| 摘 要： | 等离子体作为物质的第四态，与一般物质有着不同的特性，尤其是电磁性能更为复杂。本文研究非相对论情况下等离子体的磁导率。推导出非相对论麦克斯韦粒子分布情况下的介电常数，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，数值计算了两种典型等离子体波色散关系下的磁导率。结果表明，在等离子体中那些不满足色散关系的波很快就衰减，满足色散关系的波，磁导率仅仅是频率的函数。同时，等离子体磁导率还受温度的影响。

| Abstract: | As the fourth state of material,plasma differs from other material.In this paper the plasma permeability in non-relativistic case is studied.According to the relation between plasma permeability and dielectric constant derived by Silin,the permeabilities in connect with dispersion relation are numerically calculated.The results show that,the wave among plasma which doesn't satisfy the dispersion relation will decay quickly and the permeability of those waves which satisfy the dispersion relation is the function of frequency.And the plasma permeabilities are influenced by its temperature. |
