摘　　要：Comprehensive records are available in ENA data of ring current activity recorded by the NUADU instrument aboard TC-2 on 15 May, 2005 during a major magnetic storm （which incorporated a series of substorms）. Ion fluxes at 4-min temporal resolution derived from ENA data in the energy ranges 50-81 and 81-158 keV are compared with in situ particle fluxes measured by the LANL-SOPA instruments aboard LANL-01, LANL-02, LANL-97, and LANL-84 （a series of geostationary satellites that encircle the equatorial plane at -6.6 RE）. Also, magnetic fields measured simultaneously by the magetometers aboard GOES-10 and GOES-12 （which are also geostationary satellites） are compared with the particle data. It is demonstrated that ion fluxes in the ring current were enhanced during geomagnetic field tailward stretching in the growth phases of substorms rather than after Earthward directed dipolarization events. This observation, which challenges the existing concept that ring current particles are injected Earthward from the magnetotail following dipolarization events, requires further investigation using a large number of magnetic storm events.全面记录在 NUADU 仪器在主要磁性的暴风雨期间在 2005 年 5 月 15 日在 TC-2 上记录的戒指水流活动的 ENA 数据是可得到的(它合并了一系列 substorms ) 。在时间的分辨率在 5081 和 81158 keV 与相比的精力范围从 ENA 数据导出的 4-min 的离子流动在 situ ，粒子流动在 LANL-01 上由 LANL-SOPA 仪器测量了， LANL-02 ， LANL-97 ，并且 LANL-84 (环绕的一系列地球同步的卫星在~的赤道的飞机 6.6 R <sub > E </sub>)。另外，磁场在 GOES-10 和 GOES-12 上由 magetometers 同时测量了(它也是地球同步的卫星) 与粒子数据相比。在戒指水流的离子流动在在 substorms 而非在向地的指导 dipolarization 事件以后的生长阶段拉长的地磁气的地 tailward 期间被提高，这被表明。这观察，它质问戒指水流粒子被注射的存在概念从 magnetotail 追随者 dipolarization 事件向地，用很多磁性的暴风雨事件要求进一步的调查。
