| 摘 要： | 基于KF模型和Gaye模型,得到改进的KF模型,并推导出三元体系的表达式。把该模型应用到三元SiO2-CaO-MnO熔渣体系,通过对二元系研究得到模型参数,从而可计算三元系中组元的活度。结果表明计算结果与实验结果的相对偏差分别为：SM＊nO1 823K=19.3%,SM＊nO1 773K=28.1%。表明该理论在SiO2-CaO-MnO熔渣体系的应用是可行的。

| Abstract: | The improved KF model is based on KF model and Gay model,and the component activity expression of ternary system is also deduced.The improved KF model is applied into the ternary SiO2-CaO-MnO molten slag system,and through the study on binary system,the model parameters can be obtained,so the component activity of ternary system can be calculated.The result shows the relative deviation between calculation result and experimental result of MnO at 1 823 K and 1 773 K are: S*MnO 1 823 K=19.3%,S8MnO 1 773 K=28.... |
