摘要	The most general model with a magnetic impurity coupled to hybridizing and screening channels of a conduction band is considered. The partition function of the system is asymptotically equivalent to that of the multicomponent kink plasma with a weak external field. The scaling properties of the models for finite U are sketched by using the Anderson-Yuval-Hamann-Cardy poor-man's scaling theory. We point out that it is proper to include a two-body hybridization in order to obtain correct renormalization flows. The phase structures are studied graphically for the general model and various reduced models. A Fermi-liquid-non-Fermi-liquid phase transition is found for all the models. We also show all possible phases with different finite-temperature behaviors though they have the same Fermi-liquid fixed point at low temperature. We also discuss the fixed-point behaviors in the mixed-valence-state regime.
