摘要：
Based on the hadronic level, the value range of the surface gravitational redshift of the neutron star PSR J1614-2230 is tried to be determined in the framework of the relativistic mean field theory. It is found that for the neutron star PSR J1614-2230 the ratio of mass M and radius R is in the range of similar to 0.1692 to 0.1958 and the surface gravitational redshift is in the range of similar to 0.4138 to 0.5397. However, for a small mass neutron star, which is calculated with the hyperon coupling constant obtained by the constituent quark model [SU(6) symmetry], the ratio of mass M and radius R is 0.1221 and the surface gravitational redshift is 0.2507. The surface gravitational redshift of the neutron star PSR J1614-2230 is about one times larger than that of the small mass neutron star. DOI:10.5506/APhysPolB.44.211
