Abstract：The event of high-energy electrons is an important phenomenon during magnetic reconnection.High-energy electrons are observed in several magnetic reconnection regions by spacecraft,such as Wind and Cluster.Based on the partially analytical expression of the particle dynamical equations and the result of Hall MHD computer numerical simulation,the decoupling between electron and ion in the region near X-line was studied in the case of X-type magnetic reconnection in this paper.The time-evolution characteristic of the magnetic field component and the speed component in the z-direction which is perpendicular to the reconnection plane was obtained in this region.Our results showed that the motion of electrons which played a dominant role was highly structured in the magnetic reconnection process.Affected by multiple factors,their velocities presented non-linear as well.The magnetic field component and velocity component in the z-direction were with inflection points.There were significant differences between before and after the inflection point in the aspect of wave characteristics of electric-field intensity.
