摘　　要：化学热力学是物理化学的开篇内容和难点部分,学生在学习该部分内容的过程中,对热力学的一些基本概念如焓(H)、熵(S)以及它们的使用经常难以理解和想象。教学实践表明:利用Java小程序对热力学的一些概念和过程进行模拟或计算,可以将抽象的事物形象化,通过类似于"实验"的一些操作弥补单纯理论教学的不足,为热力学状态和相应热力学函数之间的关系提供一些实例。本文以理想气体状态变化、卡诺循环、盖斯定律、Gibbs自由能等四个例子来说明Java小程序在化学热力学教学中的应用。课堂教学过程中引入Java小程序,能提高学生的学习兴趣,深化对一些概念的理解,取得良好的教学效果。Chemical thermodynamics is the prelude of Physical Chemistry and also a difficult part.In teaching,some basic concepts like enthalpy or entropy and the application of them are quite difficult for students to imagine and understand.The application of java applet visualizes the values of Abstract properties during thermo-dynamic processes.And examples and experiments are provided to complementing theoretical derivations to show the relations between the thermo-dynamic state variables and energy forms in the context.In this paper ideal gas state change,carnot cyclic,Hess＇s law and gibbs free energy are introduced to show the application of java applet in teaching thermodynamics.The using of Java Applet not only improves the interest of students in learning but also helps students to understand and imagine some concepts.Good effect has been achieved.
