  We apply the theory of Takahashi and Tachiki in order to explain
theoretically the dependence of the upper critical magnetic field of a S/N
multilayer on the temperature. This problem has been already investigated in
the literature, but with a use of an unphysical scaling parameter for the
coherence length. We show explicitely that, in order to describe the data, such
an unphysical parameter is unnecessary if one takes into account the boundary
resisitivity of the S/N interface. We obtain a very good agreement with the
experiments for the multilayer systems Nb/Cu and V/Ag, with various layer
thicknesses.
