Starting from the graphs of P-V and T-S and the second law of thermodynamics, and on different aspects and with different methods, this article studies the maximum value of the efficiency of heat engine in the process of arbitrary cycles, and presents the conclusion that the efficiency of the heat engine in Carnot cycle is the greatest among all arbitrary cycles.

卡诺定理给出了热机的循环效率极大值问题。由P-V图、T-S图、热力学第二定律出发，从不同的角度，采用不同的方法，对任意循环过程的热机效率极大值问题进行了研究，证明了任意循环过程热机效率以卡诺循环的热机效率为最大极限值的结论

Firstly, according to the relationship between classic Carnot cycle and Lorenz cycle, the paper evaluates the cycle characteristics and thermodynamic properties of NARMS (Non-azeotropic mixtures), and compares the energy-saving difference between pure and mixed refrigerants. The main of factors that affect heat pump operating efficiency are analyzed in theory and using the Second Law of Thermodynamics the exergy are evaluated in components of heat pump system, in the end a conclusion is drew that all of the exergy have bearing on working fluids' properties.

本文首先从经典的Carnot逆循环与Lorenz逆循环相对关系出发，评估了非共沸混合工质循环的特点以及热力学性质；在不同环境条件下，比较了单工质与混合工质的循环特性差异；针对非共沸混合工质热泵循环效率的主要影响因素（即工质本身的热物性和系统部件特性）进行了理论分析，并利用热力学第二定律对热泵系统的各个主要部件进行了可用能分析，最终发现每一处可用能损失均与工质物性有关；在此基础上提出了减少可用能损失的方法—寻找适宜的非共沸混合工质。
