摘　　要：利用ＡＲ２５２２活动区多波段的观测资料，分析了暗条演化与１Ｂ／Ｍ４级双带耀斑爆发之间的关系．结果表明：（１）足点的剪切运动导致暗条电流增强和耀斑贮能；（２）暗条上升运动和绞扭现象是暗条电流增强和耀斑贮能的结果；（３）Ｍａｒｔｔｅｎｓ—Ｋｕｉｎ模型至少适合于解释与暗条快速上升有关的双带耀斑爆发．With observational data in several bands in region AR2522, the relationshipbetween the evolution of the filament and the eruption of 1B/M4 two-ribbon flareis analysed. It is shown that: (1) the shearing movement of the filament footpointleads to the increase of the current intensity and the stored energy for the flareeruption; (2) the ascending motion and twisting of the filament are the results ofthe increasing current intensity and the stored energy of the flare, (3 ) Martens Kuin model is applicable to illustrate eruptive phenomena of the two-ribbon flarerelated to the filament with rapid motion.
