The changing law of retention index with temperature from chromatographic thermal function resulted from the variation of the different entropy and enthalpy during the chromatographic separation.
Expressions of entropy, enthalpy and Gibbs function are formulated by exterior differential derived from second law of thermodynamics.
从热力学第二定理出发，利用外微分构造了熵、焓以及吉布斯函数的表达式。

Based on the theory of radial distribution function, a new unified model for excess enthalpy and excess Gibbs free energy of liquid solution was proposed.
