Abstract in English

The solution of the leading log QCD evolution equation for the non-singlet evolution function is given in the form of a convergent series. The convergence is rapid for small values of x. An asymptotic expansion in powers of (1 - x) is also obtained. Its first few terms reproduce within about one per cent all the moments of the evolution function in the kinematical range of present and near future interest. Using simultaneously the two expansions it is easy to calculate structure functions in all the region 0 < x with an accuracy of the order of one per cent.
