Abstract：
By utilizing the 1/N expansion technique,the SU(3)-symmetry breaking caused by boson energies is discussed for the sdg Interacting Boson Model,and the analytical expressions of the intrinsic states are given under the approximation in the order of 1/N.It is also shown that the many body theories for a interacting boson system,such as Hartree-Bose method.Tamm-Dancoff approximation and Cranked Hartree approximation,are all special cases of the 1/N expansion technique.
