【 摘 要 】

The propagation of dust ion-acoustic nonlinear periodic (cnoidal) waves is investigated in an unmagnetised dusty plasma characterised by a non-thermal electron population. The equations describing the dynamics of the wave potential in the first and second orders of perturbation theory are derived, and their nonsecularperiodic solutions are found. The average nonlinear ion flux caused by the propagation of a cnoidal waveis determined. The nonlinear ion flux is found to depend significantly on dust concentration and non-thermalityparameter.
