摘　　要：水和水蒸汽物性参数的准确计算对核动力系统热工水力特性模拟是必不可少的．基于 IAPWS-IF97标准,开发了求解热物性参数(压力、热力学温度、比热容、比焓、比熵、比内能、比定压热客、比定容热容)、输运物性参数(导热系数、动力粘度)和表面张力的程序．其功能：给定饱和压力或者饱和温度求解饱和水、饱和蒸汽的其他物性参数；给定压力、温度求解水在各个区域的物性参数；给定压力、焓求解水在各个区域的物性参数以及给定任意2个参数求解其他物性参数．并将实例计算结果与上海发电设备成套设备研究所杨宇开发的物性参数计算程序的计算结果进行了比较,基本相同．Accurate calculation for properties of water and steam is necessary for thermal hydraulic characteristic simulation of nuclear power system. Based on IAPWS - IF97 stardard developes the program to calculate the thermal properties （pressure, temperature, specific volume, enthalpy, enthropy, inner energy, specific isobaric heat capacity, specific isochoric heat capacity）, transport properties（heat conductivity coefiScient, dynamic viscosity） and surface tension. The functions of program are： given saturation pressure or temperature, solves the properties of saturation water and steam; given pressure and temperature, solves the properties of water in every area; given pressure and enthalpy, solves the properties of water in every area; give any two parameters, solves the properties. Compares the results got by this program with the results got by program developed by Yang Yu, who works in Shanghai Generating Equipment Whole Equipment Institute, results are same.
