摘要：
We have carried out dynamic simulations for Ising spin glasses on simple cubic lattices in dimension 3 with five different sets of near-neighbor interaction distributions. We find that the dynamic exponent in the power-law relaxation of the autocorrelation function at the ordering temperature varies considerably with the distribution chosen. This indicates that the standard universality rules do not appear to hold for these systems.
