论文摘要
该论文专门纪念Alfvén浪潮的周年纪念日。 Alfvén波的概念在宇宙电动力学的形成和发展中发挥了出色的作用。 Alfvén波的一个独特特征是，在空间中的每个点上，组速度向量和外部磁场矢量彼此共线。结果，Alfvén波可以在长距离内携带动量，能量和信息。我们简要描述了两个Alfvén谐振器，其中一个是在电离层中形成的，第二个可能存在于地球辐射带中。理论上证明了电离层谐振器的存在是合理的，并通过许多观察结果证实。第二个谐振器位于地面上方相对于地磁赤道的平面对称地位于地球上方的反射点之间。关键词：alfvén速度，分散法，群速度，几何光学元件，重离子。
The paper is dedicated to the anniversary of the discovery of Alfvén waves. The concept of Alfvén waves has played an outstanding role in the formation and development of cosmical electrodynamics. A distinctive feature of Alfvén waves is that at each point in space the group velocity vector and the external magnetic field vector are collinear to each other. As a result, Alfvén waves can carry momentum, energy, and information over long distances. We briefly describe two Alfvén resonators, one of which is formed in the ionosphere, and the second presumably exists in the Earth's radiation belt. The existence of an ionospheric resonator is justified theoretically and confirmed by numerous observations. The second resonator is located between reflection points located high above the Earth symmetrically with respect to the plane of the geomagnetic equator. Keywords: Alfvén velocity, dispersion law, group velocity, geometric optics, heavy ions.
