摘要
１９８２年１１月２３日开始的极高速太阳风流追赶强磁场结构的事件，形成了高密度前鞘－强磁场本体－高密度后鞘－高速流的组合结构．本文分析了此组合结构的磁流体动力学特征，发现在强磁场本体内出现行星际亚阿尔文波速流，并推论了其可能的成因．
On November 23, 1982, an extremely high-speed stream was overtaking a strong magnetic field structure, resulting in an interplanetary combinative structire including high-density front sheath, main part with strong magnetic field and low density, high density rear sheath, and extremely high-speed streams. The MHD characteristics of the combinative structure are analyzed in this paper. A sub-Alfvenic flow is found inside the main part of the strong magnetic field structure, the formation of which is also discussed.
