摘　　要：提出了一种基于传热原理高温蒸汽流量测量的新方法,分析了测试原理的可行性,并建立了依据该测试原理进行流量测量的实验台。实验结果表明,基于传热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,因此测量误差主要取决于温度测量的准确度。A new method of flow measurement based on the theory of heat transfer is described. On the basis of putting forward the experimental theory, the feasibility of experimental theory is analyzed, and the experimental equipment of flow measurement is developed according to the experimental theory. The experimental result shows that the theory of flow measurement based on heat transfer is accurate. The accuracy is dependent on the precision of temperature measurement because flow measurement is changed to temperature measurement in the method.
