摘　　要：As we know that in fact, nuclei offer an interesting isospin situation, where symmetry potential, Coulomb interaction and isospin dependent in-medium nucleon-nucleon collisions are simultaneously present. But, in general, the isospin effects of Coulomb interaction is not studied separately in more detail, even though the studies for the isospin effect of the isospin dependent mean field in the heavy ion collisions include automatically the role of Coulomb term. However the Coulomb interaction is an important asymmetry term, which can bring important isospin effect into the observable in the intermediate energy heavy ion collisions. The study for the role of Coulomb interaction on the isospin effects of observable in intermediate energy heavy ion collisions, is important for exploring isospin physics and setting up the equation of state for the isospin asymmetry nuclearmatter.
