摘要

本文基于热力学第一、二定律及麦克斯韦关系,系统讨论了橡皮筋的热力学性质,并简单介绍了橡皮筋弹性的微观模型.与传统热学教学中以理想气体为例相比,这些方法与结论既有利于学生理解与掌握热力学基本知识与研究方法,又有利于学生自主设计实验去验证这些结论的正确性.

Abstract

 Based on the first and second laws of thermodynamics and Maxwell relation, the thermodynamic properties of the rubber bands are systematically discussed. We also briefly introduce the micro-model of the rubber band elasticity. These methods and conclusions will help students to better understand and master the basic knowledge and methods of thermodynamics, and also avail students to test the correctness of these conclusions by the experiments designed by themselves
