We have simulated the Giant Dipole Resonance by QMD model in the low energy nuclear collisions with different incident projectile 40,44,48,52Ca with isospin asymmetry N/Z, studied the properties of GDR spectra and their dependence on the potential parameters, isospin asymmetry of the incident projectile, and the symmetry coefficient used in EOS, results show that GDR is an sensitive observable on isospin asymmetry and symmetry energy.We also study the Pigmy Dipole Resonance (PDG) in experiment by other groups, proposed that QMD can also be used in the PDR simulation and PDR can also be used to extract information for symmetry energy and isospin asymmetry in EOS.
