通过对正规溶液模型的修正，并引入ＣＡＬＰＨＡＤ技术，构成了物理意义明确和数学形式简洁的冶金熔渣亚正规（ＳＲｅＳ）模型，这实际上是ＳＥＬＦ－ＳＲｅＭ模型的一种发展．应用ＳＲｅＳ模型对若干硅酸盐、两性化合物以及简单离子二元熔体的热力学性质进行了计算，所得结果比正规溶液模型能更好地符合实验事实 Through the modification of the normal solution model and the introduction of the CALPHAD technique, the MetSurgical Metallurgical Slag Subnormal (SReS) model, which has a clear physical meaning and a simple mathematical form, is actually developed as a SELF-SReM model. The thermodynamic properties of some silicates, amphoteric compounds and simple ionic binary melts were calculated using the SReS model. The results obtained were better than those of the normal solution model in experimental facts
