摘要：

We consider diffusive motion on a periodic, anisotropic potential. Adding a zero-average force that fluctuates between three values: -F, 0 and +F, can bring about net flow. As the frequency of the fluctuations varies the direction of the flux can change. We discuss a possible application for the construction of a device to separate macromolecules.
