中文摘要:

太阳的日冕是太阳的空气的最外面的部分。在阳光和地球,空间天气和地球本身之间的花冠活动影响空间环境。全部的太阳的日蚀(TSE ) 是最好的机会在地面上观察太阳的日冕。在 TSE 2008 期间,日冕的一系列图象和太阳的磁盘的部分日蚀用望远镜和电荷耦合器件照相机被获得。在图象处理以后,花冠结构的初步的结果被给,并且光线的亮度在杆的方向和阳光的赤道日冕介绍被测量。尽管在太阳的活动日冕的最小,形状和结构不是对称。赤道的区域比极的是更多的程度,并且也东方和西方之间有更大的差别赤道的区域并且在向南并且向北极的区域之间。赤道的东方方面上的花冠溪流 ers,特别地在东方南方方向的最大的,是很明显的。在向南极的区域的花冠羽毛在向北极的区域比那由更多的极的光线组成。这些结构也在 SOHO 的另外的观察和数据被显示出。在杆和赤道的方向的光线的亮度侧面类似于在太阳的最小的凡·德·胡尔斯特模型的那些,但是由于花冠活动有一些差别,它在日冕的 isophote 地图被显示出。

英文摘要:

Solar corona is the outermost part of the solar atmosphere. Coronal activities influence space environment between the Sun and the Earth, space weather and the Earth itself. The total solar eclipse (TSE) is the best opportunity to observe the solar corona on ground. During the TSE 2008, a series of images of the corona and partial eclipse of solar disk were obtained using telescope and CCD camera. After image processing, preliminary results of coronal structure are given, and radial brightness profiles of the corona in directions of pole and equator of the Sun are measured. Though in solar activity minimum, the shape and structure of the corona are not symmetry. The equatorial regions are more extent than the polar one, and there are also larger differences between the east and west equatorial regions and between the south and north polar regions. Coronal streamers on east side of the equator, particularly the largest one in east-south direction, are very obvious. The coronal plume in south polar region consists of more polar rays than that in north polar region. These structures are also shown in other observations and data of SOHO. The radial brightness profiles in directions of pole and equator are similar to those of the Van de Hulst model in solar minimum, but there are a few differences due to coronal activity, which is shown in the isophote map of the corona.
