摘要：

For the first time a next-to-next-to-leading order analysis is performed of the deep inelastic structure functions F2 and F(L) using the recently determined first moments of the non-singlet anomalous dimensions and the corresponding Wilson coefficients. From a comparison to BCDMS data we found a slight decrease in the energy scale of perturbative QCD with respect to the next-to-leading order analysis, which brings the scale closer to the value predicted from a scheme-invariant approach.
