摘要：

We study a three-dimensional classical XY model with strongly fluctuating, spatially uncorrelated, bond disorder. Finite-size scaling analysis of Monte Carlo simulation data has been used to determine critical exponents. Evidence for a possible shift in exponents from the pure XY case is found. Connection to recent experiments on the superfluid phase transition of He4 in porous media is discussed. © 1990 The American Physical Society.
