摘　　要：Influences of crystal-fields （DA and DB ） and interlayer coupling interactions （J3） on dynamic magnetic critical behaviors of a mixed-spin （3//2, 2） bilayer system under an oscillating magnetic field are investigated by the Glauber-type stochastic dynamics based on the mean-field theory. For this purpose, dynamic phase diagrams are constructed in the reduced temperature and magnetic field amplitude plane for the ferromagnetic/ferromagnetic （FM/FM）, antiferromagnetic/ferromagnetic （AFM/FM） and AFM/AFM interactions in detail. We observe that the influences of DA, DB and Ja interactions parameters on the behavior of the dynamic phase diagrams are very much.
