处理多元体系时，需其过剩热力学性质的表达式－ 用一个通式将六种常用的几何模型加以概括，估算了四个三元系的过剩摩尔体积，并与实验值作了比较，估算的误差小于０－０２ ｃｍ３·ｍｏｌ１－ 计算方法可适应不同的二元系表达式，并很容易扩展到多元系及其他热力学性质
Expression of Excess Thermothermic Properties in Multi-component Systems - Summarizing the six commonly used geometric models with one general formula, the excess molar volumes of the four ternary systems are estimated and compared with the experimental values. The estimated The error is less than 0-02 cm3 · mol -1 The calculation method can adapt to different binary system expressions and easily extend to multiple systems and other thermodynamic properties
