太阳耀斑磁重联的数值模拟

数值模拟了太阳耀斑中二维磁重联过程。结果表明，当重联Ｘ 点比较高时，演化过程能再现双带耀斑中耀斑环的运动等主要特征；当重联Ｘ 点比较低时，可解释致密耀斑的观测特征。结果还表明，耀斑环上升和重联点上升之间没有直接的联系。

NUMERICAL SIMULATION OF THE MAGNETIC RECONNECTION IN SOLAR FLARES

D magnetic reconnection in solar flares is numerically simulated. The results show that when the reconnection occurs at a high altitude, the evolution can reproduce the main characteristics (such as flaring loop motions and footpoints separation, etc.) of two ribbon flares; while that with a low reconnection X point shows a large similarity to compact flares. Our results also indicate that there is no direct relation between the rises of soft X ray loops and the X point.
