中文摘要：

对国家天文台5．2～7．6GHz频谱仪在23周太阳活动峰年期间（1999．8～2003．10）记录到的Ⅲ型爆发，与日冕物质抛射（CME）、Ha耀斑及相关事件作了统计分析。发现微波Ⅲ型爆发与CME的关系没有Ⅱ型射电爆发与CME的关系密切；与CME对应的Ha耀斑91％的都是渐变耀斑，且90％的渐变耀斑发生在CME之前，平均在前29分钟，仅有10％的耀斑发生在CME之后，平均在后4分钟；从这些统计特征出发，讨论了它们的辐射机制。

英文摘要：

The Statistics analyses of the microwave type Ⅲ bursts, coronal mass ejections （CMEs）, Ha flares and relevant events observed with 5200 - 7600 MHz spectrograph at the National Astronomical Observatory during the 23^rd solar cycle are carried out in this article. It is found that the relation between the microwave type Ⅲ bursts and CMEs is not closer than that between the type Ⅱ radio bursts and CMEs; the Ha flares corresponding to the CMEs are all gradual flares.
