摘 要: 根据熔盐和氧化物固溶体中正负离子未分开和熔锍电导大于熔盐和氧化物固溶体的事实，按照正负离子未分开的原则制定了含共晶体和含复杂化合物二元熔锍的作用浓度计算模型，计算结果符合实际，从而证明所制定的模型可以反映相应二元熔锍的结构本质。

Abstract:Based on the facts that cations and anions of molten salts and binary oxide solutions don't separate from each other as well as that the electric conductivities of mattes are greater than that of salts and oxide solid solutions, calculating models of mass action concentration for binary mattes involving eutectic or complex compound have been formulated according to the same principle that cations and anions of matte also don't separate from each other. Calculated results agreed well with measured values, this in turn shows that the calculating models can reflect the structural characteristics of binary mattes concerned.
Key words: matte activity eutectic complex compound mass action concentration
