摘　　要：提出了一种测量管道流量的方法,即基于导热和对流和对流联合作用原理的中温管道流量测量方法。在提出测试原理的基础上,建立了依据该测试原理进行流量测量的实验台架,通过热空气等截面的实验试件进行实验。实验结果表明,基于导热和对流联合作用原理流量测量方法所依据的测试原理是正确的。由于该流量测量方法将流量测量问题转化为温度测量问题,因此产生误差的主要原因在于温度测量的准确度。A new method was proposed for flow measurement in medium_temperature pipe based on the theory of conduction and convection.On the basis of putting forward the theory, and the experimental equipment of flow measurement was built according to the experimental theory.The experiments were carried out by hot air flowing through the equal test section. The experimental result show that the theory of the flow measurement based on the theory of the conduction and the convection is accurate. The flows measurement was changed to the temperature measurement inthe method of the flow measurement, therefore the main reason of error is the preciseness of the temperature measurement.
