摘　　要：The properties of neutron stars are studied in a relativistic mean-field model with SU(2) chiral symmetry spontaneous breaking being considered. The calculation results indicate that the effects of the chiral symmetry spontaneous breaking are not negligible.

关 键 词：neutron star chiral symmetry spontaneous breaking relativistic mean-field approximation
