    In this article we give some powers δα (x), Re α >1/2, a definite meaning, using;the sequential approach of distributions; the regularization of divergent integrals and the idea of fractional derivatives, especially expansions containing fractional derivatives and powers (2.4). Our main result is the followingTheorem 2.1. For Reα <1/2 the power δα(x) is well defined on the idealsubring of the space D(R) of infinitely differentiate complex-valued functions with compact support in the following wayIf α is such that yt is an odd function of y, then Cα = 0; hence εα = 0.Using this result, we can affirm relations(l.l) in quantum mechanics and give the δ-sequence(2.1) a canomical meaning.We give the product δ(x)lnδ(x) a definite meaning too.In higher dimensional case the discussion is similar. It would be interesting to provein the case 0≤Reα≤l, where is the fractional integral of φ.More propably, the ideal subring Dk-1, on which the power δα(x) is applied, may be a restriction and description to elementary particles in quantum field theory.It is emphasized that the power δα is an entity as a whole and that
