摘　　要：介绍应用几何溶液模型法预测三元系表面张力的新方法。由于引用了有理函数对所用的二元实验数据进行了优化处理,使计算精度大为提高。本方法用于Cu-Ag-Au体系后,所得结果与文献符合较好,说明这种处理方法是可行的。A new method for predicting the surface tension of ternary from biliary ones by using geometric solution model is given. Binary excess surface tensions are fitted by means of rational function method, and ternary excess surface tension are calculated using R-function method. That makes not only the calculaiton time to be less, but the results to be more accurate. This method was appliced to the Cu-Ag-Au system, and a good accordance was obtained between the calculated and reference values.
