Abstract：
Status of the investigation on superdeformed nuclear bands are surveyed briefly.An algebraic model which can describe the ΔI=4 bifurcation and the identical bands is proposed.The calculated results indicate that the ΔI=4 bifurcation may come from the perturbation holding the SO(5)(or SU(5)) symmetry.Meanwhile the identical bands result from that the mean field for the superdeformed bands to build upon may possess supersymmetry.
