Average Multiplicities in Gluon and Quark Jets in Higher-Order   Perturbative QCD
  The ratio of average multiplicities in gluon and quark jets is shown to become noticeably smaller in higher-order QCD compared to its lowest order value what improves agreement with experiment.   QCD anomalous dimension has been calculated. It has been used to get energy dependence of mean multiplicities.
