文摘A reliable phenomenological analysis of superdeformed（SD）bands shows that the so-called "identical" SD bands in general may have different bandhead moments of inertia (δJ<sub>o</sub>/J<sub>o</sub>≥10<sup>-2</sup>). Because the dynamic moment of inertia J varies with ω much faster than the kinematic moment of inertia J, and the ω variation of moments of inertia may be quite different for various SD bands, under certain conditions a near equality of J （hence E<sub>γ</sub>） of two "identical" SD bands may occur in certain frequency range (|δE<sub>γ</sub>/E<sub>γ</sub>|=|δJ/J|～10<sup>-3</sup>), and the angular momentum alignments may appear to be approximately quantized. But the situation turns out to be different in other frequency regions. The present phenomenological analysis seems to be consistent with the configuration assignments made by the available microscopic theory in the framework of strong-coupling model. No pseudospin symmetry is involved in the present analysis.
