摘要：

We study analytically and numerically the reaction kinetics for diffusion-limited reactions of the type A + B(static) --> C(inert) in one-dimensional (1D) systems with reactants initially separated in space. We find expressions for the concentration profiles of each species, and for the reaction front. The width of the front is characterized by w approximately t(alpha) with alpha = 1/4, and its height by h approximately t(-beta) with beta = 3/4; these values differ from the "mean-field" exponents and from those obtained when both species diffuse.
