爱因斯坦固体在“熵和热力学第二定律”教学中的应用

Application of the Einstein Solid Model in the Teaching of Entropy and the Second Law of Thermodynamics

以M icrosoft Excel为计算工具,对爱因斯坦固体模型进行定量分析,以此引出熵的统计定义并将其与热力学第二定律联系起来,为熵和热力学第二定律的教学提供了一种较为有效的方法.与传统的从宏观热力学角度讨论熵的教学方法相比,这种方法显得更加具体直观.

The paper puts forwards an effective method for teaching entropy and the second law of thermodynamics with the Einstein solid model,in which the statistical definition of entropy is introduced through the quantitative analyses on the Einstein solid model by using Microsoft Excel.and then it is linked to the second law of thermodynamics.Compared with the traditional method,which discusses entropy from the perspective of macro-thermodynamics,the present method is more concrete.
