摘要
文中将在新一代溶液几何模型的基础上引入正态分布函数,并采用逐项积分的方式将二元系代表点邻近区间内所有点的性质和多元系点的性质联系在一起,以达到改进模型的目的。利用改进后的新一代溶液几何模型计算了In-Sn-Zn和Ag-Bi-Sn两个液态合金体系的相关物化性质,所得预测结果与文献中的实验数据吻合较好,表明了这一改进思路的合理性。
The normal distributed function and use the item-by-item integral method were introduced in this paper based on the new generation solution geometry model,which will relate the properties of all points in the neighborhood of the binary system representative points to the properties of the multi-component points.The physicochemical properties of the two ternary liquid alloys In-Sn-Zn and Ag-Bi-Sn were calculated by using the modified model,and a good accordance was obtained between the prediction results and reference values,which proves the rationality of the improvement idea.
