| 摘 要： | 北京天文台在２．８４ＧＨｚ频率上观测到的带短时标精细结构的微波爆发与日本ＹＯＨＫＯＨ卫星上ＨＸＴ在１９９１年１０月－１９９２年１２月观测到的硬Ｘ射线爆发（ＨＸＢ）事件作了比较，发现在２０个微波精细结构爆发事件只有１２个与ＹＯＨＫＯＨ卫星记录的ＨＸＢ有对应关系．本文对１９９２年６月７日典型事件中２．８４ＧＨｚ与ＨＸＢ共同存在的百秒量级的准周期振荡作了分析及源区参数的计算，并作了简要的讨论．

| Abstract: | Much attention is given to the correlation between solar microwave bursts and hard X-ray flares'The solar microwave bursts with fine structures(FS) at 2.84GHz observed at BAc are compared with hard x-ray flares(HXB)recorded with YOHKOH satellite from Oct. 1991 to Dec.1992.It is found that during this time interval only 12 out of 20 microwave FS events are related with HXB of YOHKOH observation.The June 7,1991 events is analysed.The quasi-period pulsations with an average period of about one hundred seconds which explained with MHD oscillation is found in the descending phase of the event at both 10cm and HXB. Some parameters.of source region are also deduced. |
