摘要
利用自由体积理论和新一代几何模型，建立了三元金属熔体活度系数１ｎ的模型表达式，计算出１８７３Ｋ温度条件下铁基熔体中组元的活度系数，并将模型计算结果与文献精选数据进行比较，表明活度系数的模型计算结果与文献精选数据相当吻合。
The express of activity coefficient 1n for liquid ternary metal solution is derived from thefree volume theory and new generation solution model, the activity coefficients of component i in iron - basedsolution are calculated at 1873 K. The results are good in agreement with the selected experimental values.
