摘　　要：热力学关系式包括大量的复杂微分方程式.这些关系式十分相似,容易混淆,给准确记忆和正确使用带来了诸多不便.为帮助研究人员更好地掌握和运用这些关系式,首先利用各热力学参数构建了一种简单的记忆图表,然后介绍了运用该图表快速列写出热力学基本关系式、麦克斯韦方程式及八个一阶偏微分方程的规则.这种记忆法使用方便,能同时记住热力学各种微分关系式且简单易懂、记忆准确.利用这种记忆方法可以避免产生混乱,减轻记忆工作量,提高学习和运用热力学一般关系式的效率.A large number of complex equations are included in the thermodynamic relations.These equations are so similar that they are difficult to be remembered and easy to be confused.To help researchers mastering and using these relations better,we give out a mnemonic diagram based on thermodynamic parameters,then use the rules of this diagram to get the basic relations of Thermodynamics,the Maxwell＇s relations and eight first-order partial differential equations.This mnemonic method is simple,practical and efficient.With this method,confusion can be avoided,memory load can be reduced,and efficiency of studying and using the thermodynamics relations can be increased.
