Abstract：
By using the Generator Coordinate Method (GCM),the continuous variables representation of IBM (s,p,d) has been derived and discussed in this paper.The calculated splitting of giant dipole resonances (GDR) is close to 3MeV in deformed nuclei.The ratio of dipole strengths to the longitudinal and transverse components is less than 2.
