摘　　要：通过讨论热力学熵与热力学第二定律、能之间的关系,说明了熵不仅是能量的一种形式,又是热力学状态函数.并对热力学熵与波尔兹曼熵的不同论述进行了分析.通过热力学基本关系式和状态函数关系式的分析,指出了热力学熵与其它状态函数的区别,说明了热力学熵不仅是状态函数,而且也是热力学的状态参数.The result of the discussion of the relations between the thermodynamic entropy and the second law of thermodynamics shows that entropy is not only a form of energy,but also a thermodynamic state function.Through the analysis of the basic thermodynamic relationship and the state function,the difference between the thermodynamic entropy and other state function is described.This paper attempts to demonstrate that the thermodynamic entropy is not only a state function,but also a parameter of the thermodynamic state.
