Factorization of integrals, defining the beta-function, into integrals   of total derivatives in N=1 SQED, regularized by higher derivatives
  Some calculations in supersymmetric theories, made with the higher derivative regularization, show that the beta-function is given by integrals of total derivatives. This is qualitatively explained for the N=1 supersymmetric electrodynamics in all orders.
