The results show that the chiral symmetry is restored partially when the strange matter density increases and 2 plays a very important role in the strange matter which may approach the constituents of the neutron stars. in additions, we can find that the strange matter density where the - condensate emerges is led to the ratio of the nucleon number to baryon number. and the occurrence of - condensate is only in certain density and gradually increases for higher density, so we guess that - field may be necessary to carefully consider for studying the neutron stars
