摘要：
Phenomenological parameterizations of proton and neutron polarized structure functions, g(1)(p) and g(1)(n), are developed for x greater than or similar to 0.02 using deep inelastic data up to similar to 50 (GeV/c)(2) as well as available experimental results on photo- and electroproduction of nucleon resonances. The generalized Drell-Hearn-Gerasimov sum rules are predicted from low to high values of Q(2) and compared with proton and neutron data. Furthermore, the main results of the power correction analysis carried out on the Q(2)-behavior of the polarized proton Nachtmann moments, evaluated using our parameterization of g(1)(p), are briefly summarized.
