摘要：

We present numerical evidence for the existence of two distinct universality classes characterizing driven interface roughening in the presence of quenched disorder. The evidence is based on the behavior of lambda, the coefficient of the nonlinear term in the growth equation. Specifically, for three of the models studied, lambda --> infinity at the depinning transition, while for the two other models, lambda --> 0.
