  We discuss Kondo effect for a general model, describing a quantum impurity
with degenerate energy levels, interacting with a gas of itinerant electrons,
and derive scaling equation to the second order for such a model. We show how
the scaling equation for the spin-anisotropic Kondo model with the power law
density of states (DOS) for itinerant electrons follows from the general
scaling equation. We introduce the anisotropic Coqblin--Schrieffer model, apply
the general method to derive scaling equation for that model for the power law
DOS, and integrate the derived equation analytically.
