  The character of the behavior of the RGE constant on a certain energy
interval is studied and polynomial interpolation is carried out to obtain an
analytic function describing the RGE constant in QCD. A graphical description
of the nature of the dependence of the beta function and the interaction
constant is carried out and it is shown that a good agreement with the
theoretical predictions of the asymptotic freedom is observed only in the
energy region of 3800-4000 GeV.
