摘　　要：Isospin dependent quantum molecular dynamics (IQMD) model is further developed by introducing switch function method which deals with correctly the surface interaction and shell effect in the process of projectile and target approaching. In the improved IQMD (ImIQMD), the time evolution of the nucleons in the system is governed by Hamiltonian equation of motion, and the Hamiltonian consists of the kinetic energy and the effective interaction potential energy. The effective interaction potential energy is composed of theIsospin dependent quantum molecular dynamics （IQMD） model is further developed by introducing switch function method which deals with correctly the surface interaction and shell effect[2] in the process of projectile and target approaching.
