摘要
介绍了北京天文台已投入观测的１．０—２０ＧＨｚ，２．６—３．８ＧＨｚ太阳射电频谱仪及１９９９年投入观测的５．２—７６ＧＨｚ太阳射电频谱仪．它们是第２３周太阳活动峰年我国太阳物理界的重要观测设备已投入观测的频谱仪获得不同类型的太阳射电爆发资料分别为１７１个和１４６个，这些事件在时间和频率上有丰富的幅度和结构的变化．不同太阳射电爆发反映太阳大气不同高度上耀斑的时间和空间的演化过程，为研究不同大气高度中耀斑物理动力学过程、能量释放、粒子加速提供了更多的依据．
In the paper the solar radio specrtometer in 1.0--2.0GHz and 2.6-3.8GHzwhich are working and the 5.2-7.6 GHz spectrometer which will come into operation in 1999, are introduced. They are the key observation facilities of solar physicscommunity in China for the coming 23rd solar active maximum years. 171 and146 bursts of different types in l.0 2.0 GHz and 2.6--3.8 GHz, respectively, with awealth of fine structure in time and frequency has been registered. The solar radiobursts at different frequencies reflect the evolving processes of solar flares in timeand heigh, and provide useful data for the study of solar flares.
