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 S_p 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.
