摘要
对第23太阳周的太阳高能粒子、米波段和DH波段Ⅱ型射电暴的爆发时间和高度进行了统计分析。结果表明:耀斑和日冕物质抛射(coronal mass ejection,CME)产生后,先后爆发米波、DH波Ⅱ型射电暴和高能粒子事件,它们爆发的高度也由低到高。米波、DH波Ⅱ型射电暴的爆发时间和高度同太阳高能粒子事件是否发生并无明显关系,但伴随米波段和DH波段Ⅱ型射电暴的CME有更高的产生太阳高能粒子事件的概率。
This paper statistically analyzes the onset time and height of metric,decameter-hectometric (DH) type Ⅱ radio bursts,and solar energetic particle (SEP) events during Solar cycle 23.Results show that the three events occur in sequence after occurrence of solar flares and coronal mass ejections (CMEs),with their onset heights in ascending order.Onset time and height of the type Ⅱ radio bursts has nothing to do with whether SEP happens.However,there is a greater statistical probability of SEP events for CMEs accompanied by metric and DH type Ⅱ radio bursts.
