摘　　要：以PR状态方程、逸度系数方程、混合法则、相平衡方程组为基础,求解出混合工质特定压力下的泡点温度和露点温度,从而绘制出二元混合工质在特定压力下的气液相平衡图。分析了二元混合工质的露点温度或泡点温度与工质的种类、配比、压力之间的关系。以选取适合脉动热管传热特性的二元混合工质热力参数为例,得到选取混合工质的相应方法及注意事项。Based on the state equation PR equation of state, fugacity coefficient equation, mixing rule equation and equilibrium equations for the program, the bubble point tequilibrium diagram is drew. According to calculations, the focuses on the bubble point temperature and dew point temperature which are kinds of mixture, ratio of composition and pressure are analyzed. In order to select the appropriate thermodynamic parameters of binary mixture for the pulsating heat pipe, the paper showed the methods and precautions corresponding selecting mixed refrigerants.
