摘要: In this paper, we investigate the Zakharov-Kuznetsov-Burgers (ZKB) equations for dust-ion-acoustic waves in dusty plasmas. Shock-like and soliton solutions are both constructed through introduction of an auxiliary function variable. ZKB-soliton propagation is plotted, from those figures, find that energy solitons increases when number electrons a dust particle decreases or mass such becomes larger. Considering external perturbations plasmas, study perturbed ZKB equation via some qualitative quantitative methods. To corroborate can indeed give rise to chaos, make use power spectrum Lyapunov exponents. Then, phase projections, weak developed chaos be observed. Weak occur absolute value damped coefficient (l1) stronger than strength term (g1), else, one occurs. Ranges l...
