Abstract：
By using the Hartree approximation which includes vacuum fluctuation correction in a model relativistic quantum field theory,it is found that the relativistic Landau parameters and the compressibility of the Fermi-liquid in the nuclear system,and the excitation energies of the giant monopole and quadrupole states are more close to the experimental values in comparison with the results of the mean-field theory.
