| 英文摘要 | We investigate the magnetic structure of a small earthward-moving flux rope observed by cluster in the near-earth plasma sheet through application of the grad-shafranov (gs) technique to reconstruct the transverse magnetic field distribution perpendicular to the flux rope axis at x=-14.75 re. we find that the principal axis of the flux rope lies approximately along the dawn-dusk direction and that the diameter of the flux rope is about 1.5 r(e). there is a strong duskward core magnetic field in the center of the flux rope. according to the ae index, there is no obvious sub-storm associated with the magnetic flux rope. recent studies indicate that the formation of the flux rope in the plasma sheet can be understood in terms of simultaneous reconnection at multiple x-line points in the near-tail. the distribution of the transverse magnetic field on the cross section is the asymmetric circles, which requires that the reconnections at multiple x-line points occur. so our results also provide additional evidence for the occurrence of multiple-x line reconnection in the magnetotail. |
