【摘要】 根据液液部分互溶二元合金系相图偏晶点和会溶点的温度与组成数据，应用遗传算法求解ＮＲＴＬ方程中的能量参数（ｇ２１－ｇ１１）、（ｇ１２－ｇ２２）和有规参数α１２之值，进而计算该类体系组分的活度系数，并以ＺｎＰｂ液液部分互溶二元系为例进行了活度系数计算，其结果与实测数据符合较好。更多还原

【Abstract】 The values of energy parameters, ( g 12 - g 22 ) and ( g 21 - g 11 ), and non random parameter, α , were calculated by solving NRTL equation with the aid of genetic algorithm and the values of the consolute and monotectic points of immiscible binary alloy phase diagram. By using these parameters, the activity coefficients of immiscible Zn Pb system at 923 K, as an example, were calculated. The results are in good agreement with the experimental ones.更多还原
