中文摘要：

通过质量三角形模型计算了SrTiO3-La0．3Sr0．7TiO3-（La0．3Sr0．7）0．93TiO3三元体系中固溶体在100～900℃温度范围内的电导率，得到了等电导率图．对典型组分进行了实验验证，实验值和理论计算符合较好，说明质量三角形模型可以用于混合导体材料电导率的预报．

英文摘要：

The constant electric conductivity curves of solid solutions in the SrTiO3-La0.3Sr0.7TiO3-（La0.3Sr0.7）0.93TiO3 ternary system were obtained by estimating the electric conductivity of the solid solutions by a mass triangle model. Some typical compositions of the solid solutions were selected to verify the calculated results. The experimental values are consistent well with the predicted ones, demonstrating the feasibility of a mass triangle model in predicting the electric conductivity of mixed conductor.
