摘要We study a recently introduced stochastic growth model for interfacial depinning with quenched disorder in
111 dimensions. We numerically investigate the dynamic correlations of the interface roughening process by
studying the qth order equal-time height difference correlation functions. We find that this system does not
consist of multiscaling behaviors, in contrast to the molecular-beam-epitaxy motivated growth models with
annealed noise, although it does exhibit anomalous dynamic scaling and spatiotemporal intermittency. Moreover, we also investigate the influence of different boundary conditions on the global width of the system. For
small system sizes, the discrepancy between the obtained global widths with different boundary conditions will
moderately alter the value of the roughness exponent. We propose a modified definition of the global width and
quantitatively show that this modified definition is more universal for the systems with different boundary
conditions and, thus, more applicable to the experimental measurements. @S1063-651X~99!10001-1#
