| 摘 要： | 本文总结了北京天文台1991年的2840MHz波段微波爆发中精细结构（FS）事件的观测．从FS的时间标度、强度、共生的微波爆发的峰值流量、FS发生在微波爆发的相位和FS与Hα耀斑的关系等方面作了统计分析．发现约67％以上的FS其持续时间为几十毫秒到几百毫秒，85％以上的FS幅度小于200sfu．讨论了FS的时标、强度及22周太阳峰年期与21周FS出现率的差别．

| Abstract: | In this paper, a summary of the statistical results of microwav fine structure (FS)events recorded by BAO at 2840MHz in 1991 is presented. Statistical analyses are made for the time scale, flux density, the peak flux of associated microwave bursts, the relation between FS and H. flare and so on. They show that the time scales of more than 67% of FS events are between tens of millisecond and hundreds of miilisecond, and the amplitudes of FS events of more than 85% are less than 200sfu. A discussion on the time scale and intensity of FS, as well as on the difference of the occurrence rate of FS events in the 21st and 22nd solar activity cycle, has also been made. |
