Using the three approaches for the spin assignment of rotational bands,the observed superdeformed (SD) bands of even even nuclei in the A～190 region are analyzed. For the yrast SD bands 194 Hg(1) and 194 Pb(1), the spin assignments agree with the experimental results.The spin assignments for the yrast SD bands of even even nuclei in the A～190 region by using the three approaches are consistent with each other and are believed to be reliable.
