回顾了水和水蒸汽热力学性质的通用计算方法，比较了国际上影响较大的几种模型，并在此基础上探讨了使用ＩＦＣ模型建立水和水蒸汽通用计算软件包所涉及的变量组合，一维、二维非线性方程迭代算法及针对水和水蒸气计算模型的特点实现变量分离以期提高计算速度等问题。还介绍了“水和水蒸汽热力性质的ＩＦＣ公式通用计算软件包”的使用及其在线调用库函数的有关情况。
The general calculation method of the thermodynamic properties of water and steam is reviewed. Several models which are more influential in the world are compared. On the basis of this, the variables combinations involved in establishing general software packages for water and steam using the IFC model are discussed. One-dimensional, two-dimensional nonlinear equations iterative algorithm and water and steam calculation model for the characteristics of variables to achieve the purpose of improving the calculation speed and other issues. The article also introduces the usage of “General Calculation Software Package for IFC Formulas for Thermodynamic Properties of Water and Steam” and its online call library functions.
