Abstract：
The equations of state of the neutron star matter are calculated in the relativistic mean-field approximation with different couplings of the hyperons.The properties of neutron stars are studied by solving the Oppenheimer-Vollkoff equation.It shows that these properties change distinctly as different couplings of hyperons are concemed.
