文中指出对于屏式过热器热力计算方法的修改是苏联73年标准与57年标准的主要区别之一。其修改的出发点是正确的,但某些修改内容值得商榷。本文从基本的热工原理出发,对73年标准中烟气对管壁的放热系数及屏的传热系数公式来源进行了探讨。1.对传热系数K=f(α_1.ε.α_2……)中的α_1、ε、α_2……在取用时必须明确它们是对取用怎样的受热面而言的,据查在73年 The article points out that the modification of the thermal calculation method of the screen superheater is one of the main differences between the 73-year standard and the 57-year standard of the Soviet Union. The starting point for its amendment is correct, but some of the changes worth discussing. Based on the basic principles of thermal engineering, this paper discusses the source of the heat transfer coefficient of the pipe wall and the heat transfer coefficient of the screen in the 73-year standard. 1. For the heat transfer coefficient K = f (α_1.ε.α_2 ......) in the α_1, ε, α_2 ... ... access in the use of them must be clear that the access to what kind of heating surface, it is investigated in 73 years
