利用观测到的磁流体动力波的物理性质来估计磁层中质量密度的技术被称为磁地震学。考虑到用粒子实验确定密度的困难，这种技术在磁层研究中是重要的。本文综述了基于驻波观测的磁震研究进展。这些研究的数据来源包括AMPTE/CCE、CRRES、GOES、Geotail、THEMIS、Van Allen Probes和Arase。我们描述了数据分析和密度建模技术，主要结果，以及在磁地震研究中仍存在的问题。
The technique to estimate the mass density in the magnetosphere using the physical properties of observed magnetohydrodynamic waves is known as magnetoseismology. This technique is important in magnetospheric research given the difficulty of determining the density using particle experiments. This paper presents a review of magnetoseismic studies based on satellite observations of standing Alfvén waves. The data sources for the studies include AMPTE/CCE, CRRES, GOES, Geotail, THEMIS, Van Allen Probes, and Arase. We describe data analysis and density modeling techniques, major results, and remaining issues in magnetoseismic research.
