[1]1994年12月11日，Geotail航天器在地球磁尾的X线周围遇到了一个活跃的重连扩散区。观察到三个有趣的特点。一种是磁岛通过和中性片穿过时面外磁场分量的四极斑图。第二种是在重联磁拓扑的分界线附近电子束的方向反转。第三个是明显的血浆流动逆转。通过结合等离子体、磁场、粒子和波的观测，本报告可能在微观水平上提供磁尾中多条X线无碰撞重联的证据。
[1] On 11 December 1994 the Geotail spacecraft encountered an active reconnection diffusion region around the X line in the Earth's magnetotail. Three interesting features were observed. One is quadrupole pattern of the out-of-plane By magnetic field component during the passage of magnetic islands and the crossing of the neutral sheet. The second is a direction reversal of the electron beams in the vicinity of the separatrix of the magnetic topology of reconnection. The third is a clear plasma flow reversal. By combining the observations of plasma, magnetic field, particles, and waves, this report may provide evidence of multiple X lines collisionless reconnection in the magnetotail at the microscopic level.
