摘要: We present the results of our QCD analysis for nonsinglet unpolarized quark distributions and structure function ${F}_{2}(x,{Q}^{2})$. New parameterizations are derived kinematic wide range $x$ ${Q}^{2}$. The is based on Jacobi polynomials expansion function. higher twist contributions proton deuteron obtained in large region. Our calculations distribution functions method good agreement with other theoretical models. values ${\ensuremath{\Lambda}}_{\mathrm{QCD}}$ ${\ensuremath{\alpha}}_{s}({M}_{z}^{2})$ determined.
