我们报告的观测Geotail卫星显示，大坡印亭通量与阿尔芬波在等离子体片边界层（PSBL）发生在附近的近尾重联区1996年12月10日。在大坡印亭通量期间，Geotail还观察到强烈的尾部等离子体流。这些观测结果表明，近尾重联过程的重要性，作为能源的阿尔芬波在PSBL。强尾向（向地）等离子体流应该是产生阿尔芬波的一个重要候选者。此外，PSBL中观察到的不仅是磁场而且是电场的强扰动表明PSBL在与Alfven波相关的能流的产生和传播中起着重要的作用。
We report observations from Geotail satellite showing that large Poynting fluxes associated with Alfven waves in the plasma sheet boundary layer (PSBL) occur in the vicinity of the near-tail reconnection region on 10 December 1996. During the period of large Poynting fluxes, Geotail also observed strong tailward plasma flows. These observations demonstrate the importance of near-tail reconnection process as the energy source of Alfven waves in the PSBL. Strong tailward (Earthward) plasma flows ought to be an important candidate in generating Alfven waves. Furthermore, the strong perturbations not only of the magnetic field but also of the electric field observed in the PSBL indicate that the PSBL plays an important role in the generation and propagation of the energy flux associated with Alfven waves.
