摘要：

An overdamped particle moving in a periodic potential, and subject to a constant force and a stochastic force (i.e., x = -sin(2pix)+B+GAMMA(t), GAMMA(t) is a white noise) is considered. The mobility of the particle, d<x(t)>dt, is investigated. A stochastic resonance (SR) type of behavior is revealed. The study of the SR problem can be thus extended to systems without periodic force.
