摘要：

It is shown using large-scale simulations that the density profile in diffusion-limited aggregation in two dimensions satisfies a scaling form (multiscaling) of the type g(r, R) = r(-d+D(r/R))C(r/R), where r is the distance from the origin, R is the radius of gyration, and C(x) is an amplitude. Contrary to standard scaling, which predicts D(x) = const, here D(x) is found to depend continuously on x.
