Abstract：
The superdeformed bands in the A-190 and 150 regions are systematically analyzed using four-parameter rotational spectra formula of Bohr-Mottelson's I(I+1) expansion. The result shows that the superdeformed bands in the A-190 and 150 regions can be described very well with four-parameter ABCD-formula. The theoretical values of J⁽²⁾ of most of nuclei accord with the experimental extracted values. The four-parameter value relation doesn' t support the theoretical expected values of ab and Harris formula, but comparatively the theoretical expected value of ab formula agrees with the experimental extracted values better than that of Harris formula.
