In this paper, the polarized structure functions of 3He and 3H nucleuses are calculated in the second approximation of Feynman diagram with considering symmetry and without considering it in light sea quark spin distribution of the nucleon. In order to do that the polarized structure functions of the nucleons in nucleuses are calculated at first through using Jacobi polynomials where polarized parton distributions of two different and confirmed phenomenological models are used which both SU(2) and SU(3) symmetries are broken in one of them. Finally the effective nuclear corrections are also considered. The results show that polarized nucleus structures of phenomenological model with symmetry breaking especially at small are in more consistent with the available experimental data.
