  The transport phenomenon (movement and diffusion) of inertia Brownian
particles in a periodic potential with non-Gaussian noise is investigated. It
is found that proper noise intensity Q will promote particles directional
movement(or diffusion), but large Q will inhibit this phenomenon. For large
value of Q, the average velocity V (or the diffusion coefficient D) has a
maximum with increasing correlation time tau. But for small value of Q, V (or
D) decreases with increasing tau. In some cases, for the same value of Q and
the same value of tau, non-Gaussian noise can induce particles directional
movement(or diffusion), but Gaussian colored noise can not.
