摘 要：<正> A new model for predicting ternary thermodynamic properties from its three binary systems has been presented,that isEGm=(（X1X2）/(V12V21)EG12(V12V21)+(（X1X3）/(V13V31))EG13(V13,V31))+（1-X1）2 EG23（（X2/（1-X1））,（X3/1-X1））where EGm represents the ternary excess molar thermodynamic property; EGijindicates the thermodynamic properties of i-jbinary systems; Xi represents the mole fraction of component i of ternary solution,while Vii=（1+Xi-Xj）/2.The model is con-sidered to be rigorous in the case where the pseudobinary systems of fixed X2/X3 are regular solution.The application of newmodel to the prediction of ternary enthalpies of mixing for Bi-Ga-Sn,Au-Ag-Sn and NaCI-KCI-CaCl2 systems shows thatthe calculated results by new model are closer to experimental data than those by Toop’s model.
