几何模型的统计法评价及在有机体系的应用

Estimation of excess thermodynamic property of ternary non electrolyte solution

用丰富的实验数据经统计的方法对常用的几种用于三元溶液热力学性质估算的几何模型进行比较和评价，以选择合理的适用于冶金熔体的计算模型－ 新一代几何模型不但适用于冶金熔体热力学性质的计算。

The excess thermodynamic property is often needed when dealing with more than two components system.A general formula is presented interconnecting six current geometric model for predicting excess properties of milticomponentt system.Excess molar volume of four ternary non electrolyte solution is estimated and compared with the experimental data.The estimation error is lower than 0.02 cm 3 mol 1 .Furthermore,other properties of multicomponent can be estimated with the method based on any kinds of expression of binaries.
