| 摘 要： | 本文采用一个表征高能耀斑强度的综合指数,分析了太阳活动21周以来(1976.7—1991.2)级别≥M1.0的X射线耀斑和能量≥10Mev的质子耀斑综合指数的时空分布,提出在研究时段内太阳上的13个高能耀斑“热点”。这些热点活动区反复回转,爆发了占总指数58.1％的高能耀斑。本文还讨论了高能耀斑热点的特征及其与大尺度磁场演化的关系。结果表明,高能耀斑热点与大尺度磁场的演化关系密切,前者受后者的调制。

| Abstract: | A comprehensive high-energy flare index is used to be characteristic of the high-energy flare intensity. The time and spatial distributions of the comprehensive indices of the energetic flares which have been observed since Cycle 21 are analysed and 13 "hot spots" of such flares during this period are given in this present article. The active zones of the hot spots appeared repeatedly and there erupted the energetic flares accounting for 58.1 percent of the total indices. The characteristics of the hot spots and the relationship between them and the evolution of the large scale magnetic fields are also discussed, with the results showing that the evolution of these spots has close relation to that of the large scale magnetic fields and the former is modulated by the latter. |
