为了更好地理解离子熔体的电导率机制，添加剂二元系统比纯熔体产生更多启发性信息。因此，讨论了单价阳离子与共同阴离子的迁移等温线。解释了外部和内部流动性的差异。简要提及了确定混合物中单个离子种类的传输数的方法。常见阴离子二元体系中单价阳离子内部迁移率等温线的分布可分为两类。在大多数二元熔体中，都会发生等温线的交叉。基于分子动力学模拟和实验数据给出了离子迁移率逆转的解释，为阐明熔盐中离子输运机制提供了线索。
For a better understanding of the mechanism of electrical conductivity of ionic melts, additive binary systems yield more heuristic information than pure melts do. Thus, mobility isotherms of monovalent cations with a common anion are discussed. The difference in external and internal mobilities is explained. The methods for determining transport numbers of individual ionic species in mixtures are briefly mentioned. The profiles of the isotherms of the internal mobilities of monovalent cations in common anion binary systems may be classified into two types. In most of the binary melts a crossing of the isotherms occurs. Interpretation of the ionic mobilities reversal is given based on molecular dynamics simulation as well as experimental data, which is a clue for elucidation of the mechanism of ionic transport in molten salts.
