摘要：
In this paper we present the results of our QCD analysis for non-singlet quark distributions and structure function F-2(x, Q(2)). New parameterizations are derived for the parton distribution functions for the kinematic wide range of x and Q(2). The analysis is based on the Jacobi polynomials expansion of the structure function. Higher twist effects is take in to account in our QCD analysis also. Our calculations for non-singlet quark distribution functions based on the Jacobi polynomials method are in good agreement with the other theoretical models.
