Abstract: We discuss solution of QCD evolution equations and
their application to analysis of experimental data about neutrino scattering
on nuclei. We consider, in particular, the so-called non-singlet quark
distribution function in nucleons in the leading order using the method of
numerical inverse Mellin transformation. Parameters specifying the needed
boundary conditions are determined by fitting data of the CCFR experiment
in Fermilab. In addition to these parameters we determine also the value
of the basic QCD parameter Lambda.
