【摘要】 本文运用Ｍｉｅｄｅｍａ理论，系统地计算了镁与碱金属组成的二元合金系统的液态混和焓和固态合金形成焓．根据理想溶液理论，还计算了Ｌｉ－Ｍｇ系统在１０００Ｋ时的熵、以及自由能－成分曲线，所得的结果同已有的实验结果和第一原理赝势方法计算的结果符合得比较好更多还原

【Abstract】 The enhtalpy of solution of liquid phase and enthalpy of formation of solid state for the binary alloy systems of magnesium with the alkaline metals have beencalculated using the Miedema theory. The entropy and free energy versus compositionfor Li-Mg alloy at 1000°K have been also calculated with the ideal solution model.Thepresent results are in good agreement with the experimental data available and those cal-culated by the first principle.更多还原
