摘要
由Ｍｉｅｄｅｍａ二元合金生成热模型得到计算任意二元系中组元活度的新公式，该公式适用于任何液态和固态溶液，通过对大量的实验结果进行对比表明，用该方法计算的结果和实验值吻合较好．
A new formula for calculating the activities of the components in any binary system has been proposed based on Miedema's model for calculating the formation heat of binary alloys.The formula can be used in both solid and liquid solutions. This method has been used to calculate the activities in the binary system taken from 75 elements. The results show that this method is feasible and agrees very well with the experimental data for most systems. The ratio of the same sign of either the positive deviation or the negative deviation to solution reaches 87.5 %.
