水蒸汽热力状态参数数值计算方法的研究

A Research on the Calculation Method of the Numerical Value of the Parameters of Vapour in Thermodynamic State

本文运用最小二乘法建立满足一定精度要求的水蒸汽热力状态参数的数学表达式。这组公式为解决工程技术中有关水蒸汽热力状态参数数值计算问题提供了数学模型。

In this paper,a set of mathematical expressions,which can meet the requirements of acertain accuracy for the parameters of vapour in thermodynamic state,is established bymeans of least square,These expressions actually provide a mathematical model that can beused to solve the discussed calculation problems in engineering.
