摘要：
The isospin fractionation in heavy-ion collisions is investigated using a static method and an isospin-dependent quantum molecular dynamics (IQMD) model. A static interpretation of the isospin fractionation is provided based on a phenomenological asymmetric nuclear equation of state. The effects of different dynamic ingredients on the isospin fractionation, i. e. symmetry potential, Coulomb potential and isospin dependence of N-N cross section, are discussed in the frame of IQMD model.
