  We present the results of our QCD analysis of the recent CCFR data for the
structure function $xF_3 (x,Q^2)$ of the deep-inelastic neutrino--nucleon
scattering. The analysis is based on the Jacobi polynomials expansion of the
structure functions. The concrete results for the parameter $\Lambda_{\overline
{MS}}^{(4)}$ and the shape of quark distributions are determined. At the
reference scale $|Q_0^2|$=3 $GeV^2$ our results are in satisfactory agreement
with the ones obtained by the CCFR group with the help of another method. The
$Q_0^{2}$-dependence of the experimental data for the Gross--Llewellyn Smith
sum rule is extracted in the wide region of high-momentum transfer. Within
systematical experimental uncertainties the results obtained are consistent
with the perturbative QCD predictions. We reveal the effect of the discrepancy
between our results and the analysed perturbative QCD predictions at the level
of the statistical error bars. The importance of taking account, in our
procedure, of a still unknown next-next-to-leading approximation of the moments
of the structure function $xF_3 (x,Q^2)$ is stressed.
