Abstract
We apply a recently introduced non-perturbative renormalization method to two types of lattice operators: the Delta S = 2 four fermion opera tor and the heavy-light static axial current, which are relevant for t he physics of K and B mesons respectively. The results of the non-pert urbative calculations of the renormalization constants are compared wi th the corresponding perturbative ones.
