摘要：

We review recent numerical simulations of several models of interface growth in d-dimensional media with quenched disorder. These models belong to the universality class of anisotropic diode-resistor percolation networks. The values of the roughness exponent alpha = 0.63 +/- 0.01 (d = 1 + 1) and a = 0.48 +/- 0.02 (d = 2 + 1) are in good agreement with our recent experiments. The values of alpha in higher dimensions (alpha = 0.38 +/- 0.03 in d = 4 and alpha = 0.27 +/- 0.05 in d = 5) do not support a recent theoretical conjecture.
