| 摘 要： | 本文利用电流不稳定性线性理论讨论了１９９２年６月２５日至２６日耀斑后环中出现不均匀“结”状结构（“ｋｎｏｔ”或“ｂｌｏｂ”）的可能性，并且在同时考虑重力、磁力和环顶物质下落初速的情况下，理论计算了１９９２年６月２６日Ｈα耀斑后环物质运动的规律。理论计算与观测求得的视向速度随高度分布的曲线基本符合。

| Abstract: | Using the theory of linear current instability, we discussed the possibility of inhomogeneous "knot" strUctures within the post-flare loop of June 25-26, 1992. Besides,by simulboeously considering gravity of the sun, magnetic stress within the loop and primary velocity at the top, we theoretically calculated the inchon of matter within the post-flare loop. The theoretical results are in accord with observations. |
