Interrelations between the problems of electrical conductivity of a completely ionized plasma and the ion drag force in a dusty plasma are discussed. It is shown that a physically motivated modification of the Coulomb logarithm proposed in the context of ion-particle scattering in dusty plasma allows us to improve the theoretical description of the conductivity in the moderately non-ideal regime. A simple theoretical expression obtained is in reasonable agreement with available results from experiments and numerical simulations.

关于非理想中度完全电离等离子体的电导率

讨论了完全电离的等离子体的电导率问题与尘土等离子体中的离子阻力之间的相互关系。结果表明，在尘土等离子体中离子粒子散射的背景下，对库仑对数进行了物理上的修改，使我们能够改进中度非理想状态下电导率的理论描述。获得的简单理论表达式与实验和数值模拟的可用结果在合理范围内一致。
