Abstract：
The superdeformed rotational bands in the A≈190 region are systematically analyzed using the Harris two-parameter formula and the ab expression, respeclively. Similar to the situations in normally deformed nuclei, there exist obvious and systematic deviation of Harris formula from the experiments, In contrast, the prediction of ab formula is very close to experiments, and can be conveniently used for the description of nuclear superdeformed bands.
