摘要
叙述了１９９７年１月至１９９８年４月，使用北京天文台７ｍ射电望远镜在１－２ＧＨｚ频率上观测的微波Ⅲ型爆发的分析结果．共分析６０个事件，获得了单峰、多峰、群集和负吸收微波Ⅲ型爆发的四种型别．通过对它们的频宽、频漂、偏振等重要参量的分析，初步得出微波Ⅲ型爆发在１－２ＧＨｚ上的一些基本特性．
0 microwave type Ⅲ bursts recorded at 1-2 GHz with the solar-radiospectrometer ofBeijing Observatory were analysed. Four kinds of type Ⅲ bursts were recognized, characterized by single peaks, multi-peaks, groups, and absorption features. After analysing theirbandwidths, frequency drifts, and polarizations we obtained preliminarily some of their basicfeatures.
