【Abstract】 The two solar radio spectrometers on the bands of 1.0-2.0GHz and 2.6- 3.8 GHz respectively have put into operation at National Astronomical Observatory of China (NAOC) from January 1994 and September 1996. There have been 297 and 316 solar radio events recorded up to April 10, 2000 by these two spectrome- ters. High sensitivity as well as high frequency and time resolution is characterized by these records. They provide a rich and valuable information for studying the evolution process of solar flare with the various time periods. A typical solar radio event of them on April l5, 1998 shows a variety of the morphological features and fine structures on this frequency range.更多还原
