本文综述了起源于冕洞的高速太阳风流前沿形成的太阳风中共转相互作用区(CIR)对高能粒子的三个重要影响。简要概述了CIR及其重要特征，接着讨论了星系宇宙线强度中与CIR相关的调制，重点是由航天器粒子望远镜“反符合”卫士所进行的观测。与中子监测器相比，这种防护罩结合了高的计数率(几百次计数/S)和较低的刚性响应，以提供宇宙线调制和CIR结构之间的关系的详细信息。然后描述了CIRS对木星电子的调制。最后，讨论了离子在∼附近对20 MeV/n能量的加速作用。
This paper reviews three important effects on energetic particles of corotating interaction regions (CIRs) in the solar wind that are formed at the leading edges of high-speed solar wind streams originating in coronal holes. A brief overview of CIRs and their important features is followed by a discussion of CIR-associated modulations in the galactic cosmic ray intensity, with an emphasis on observations made by spacecraft particle telescope ‘anti-coincidence’ guards. Such guards combine high counting rates (hundreds of counts/s) and a lower rigidity response than neutron monitors to provide detailed information on the relationship between cosmic ray modulations and CIR structure. The modulation of Jovian electrons by CIRs is then described. Finally, the acceleration of ions to energies of ∼20 MeV/n in the vicinity of CIRs is reviewed.
