡街频率 流体流量 流量测量
