COMPUTER-AIDED COMPOSITION ANALYSIS FOR TERNARY MIXTURES

本文提出了一个计算机辅助三元体系组成分析方法。三元混合物的物理性质可从三个相应的二元体系用按比例内插法计算得到，借助于计算机分析三元体系物性与组成的关系获取三元体系的组成。本方法能有效地消除人为影响造成的误差，具有较高的精确度。只要某组分的某一物理性质与其它一个组分相差较大，一般不小于０．０７５，而不一定要求两条组成曲线之间很接近，也不要求相差较小的两组分间的组成曲线具有较好的线性。适应性强，应用范围较广。

A computer-aided composition analysis technique for ternary mixtures is proposed in this work. The physical property of ternary mixtures can be calculated from that of three corresponding binary mixtures by means of the proportional interpolation method. The ternary compositions can be obtained by analyzing the relationship of physical property and compositions for ternary mixtures with a computer.This technique could efficiently reduce the artificial errors and has high accuracy.It is only required that one physical property of one component is significantly different from that of another component,usually not less than 0.075,bu+ not that two composition curves are quite close to each other and composition curve of two closer components has good linearity.
