摘要：
By using the partial wave method, we investigate the absorption of Dirac field from the Bardeen regular black hole. We numerically carry out the absorption cross section, we find that the larger angular momentum quantum numbers l are, the smaller the corresponding maximum values of partial absorption cross section are. When the magnetic monopole charge beta increases, the absorption cross section and the power emission spectra of Hawking radiation increase, but the absorption probability and the luminosity decrease.
