摘　　要：热力学与统计物理学理论性强、公式繁多,麦克斯韦关系作为不可测量量与可测量量的桥梁,是热力学中的重要关系式,涉及封闭系统和开放系统共16个等式,容易混淆。通过对结构极其相似的关系式中各物理量位置规律进行研究,提出简单记忆的方法,减轻学生对众多等式记忆的难度,方便掌握和灵活使用。Thermodynamics and statistical physics are highly theoretical with many formulas.The Maxwell relationship,as a bridge between unmeasurable and measurable quantities,is an important relation equation in thermodynamics,involving a total of 16 equations for both closed and open systems,and is easily confused.Through the study of the position law of physical variables in relation equations with extremely similar structures,a simple memorization method was proposed to ease students’difficulty in memorizing numerous equations and to facilitate their mastery and flexible use.

关 键 词：热力学函数 麦克斯韦关系 位置规律
