摘　　要：简述了超形变原子核全同带的研究进展情况 ,并以Bohr Mottelson的I(I+ 1 )展开转动谱公式对部分典型的超形变带进行了分析 .发现所谓全同带的确只是两个带的J(2 ) 比较接近 ,它们的J(1) 和J0 并不相等 。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 J 0 aren't equal. Signature partner bands are almost identical. Their J 0,J (1),J (2) are almost identical respectively. Bohr-Mottelson Model is still one model which successfully explains the formation of identical bands.
