THE OUTSTANDING OF THE SOLAR RADIO BURSTS AND TypE II RADIO BURSTS

摘要: 本文分析了北京天文台2840MHz射电望远镜,1989年1月-1993年12月期间观测到的太阳射电爆发的显着事件与米波Ⅱ型、Ⅳ型爆发的对应关系,从相关结果来看,爆发的峰值流量越高△T越短,这说明当太阳流量越大,高达500s.f.u.以上时,Ⅱ型爆发会在爆发的峰值前后很短时间内发生,可能与粒子的加速有关。Abstract: This discussion is based on the outstanding events of solar radio bursts observed by Beijing Astronomical Observatory and Type II, IV radio bursts during 60 months, from Jan.11989 to Dec.30,1993.The Data of radio bursts of Type IIand IVare from S. G. D.,The results of the correlation between Sp and △T and solar flux show that the higher the flux is,the shorter the △T. When solar flux is very high or even more than 500 s.f.u.,Type IIonset procedes microwave burst maximum or occurs later.These results show that they may connect with high particles'acceleration.
