基于熔盐中阳离子和阴离子的朗之万方程，结合离子质量讨论了离子部分电导率。这些部分电导率以电流-电流相关函数的形式表示，作为 Kubo 理论的扩展。并且这些部分电导率也用电导率张量来描述，电导率张量是从宏观不可逆热力学角度引入的。这些理论结果通过对熔融 NaCl 和 NaI 进行的分子动力学模拟得到了证实。
Based on the Langevin equations for cations and anions in a molten salt, the ionic partial conductivities are discussed in connection with their masses. These partial conductivities are shown in terms of current-current correlation functions as an extension of Kubo theory. And these partial conductivities are also described in terms of conductivity tensors which are introduced from the macroscopic irreversible thermodynamic viewpoint. These theoretical results are justified by the molecular dynamics simulations carried out for molten NaCl and NaI.
