本文系介绍运用热力学基础理论和高等数学推导得过热水蒸汽比焓等函数的新公式,全文已刊于1989年1月《中国电机工程学报》。由于该新公式计算简便、适用范围扩大,且对于新国际骨架表有足够的精度。本刊现摘录其中结论部分(推导过程从略)介绍给读者,便于工程实用。 This article describes the use of basic theory of thermodynamics and higher mathematics derive the new formula of the specific enthalpy of superheated water vapor and other functions, the full text has been published in January 1989, “China Electrical Engineering Society.” Due to the simple calculation of the new formula, the scope of application has been expanded and sufficient accuracy has been obtained for the new international framework table. The magazine excerpts which conclusions (derivation process omitted) introduced to the reader, easy to use engineering.
