| 摘 要： | 本文运用作者提出的从三个对应的二元系的热力学性质预示三元溶液的热力学性质的新对称几何模型,推导得到三元溶液中三个组元的偏摩尔热力学性质的数学表达式。进而将这一结果应用于NaCl-BaCl_2-SrCl_2三元熔盐相图的计算中,得到此三元系的液相析出面及若干等温截面。计算所得结果与实测结果偏差小于5℃,说明此模型在一些熔盐体系中有较好的适用性。

| Abstract: | The mathematical formulas are given for calculating the partial molarthermodynamic properties in a ternary system from its three corresponding binary sys-tems based on the new ternary symmetric model presented by the authors in theforegoing paper. Applying this model to NaCl-BaCl_2-SrCl_2 system, the phase diagramof which as well as some isothermal sections have been calculated. The deviations oftemperature between the calculated and experimental diagrams are less than five de-grees. |
