摘　　要：等离子体作为物质的第4态,与一般物质有着不同的特性,尤其是电磁性能更为复杂。本文研究非相对论麦氏分布等离子体介质的磁导率。在导出非相对论麦克斯韦粒子分布情况下的介电常数后,根据Silin提出的各向同性等离子体中磁导率与介电常数的关系,数值计算频率-波数空间的磁导率。结果表明,等离子体磁导率在频率-波数空间的分布与粒子密度及其温度有关。As the fourth state of material, plasma differs from other material. In this paper the plasma permeability in non - relativistic case is studied. Firstly, dielectric constant is derived in non - relativistic maxwell-distribution case, according to the relation between plasma permeability and dielectric constant derived by Silin, the permeabilities in frequency - wave number space are numericaly calculated. The results show that the plasma permeabilities are influenced by density and temperature.
