热力学状态函数关系式的图例及例证分析

A Diagram and the Examples of Thermodynamical Equations

热力学状态和状态函数是物理化学热力学中重要的概念,状态函数之间的数学关系所构成的基本公式非常多且繁杂.借助于一个简单的图例把状态函数有机的联系起来,很好地揭示了它们之间内在的各种变换关系.此图可以帮助学生在学习过程中加强记忆和理解,在物理化学教学中值得推广和应用.

Thermodynamic state and state function are important concepts in thermodynamics of physical chemistry. The basic equations, which derive from the mathematical relation among state functions, are multiple and complex. By aided of a simple diagram, all kinds of transformation relations among state functions are clearly elucidated. This diagram is worth popularizing and applying in physical chemistry teaching, which can help students strengthening their memory and understanding during the process of learning thermodynamics function.
