摘　　要：首先概述了对A≈150区超形变带的自旋指定的进展情况,到目前为止,所提出的各种方法对该区超形变带自旋值的指定并不一致．发现了该区超形变带的实验能谱特性和动力学转动惯量的特性．并将此特性用于指定A≈150区超形变带的自旋．In the previous publications, the assignments of spin values of the superdeformed bands in A ≈150 region are not consistent by different methods. In the present work, through systematical comparison and analysis of the experimental energy spectra of the superdeformed bands in this region, we obtained two formula to describe the energy spectra and moments of inertial.Using the formulas, we assigned the spins of the superdeformed bands for several nuclei in A ≈150 region.
