摘 要: 根據(jù)熔鹽和氧化物固溶體中正負(fù)離子未分開和熔锍電導(dǎo)大于熔鹽和氧化物固溶體的事實，按照正負(fù)離子未分開的原則制定了含共晶體和含復(fù)雜化合物二元熔锍的作用濃度計算模型，計算結(jié)果符合實際，從而證明所制定的模型可以反映相應(yīng)二元熔锍的結(jié)構(gòu)本質(zhì)。

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
