摘　　要：国家天文台 １．０－２．０ＧＨＺ，２．６－３．８ ＧＨｚ太阳射电频谱仪从１９９４年１月和１９９６年９月投入观测至２０００年４月１０日记录到太阳射电爆发分别为２９７个和３１６个．取得了高质量的高时间分辨率、高频率分辨率的动态谱资料，为研究耀斑各种尺度的时间及空间演化过程提供了丰富的信息．１９９８年４月１５日的共同事件在时间和频率上显示了丰富的幅度和结构的变化．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.
