In the present paper, the relation between the CMEs and their linked solar flares is examined during the entire solar cycle 23. During this solar cycle and under certain temporal and spatial conditions, 521 CMEs linked with solar flares are selected. These selected CMEs are separated into two groups according to their time of detection, 254 Before Flare-ECME events (BF-CMEs) and 267 After Flare–ECME events (AF-CMEs). The results showed that the spatial separation angle between the CMEs and their linked flares has a peak between ± 25°. Also, it was found that there is a trend of decreasing the CME acceleration with the increasing of CME speed. Besides we obtained that the AF-CMEs are on average more massive and energetic than BF-CMEs. Finally, we found that the CME Mass-Width relation of AF-CMEs is more correlated to their associated flare events than BF-CMEs.

日冕物质抛射与太阳耀斑联系事件的性质

在本文中,在整个太阳周期23中检查了CME及其链接的太阳耀斑之间的关系。在此太阳周期中,在某些时空条件下,选择了521个与太阳耀斑链接的CME。这些选定的CME根据其检测时间分为两组,分别是254个Flare-ECME事件之前(BF-CME)和267个Flare-ECME事件之后(AF-CME)。结果表明,CME及其连接的火炬之间的空间分离角在±25°之间有一个峰值。另外,发现随着CME速度的增加,存在CME加速度降低的趋势。此外,我们得出的结论是,与BF-CME相比,AF-CME平均更重,更有活力。最后,
