在磁赤道面附近，径向距离约为2 ~ 5 RE处，经常观测到强电磁噪声带。最近使用Imp 6和豪克耶1卫星进行的宽带波形测量表明，赤道噪音由许多谐波间隔线的复杂叠加组成。在同一频谱中，几个明显不同的频率间隔往往是明显的。频率间隔通常在几赫兹到几十赫兹的范围内。本文的目的是提出这些波与高能质子，α粒子和其他重离子相互作用被困在磁赤道附近。这些波在控制高能离子的分布中可能发挥的作用被认为是。
An intense band of electromagnetic noise is frequently observed near the magnetic equatorial plane at radial distance from about 2 to 5 RE. Recent wide band wave form measurements with the Imp 6 and Hawkeye 1 satellites have shown that the equatorial noise consists of a complex superposition of many harmonically spaced lines. Several distinctly different frequency spacings are often evident in the same spectrum. The frequency spacing typically ranges from a few hertz to a few tens of hertz. The purpose of this paper is to suggest that these waves are interacting with energetic protons, alpha particles, and other heavy ions trapped near the magnetic equator. The possible role that these waves play in controlling the distribution of the energetic ions is considered.
