主　　题：polarized quark QCD 

摘      要：In the framework of dynamical parton distribution model,we obtain the polarized parton distribution functions from a QCD global analysis of the worldwide polarized deep inelastic scattering *** the analysis,we apply the DGLAP equations with parton-parton recombination *** the sea quarks and gluons are dynamically generated from QCD radiations processes,with the nonperturbative input comprising only the polarized valence quark distributions.
