摘要
The kinetics of plasma during the process of Petschek mode magnetic reconnection is studied based on a two-dimensional hybrid code. It has been found that the acceleration of particles inside the reconnection layer is highly anisotropy. Few particles are accelerated along field lines to a very high energy, while the bulk of the plasma remains in a relatively low velocity. We have pointed out that such a new picture of energy distribution in particles can be used to explain the formation of highly energized particle beams observed in space.
