摘要

霍尔磁流体力学（HMHD）中的线性波与标准 MHD 波有着本质区别，这一点通过简洁的推导得到了证明。除了改变传统的 MHD 频谱之外，霍尔电流还诱发了一个由纯圆极化波组成的独特新分支，它可能成为具有代表性的剪切波。

Hall MHD waves: A fundamental departure from their MHD counterparts

It is demonstrated through a succinct derivation as to how the linear waves in Hall magnetohydrodynamics (HMHD) constitute a fundamental departure from the standard MHD waves. Apart from modifying the conventional MHD spectrum, the Hall current induces a distinct and new branch consisting of purely circularly polarized waves that may become the representative shear waves.
