Abstract：
The superdeformed bands of the even-even nuclei in A～190 region are investigated thoroughly. The observed transition energies are fit to the ab expression to assign the spins with success for most of them provided the influence of the ΔI=4 bifurcation is estimated and removed properly from the r transition energies. For some superdeformed bands the assigned spins obtained in this paper are different from those given by other approaches.
