| 摘 要： | 本文提出一种预示三元系热力学性质和用于相图计算的新几何不对称模型，该模型在现有不对称模型中数学解析式最简洁，计算精度较高，它应用于Bi-Ga-Sn,Au-Ag-Sn和NaCl-KCl-CaCl2 3个三元系，计算值与实验结果吻合较好，文中还阐明了在不对称模型中选取不对称组元的热力学准则。

| Abstract: | A new geometric asymmetric model for predicting t thermodynamic properties of ternary system from three sub-binaries is presented. Its analytical expression with good calculating accuracy is most simple in present asymmetric models. The new model was applied to predict the enthalpies of mixing of the Bi-Ga-Sn, Au-Ag-Sn and NaCl-KC1-CaCl2 ternary systems which were in good agreements with experimental data. At present work, based on thermodynamic principles, the importance of the choice of symmetric component is also discussed. |
