摘要:

对两种界面热力学处理方法(古根海姆法与吉布斯法)进行了介绍。采用吉布斯界面热力学方法建立了存在界面相时两相平衡的热力学判据,并以此为基础提出了一种新的开尔文方程推导方法。

关键词: 开尔文方程, 古根海姆界面热力学, 吉布斯界面热力学

Abstract:

In this paper, two interface thermodynamics methods, the Guggenheim method and the Gibbs method, are introduced.The thermodynamic criterion of the two-phase equilibrium is established using Gibbs interface thermodynamics, and a new method for derivation of Kelvin equation is put forward based on the thermodynamic criterion of the two-phase equilibrium.

Key words: Kelvin Equation, Guggenheim interface thermodynamics, Gibbs interface thermodynamics
