| 摘 要： | 本文用数据方法分析了紫金山天文台色球望远镜观测的１９９６年３月２４日３Ｂ级双带主资料，结果表明：由于新浮磁流改变背景磁场，光球剪切运动引起暗条圆柱轴向磁力线扭转而使暗条电流增加，致使暗条整体力学平衡破坏，驱动暗条向上运动。并对暗条上升运动与耀斑爆发的物理关系进行了分析讨论。

| Abstract: | this paper, The data of a large two-ribbon flare observed by Purple MountainObservatory on March 24, 1966 are analysed numerically. The results show that: Thefilament activation plays an important role in the triggering of the flare and bothemerging heteropolarity flux in the active region and photospheric shearing motionnear the filament footpoint are responsible for the filament eruption. The emergingflux causes the change of the background field and the photospheric shearing motionwhich twists the edal magnetic field inside the filament leads to the increase of thecurrent intensity, so that the equilibrium of the filament is untable and the filamentmotion upwards occurs' Finally the physical relation between the ascension motion ofthe filament and the eruption of the flare is analysed and discussed. |
