英文摘要The difference between the transition density of a larger mass hyperon star (for example, the neutron star PSR J1614-2230) and that of a smaller mass hyperon star is investigated in the framework of the relativistic mean field theory. We see that the transition density rho(0H) increases with the increase of x(omega) (i.e. the mass of the neutron star.). For the nucleons parts, the neutrons make the main contribution to the transition density as the baryon density rho=rho(0H). With the increase of the x(omega) (i.e. the mass of the neutron star), the relative particle number density of neutrons decreases while that of protons increases. For the parts of hyperons, the Lambda and Xi(-) make the main contributions to the transition density as the baryon density rho=rho(0H). The relative particle number density of Lambda decreases while that of Xi(-) increases with the increase of the x(omega) (i.e. the mass of the neutron star). For the hyperons Sigma(-), Sigma(0) and Sigma(-) the total contributions are less than 16 per cent.
