【摘要】 本文提出了一个由二元系推算三元系热力学性质的新模型，此模型能自动用热力学准则来检查各二元系的对称性，并根据不对称程度来构筑权重函数，由于不需要事先选择不对称组元，消除了计算过程中的人为干扰．此模型逐点比较二元系的相似性，当体系中有的二元系模型仅在局部浓度范围有效时，仍能合理地运用，和目前已有的一般化几何模型相比，此模型的适用范围有所拓宽．更多还原

【Abstract】 A new geometric model for predicting ternary thermodynamic properties from binaries is suggested. The model quantifies the asymmetric degree of the system with an exponent weight function according to the thermodynamic criterion, so as to avoid human interferences of choosing asymmetric component. It compares the similarity between every pair of binaries point by point, so that it can be applied to the system where the binary models do not cover the whole domains of compositions.更多还原
