关 键 词：closed net invariant point multisystem phase diagram the absent phase substitution method
摘 要：A new convenient combinatorial method is developed here to derive the invariant points in multisystem closed nets - the absent phase substitution(APS) *** substantially simplifies the derivation of the closed nets in multisystems with many components and *** the multisystems whose total phase number(N)≤twice the number of the absent phases(m) in an invariant assemblage,the method can yield regular closed nets with or without globally absent phases;for other multisystems,the method can yield the regular closed nets with globally absent *** examples,the APS method was used to predict:(1) the regular closed nets of unary to quinary n + 4-phase multisystems,unary 6-phase multisystem and ternary 8-phase multisystem;(2) the basic properties of the regular closed nets of the quaternary and quinary multisystems with n + 4 and n + 5 *** multisystems were chosen to demonstrate how to select a realistic closed net from the numerous possible closed nets of a complex multisystem,and how to derive a realistic partially closed-net,closed-net-diagram and the related realistic *** of our APS method for the derivation of complicated closed nets with other methods indicate that this method is much simpler and more efficient.
