在分米波段太阳射电Ⅲ型爆发的观测特征

THE CHARACTERISTICS OF THE OBSERVATION OF MICRWAVE TYPE Ⅲ BURSTS AT 1 2GHz

本文叙述了分米波段Ⅲ型爆发的观测结果（１９９７ ．１１９９８ ．４） 。对５０ 个事件分析后，获得了单峰，多峰。

In this paper,50 microwave type Ⅲ bursts recorded at 1 2GHz with Solar Radiospectrometer at Beijing obseratory are analysed.Four kinds of type Ⅲ bursts are obtained,including single peak,multi peaks,groups,and absorption.The characteristics of bandwidth,frequency drift,polarization are also discussed.
