摘要: 热力学平衡的稳定性条件在经典热力学中具有重要的地位.本文从熵增加原理出发,先介绍了孤立均匀系统的热动平衡条件,再由熵的二阶导数小于零人手,结合热力学第一定律和麦氏关系导出了孤立均匀系统的平衡稳定性条件.
关键词: 孤立均匀系统, 熵增加原理, 热力学系统, 平衡稳定性条件
Abstract: Thermodynamic stability conditions of equilibrium play an important role in the classical thermodynamics. This paper starts with the principle of entropy increase and introduces the thermodynamic equilibrium condi- tions of isolated homogeneous system. Based on the second derivative of entropy less than zero and combining with the first law of thermodynamics and Maxwell relations, we educe the stability conditions of equilibrium for isolated homogeneous system.
Key words: isolated homogeneous system, principle of entropy increase, thermodynamic system, stability condi- tions of equilibrium
