Abstract：
According to the SU(3)_rf×SU(2)_s×SU(3)_c group classification theory,the total antisymmetric baryon wave functions are constracted, in which the mass difference between s quark and light (u,d) quark are considered. A comparison with the case of no mass difference between s and u,d quark is made. It is shown that the mass difference effect is not negligible in the interaction energy matrix elements.
