In connection with the semi-inclusive polarized DIS, it is proposed to consider the first Melin moments Δq of the polarized quark and antiquark densities, instead of the respective variables δq(x), local in Bjorken x themselves. This gives rise to a very essential simplification of the next to leading order (NLO) QCD and, besides, allows one to use the respective QCD sum rules. An expression for Δu-Δd in NLO is obtained which is just a simple combination of the directly measured asymmetries and of the quantities taken from the unpolarized data.
