摘要：

Random percolative disorder has been introduced into 300 x 300 arrays of Nb-Au-Nb proximity-coupled junctions. Our measurements of dc transport properties show that large amounts of random disorder, although depressing T(c) and broadening the resistive transition, do not alter the scale invariance of the phase transition. These results are described by a model which rescales the Josephson lattice by the percolation correlation length. The relevance of the observations to granular thin films is discussed.
