<正>After the discovered pulsars were identified as rotating magnetized neutron stars with an extremely large surface magnetic field of 1012-1014 G and - 1018 G could exist in the interior of star presumed from the scalar virial theorem, many scientists have investigated its origin and effects on the other properties of neutron star such as mass and radius. The neutron star is not of pure neutrons, it has a few percent protons as compared with neutrons. So, model, in which proton and neutron in dense nuclear matter behave
