| 摘 要： | 磁重联被认为是太阳耀斑的产生机制，本文数值模拟在日冕中发生在磁重联过程，结果表明耀斑环的表观运动是磁重联的自洽结果；由重联点发出的慢激波对耀斑环的加热有贡献；耀斑环的上升并不意味着重联点的上升。

| Abstract: | Magnetic reconnection was proposed to account for the solar flares. This paper numerically simulates the magnetic reconnection occurring in the corona. It is shown that the apparent motions(the rise of the flare loop and the separation of its footpoints) are the natural results of the magnetic reconnection. Slow MHD shocks emanating from the X point contribute to the flare loop heating. It is interesting to point out the flare loop may rise despite of the spatially fixed reconnection point. |
