Аннотация:We have obtained the time dependence of the mean square displacement of a Brownian particle in the presence of randomly distributed traps in the one-dimensional case. It turned out that deviations from the traditional relation 〈 x2(t) 〉tr=2Dt occur as early as the initial stage of the process.
