摘　　要：分析了HAT循环和STIG循环中的工质 -湿燃气的组成 ;将湿燃气当做实际气体考虑 ,用两项维里方程的对比态形式建立了湿燃气的状态方程 ;利用状态方程和余函数修正法 ,对湿燃气的热力性质在理想气体的基础上进行了修正 ,使其热力性质较按理想气体计算时更加精确 .该算法可以计算湿燃气在任意烃类燃料、任意注蒸汽比以及任意燃料系数条件下的热力性质 .The working fluid during HAT and STIG cycles is referred to as 'moist combustion gas' and it contains a large amount of steam and is considered as a real gas in this thesis. The state equation has been established for the moist combustion gas as a two terms Virial equation. With the aid of the state equation and the deviation function, the thermodynamic properties of moist combustion gas can be calculated accurately. The method can be used to calculate the thermodynamic properties of the moist combustion gas for any kind of hydrocarbon fuel, any steam injection ratio and any fuel coefficient.
