摘要
In the recent decades,great attention has been paid on the heavy ion collisions under intermediate energy^([1～4]).Early studies mainly focused on the nuclear collisions under low and high energy^([5,6]).In low energy nuclear collisions,the behavior of the colliding nuclei is determined by their mean field,while in high energy nuclear collisions it is the collision of individual nucleons in the nuclei that determines the outcome of the reaction.
