一般非理想Schlgl体系的相分离

Spinodal Decomposition in the General Nonideal Schlogl System

在Schlogl体系中,同时引入分子相互作用和分子体积两个非理想因素后,本文对相分离现象进行了讨论.分析表明,某些均匀定态可以分叉出相分离耗散结构分支.文中分别给出了第一分支点的参数值δ_μ.

The method in dealing with the general nonideal systems and the formula of calculating the activity coefficients are given.In Schlgl system, two nonideal factors, molecular interaction and molecular volume, are introduced simultaneously and more steady states are obtained.The stability of steady states is analyzed in details.
