主　　题：dusty plasma ratchet 

摘      要：Directional motion of dust particles in a dusty plasma ratcnet is observed *** dusty plasma ratcnet consists of two concentric gears with asymmetric *** is found that the sawtooth number affects the directional motion of dust particles along the saw *** the inerease of the sawtooth number,the particle velocity increases firstly and then decreases,and there is an optimum number of the sawtooth which could induce fast rotation of dust *** velocities of dust particles change as they are flowing along the saw *** also explore the force acting on the dust particle experimentally.
