摘要
北京天文台１ ．０２ ．０ＧＨｚ 太阳射电频谱仪从１９９４ 年开始观测至１９９８ 年９ 月记录到太阳射电爆发１７１ 个，２ ．６３ ．８ＧＨｚ 太阳射电频谱仪１９９６ 年９ 月投入观测至１９９８ 年９ 月，记录到１４６ 个太阳射电爆发。１９９８ 年４ 月１５ 日太阳射电爆发同时在这两台频谱仪上记录到。这个事件在时间和频率上显示了丰富的幅度和结构的变化。发现了微波Ⅲ型爆发对群，并存在着丰富的快速活动现象。取得了高时间分辨率、高质量的动态谱资料，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。
The solar radio spectrometers at Beijing Observatory at 1.0 2.0GHz from 1994 to september 1998 and at 2.6 3.8GHz from september 1996 to september 1998 at Beijing Observatory.171 and 146 bursts have been registered at 1.0 2.0GHz and 2.6 3.8GHz,respectively,with a wealth of fine structures in time and frequency.The solar radio burst was recorded at the same time by the two spectrometers on April 15,1998.Some new interesting results are found,suchas a pair of microwave type Ⅲ bursts and rich fast fine structures.The data of dynamic spectrogram of high temporal resolution and high quality were obtained.The solar radio bursts at different frequencies reflect the evolving processes of solar flares in time and space,and provide a basis for the researches on solar flares.
