摘要：

The one-dimensional Kondo-necklace model is investigated on the basis of bosonization. We prove that the model belongs to the same universality class as the one-dimensional half-filling Kondo lattice model at operator level, furthermore, the excitation and the gap formation are derived. We suggest that the spin gap of this model always exists for all finite J. (C) 1998 Elsevier Science B.V.
