说明：  本软件根据“水和蒸汽热力学性质的工业公式1997”（IAPWS-IF97）编写，计算结果与《水和蒸汽的性质》——W.瓦格纳著一书中附表基本一致。 软件正函数(已知压力温度求其它值)的主体部分由中山大学张冰剑完成，中国石化节能技术服务中心叶剑云在此基础上增加了闪蒸、汽轮机计算以及反函数迭代计算部分。
(The software according to the water and steam thermodynamic properties of 1997 industrial formula (iapws-if97), the calculation results with the properties of water and steam- w. Wagner the book table. Software is function (pressure and temperature and other known value) completed by bing-jian zhang of zhongshan university, in the main body of China petrochemical Ye Jianyun energy-saving technical service center on the basis of increased the flash, the calculation of turbine, and the proportion of the inverse function iteration calculation.)
