微观量的估算问题是热学中的主要问题之一,但由于组成物质的分子很小,且分子的分布排列因不同的物态,有着很大的差异,所以要研究分子的有关情况就必须建立一定的物理模型.下面介绍热学中的几个常见模型,供同学们学习参考. The estimation of microscopic quantities is one of the major problems in thermal science. However, because the molecules of the constituent materials are small and the distribution of molecules is different due to different states of matter, there are great differences. Therefore, it is necessary to establish the situation of the molecules to be studied. A certain physical model. Here are some common models in thermals for students to learn.
