摘要
本文采用１／Ｎ展开技术，讨论了ＳｄＩＢＭ中由玻色子能量引起的ＳＵ（３）对称性玻缺，给出其１／Ｎ展开近似的内禀态解析表达式．
By utilizing the 1/N expansion technique,the SU(3)-symmetry breaking caused by boson energy is discussed for the sd Interacting Boson Model,and the analytic expressionsof the intrinsic state are given in the approximation order of 1/N.
