摘要：
We present the next-to-next-to-leading order (alpha alpha(2)(s)) 8 corrections to the first moment of the polarized virtual photon structure function g(1)(gamma)(x, Q(2), P-2) in the kinematical region Q(2) >> P-2 >> Lambda(2) in QCD. We find that the alpha alpha(2)(s) corrections are about 3% of the sum of the leading (alpha) and the next-to-leading (alpha alpha(s)) contributions, when Q(2) = 30 similar to 100GeV(2) and P-2 = 3GeV(2).
