| Abstract: | In this paper, the analytic expressions of polarized distributions functions of valence quarks depending on Q2 in the nuclson is obtained by Mell in transformation of A-P equations and the expansion of the Mellin transformational results of evolution functions Using the results obtained in this paper, some predictions for quark spin asymmetry in the nucleon is also given. |
