计算物质热力学性质的基本依据是热状态方程和某些基本比热容对温度的依赖关系。等压比热容对压力的依赖性已经可以从这些关系式中推导出来。水和蒸汽性质的国际标准基于新的科学配方IAPWS-95。该方程是一个含有大量参数的亥姆霍兹无量纲函数形式。本文的目的是设计简单的等压比热容的水蒸气的压力和温度的范围内，在该范围内的蒸汽发生在大气中的湿空气的水蒸气的依赖。
The fundamental base for the calculation of the thermodynamic properties of substances is the thermal equation of state and the dependence of some of the basic specific heat capacities on temperature. Dependence of isobaric specific heat capacity on the pressure can already be deduced from these relations. International standards of the properties of water and steam are based on the new scientific formulation IAPWS-95. The equation is in the form of Helmholtz dimensionless function with very much parameters. The aim of this paper is to design the simple dependence of the isobaric specific heat capacity of water vapor on the pressure and temperature in the range in which the steam occurs in the atmospheric moist air.
