本文利用光球磁场、色球Hα单色像和Hβ速度场等观测资料，分析了1993年5月日面AR7500中3个暗条的演化和动力学行为，得出4个结论：(1)3个暗条中两个是右旋暗条，一个是左旋暗条。(2)暗条附近两侧的色球纤维和光球横场几乎平行于暗条长轴，暗条端点处的黑子没有呈现明显的涡旋结构。(3)尖角处因为轴向场取向不同，一直没有发生暗条合并，即使其中一个右旋暗条消失后又重新形成也如此。(4)几天持续存在的左旋暗条，在两天的观测中未出现扰动激活，其中部为杂乱而不明显的运动图案。本文还讨论了可以用暗条的扭曲磁流绳模型来解释暗条的这些动力学行为，以及一些尚待进一步澄清的问题。

An analysis of the evolution and dynamical feature of three filaments using the magnetogram of photosphere and Hβ Dopplergrams of chromosphere in AR7500 on May,1993 is presented in this paper.Conclusions are as follows:1)There are two dextral and a sinistral in three filaments.They constitude two cusps.One of the cusp is rooted in positive polarity plage region,which has blueshift motion and velocity cusp.While the other in a small decaying spot with negitive polority has redshift motion.The both ends in other side extend into the big negative polarity sunspot and positive polarity plage region respectively.The red and blue-shift motions of these cusps and both ends exist 24 hours continually.2)Both chromospheric plage associated fibrils near the filament and the transverse magnetic field of the photosphere beneath the filaments almost parallel to the long axis of these filaments.The sunspot of the end does not present obvious spiral structure.The orientations of the field along with the axis are different in these three filaments,and the possible direction of the flow of the electric current is identical.There are matter motion along the direction of the axis of magnetic field in two filaments,but this has no relationship with the difference of the handedness;it has symmetrical fall motion in the axis direction at the other dextral filaments of trouble activation.3)The axis field has different direction in cusp so that it does not always occur with merge of filament,as a dextral filament disappears and forms again.When two sinistral and dextral filaments disintegrate into parallel fibrils which connect the same positive or negative polarity,their cusps clearly exist due to the different handedness.4).The sinistral filament exists during several days,but no trouble activation in the two observing days.A dextral filament has trouble activation and “relaxing” turning round before disappearance.The other dextral filament exists for a long term presenting obvious trouble activation within the two days.
