摘要：

A technique has been developed to provide a close estimate of the equilibrium composition in multiphase multicomponent systems. Both the standard Gibbs energies of species and mass constraints are considered in this computation. The estimates accelerate the rate of convergence of more general Gibbs energy minimization methods and are useful in predicting stoichiometric reactions. Special situations where the output may be taken as the final solution are discussed. These include the computation of multielement stability diagrams involving stoichiometric phases.
