Abstract太阳对于人类生活的重要性是不言而喻的。对于人类的认知来说,太阳同样是我们必须面对的问题。虽然它是距离我们最近的恒星,但是我们对它的了解还是远远不够。现在随着地面和空间观测的不断进步,使我们掌握了更加有利的研究工具。 本文利用多波段观测资料对暗条爆发及相关事件进行研究,我们得到了一些结论,这有助于最终揭开太阳的本质问题。 本文分为以下几个部分: 第一章调研了和研究相关的暗条爆发和耀斑方面的有关文献,并讨论了二者之间的联系,以及和暗条以及耀斑相关的太阳活动现象。 第二章利用Hα、EUV和软X射线等多波段观测资料,对发生在太阳宁静区中的小暗条爆发进行了详细描述和研究。我们认为小暗条爆发和大尺度暗条爆是十分相似的。对小尺度事件的研究可以帮助我们了解大尺度事件的本质。 第三章我们使用了Hα、He I 10830 Å、EUV和软X射线(SXR)资料,研究了一个位于日冕中心附近宁静区中的暗条爆事件,该事件发生在2006年1月12日。这次暗条爆发伴随有一个双带耀斑,两个瞬现冕洞和一个partial halo CME。同样是小尺度事件可以帮助我们了解各种爆发事件之间的演化和联系。 第四章对全文进行了总结和展望
Other AbstractThe Sun maybe is the most important thing in human life, which is we cann’t say more about. The sun is a very vital problem in our way to the unknown world. We have to face this challenge. Although it is the nearest star to earth, we know only a little about it. As the ground and space observations are make progress everyday, we get more and more high cadence data. We believe finally the whole questions of sun can be answer. In this paper, We study in some filament eruptions and flares by using multi-wavelength observations, and get a few results which is helpful to understand the nature of the sun. It ‘s structured as follow: In chapter one, on the base of surveying a number of references, we summarized the basic knowledge to filaments and flares, and discuss the relationship between them. In chapter two, We analyzed multi-wavelength observations such as Hα, EUV and soft X-ray, to study the eruption of a small filament. we find several similar characters between small filaments and large-scale filaments. It is clear that observations of small-scale filament eruptions could help in clarifying the questions of large-scale one. In chapter three, By using Hα, He I 10830, EUV and soft X-ray (SXR) data, we examined a filament eruption occurring on 2006 January 12. The event was associated with a tow ribbons flare, two transient coronal holes (TCHs) and a partial halo coronal mass ejection (CME). This small events which cause a partial halo CME can be a great help to understand the relationship between those whole solar activities. Finally, we describe the conclusion from the above studies and the future of our work.
