摘 要：Analysis on electrostatic solitary waves(ESWs)observed in the upstream and downstream of the slow-shock near the magnetic reconnection diffusion region is *** show that the ESWs propagate outwards in the upstream region while inwards in the downstream *** amplitude of ESWs in the downstream is more than 6 times those in the upstream,suggesting that energy outwards from reconnection X-line is much larger than ***,observations show,that electron beams associated with ESWs,which are parallel to ambient magnetic are much stronger in the downstream than in the upstream region of slow *** of electron beams in both upstream and downstream are coherent with the propagation directions of *** are consistent with the generation mechanism of ESWs which are suggested to be related to electron *** result is helpful for solving the issue of ESWs’generation mechanism associated with magnetic *** also provides an important hint for the understanding of fast energy release during the magnetic reconnection process.
