摘　　要：通过对0.5[xNa_2O—(1-x)Li_2O]—0.5P_2O_5和0.3[xNa_2O—(1-x)Li_2O]—0.7B_2O_3两个非晶态碱金属离子玻璃体系的制备和测试,证明了非晶态快离子导体中“混合碱效应”的存在,并由实验曲线找出了这两种玻璃材料的转变温度T_8、离子电导率σ_T、幂前因子σ_O和激活能E_a分别与组成该材料的摩尔分数x之间的相互关系。Two classes of amorphous alkali ionic glass systems were prepared and measured. These systems are: 0.5[xNa_2O—(1-x)Li_2O]—0.5P_2O_5 and 0.3[xNa_2O—(1-x)Li_2O]—0.7B_2O_3. It is found that the 'mixed alkali effect'exists in these amorphous rapid ionic conductors. From the experimental curves, we obtained the relation between the mole fractions of material compositions xand the glass transition temperature Tg, ionic conductivity σ_T, activation energy E_α, and forepower factor σ_o of these materials.
