Аннотация:The noise-induced transport of a Brownian particle with regard to its mass is considered. The results of approximate analytical calculations for the averaged probability flux in periodic ratchet-like potentials are presented. The influence of the potential shape on the mean particle velocity is traced. In the case of sufficiently small particle mass, it is shown that with increase in mass the reversal of flux is possible.
