AbstractSix metric type Ⅲ burstswith bidirectional frequency drifts observed with theAcousto-Optic Spectrograph at the Yunnan Observatory during the 22nd solar cycle are analysed in the present article. These events respectively reveal that the demarcation frequencies between the positive and negative drift bursts are in between 244 MHz and 272 MHz. The radiation mechanism of the type Ⅲ drift pair events is also discussed from the observation characteristics.
Other Abstract分析了云南天文台声光频谱仪在 2 2周峰年期间观测到的 6个具有双向频率漂移的米波Ⅲ型爆发对。这些事件分别揭示了在正向和反向漂移爆发之间的界面频率在 2 4 4~ 2 72MHz之间 ;频率漂移率在 3 2~ 1 98MHz/s之间 ;寿命为1 .1~ 3 .4s;带宽在 4 3~ 70MHz之间 ;与Hα耀斑相关为 1 0 0 % ,其中 3 3 %的爆发发生在Hα耀斑的初始时刻 ,这说明它们与磁重联初始能量释放有关 ;50 %的爆发与X射线对应。从观测特征出发 ,讨论了它们可能的辐射机制
