| 摘 要： | 报道了由Ｙｏｈｋｏｈ软Ｘ射线望远镜（ＳＸＴ）和日本国立天文台（ＮＡＯＪ）的太阳耀斑望远镜（ＳＦＴ）于１９９２年６月４日共同记录到的一次耀斑前相的磁重连过程．理论预言的重连所必需的磁力线被携带进入电流片的入流运动，热等离子体从电流耗散区（重连区）被排出的出流运动，出流引起的蒸发流动和Ｈ 耀斑核，以及磁力线开放等现象均在观测中得到证实．在分析观测事实的基础上，提出磁力线重连的唯象模型．

| Abstract: | A direct observation a magnetic reconnection event that occurred in the flare ofAR 7186 Of 1992 June 4 and observed by both the Soft X-ray Telescope (SXT) aboard theYohkoh spacecraft and the Solar Flare Telescope (SFT, NAOJ, Mited), is reported in thisarticle.Phenomena predicted by the theory of reconnection, such as the necessary inflowof field lines into the current sheet, the outflow of thermal plasma expelled by the currentsheet, the evaporstion and H flare kernels caused by the outflow, and the opening-out ofmagnetic filed lines, have been confirmed the observations. Based on an analysis of theobservations, phenomenological model of magnetic field line reconnection is sketched. |
