In this paper, the interaction of a single wave with the transit particles in a toroidal plasma is discussed. When the wave amplitude is very low, a stochastic region may exist localized in phase-space in the vicinity of phase velocity of the wave. The velocity diffusion, current drive and wave absorption will result.
