The numerical simulation are consistent with the analytical results contained in chapter 2. In chapter 4, Mapping and chaos .We plot poincare cross-sections, the results illuminate that the two electrostatic waves which satisfy the resonant criterion found in this paper have more effective stochastic acceleration than nonresonant condition.
