摘要：

The double-exchange model in infinite dimension is studied as the strong Hund's coupling limit J-->infinity of the Kondo lattice model. Several quantities such as Green's function and the d.c. conductivity are calculated in analytical forms. Magnetoresistance in lightly doped La-?(1-x)SrxMnO3 is reproduced very well.
