Abstract：
The recent development of superdeformed identical bands are briefly reviewed. Some typical superdeformed bands are analyzed by the formula of Bohr-Mottelson's I(I+1) expansion. The results show that the dynamic moments of inertia J⁽²⁾ of so-called two identical bands are very similar, but kinetic moments of inertia J (1) and bandhead moments of inertia J₀ aren't equal. Signature partner bands are almost identical. Their J₀,J⁽¹⁾,J⁽²⁾ are almost identical respectively. Bohr-Mottelson Model is still one model which successfully explains the formation of identical bands.
