摘要：

The quark-meson coupling (QMC) model due to Guichon is formulated on the basis of the independent quark model of the nucleon proposed by Bogoliubov and is applied to the phenomenological descriptions of symmetric and asymmetric nuclear matter. For symmetric matter, the model predicts, at saturation density, the incompressibility K = 335.17 MeV, the quark effective mass m(q)* = 238.5 MeV and the effective nucleon mass M* = 0.76 M, where M is the nucleon mass in vacuum. Neutron star masses above two solar masses are obtained.
