摘　　要：By perturbative calculations of the high temperature ground-state axial current in intrinsic regularization,an anomalous Chern-Simons topological mass term is induced in the three-dimensional effective action.The anomaly in three dimensions appears just in the ground-state current rather than in the divergence of ground-state current.In the abelian case,the contribution comes only from the vacuum polarization graph,whereas in the nonabelian case,contributions come from the vacuum polarization graph and the two triangle graphs.
