摘要: A Brownian pump of particles in an asymmetric finite tube is investigated the presence unbiased external force. The pumping system bounded by two particle reservoirs. It found that can be pumped through from a reservoir at low concentration to one same or higher concentration. There exists optimized value temperature (or amplitude force) which capacity takes its maximum value. decreases with increasing radius bottleneck tube.
