摘　　要：介绍了几种不同节流装置（即流量计）的结构特点、在风洞中的校准方法、校准结果以及对结果的应用，并对几种节流装置的流体动力特性作了分析，结果表明，在几种节流装置中，除翼型节流装置外，流量测量精度较高的节流装置的压力损失系数较大。The structure of several differential throttling equipment （viz. flowmeter）, calibrating method in wind tunnel, calibrating results and applied on results were briefly described. The fluid dynamic character of differential throttling equipment was analysed, the results had been shown, the higher accuracy of the flow measure, the greater pressure penalty in differential throttling equipment except airfoil type.
