混合流体浸润相变的研究(Ⅳ)——二元系统浸润相变的临界特性

STUDY ON WETTING TRANSITION IN A FLUID MIXTURE

本文研究了二元Sullivan流体在二相共存、三相共存时的临界指数。发现所得临界指数并不依赖于模型参量和动力学势的对称性,具有普适性,同时,这一组临界指数满足标度律。

The expression of critical exponents in wetting transition at two-phase and three-phase coex-istence in Sullivan mixture are studied, It is found that the critical exponents depend neither on the model parameters not on the symmetry of dynamical potential, i. e.: the exponents have universality.
