Abstract：
The spin values of the superdeformed (SD) bands in A≈190 region have been assigned by comparing the fitting results of Bohr-Mottelson and Harris formulas.The assigned spin values in most of the SD bands are consistent in the both fitting results. For the superdeformed bands whose spin cannot be assigned consistently by the two formulas or the bands whose spin assignment doesn't accord with bandhead moments of inertial systematics, we assign their spin using moments of inertial systematics. By using our assigned spin values, the relation of parameters of Bohr-Mottelson formula has been examined. The results show that the relation deduced from three-parameter Harris formula is closer to the experiment than the relation deduced from ab formula.
