We use the BLM procedure to eliminate the renormalization scale ambiguity inthe evolution equation for the non-singlet deep-inelastic structure function$F_2^{\text NS}(x,Q).$ The scale of the QCD coupling in the$\overline{\text{MS}}$ scheme has the form $Q^*(x) = Q (1-x)^{1/2} / x~f(x) $,where $x$ is the Bjorken variable and $f(x)$ is a smoothly varying functionbounded between 0.30 to 0.45. Equivalently, the evolution of the $n$th momentof the structure function should contain an effective $\Lambda_{\text{QCD}}$pattern, with $\Lambda_n \sim n^{1/2}$. This variation of $\Lambda_n$ agreeswith experimental data.Comment: 15 pages, RevTe
