Random dispersion map is considered in a dispersion-managed dark soliton system, its influence on soliton propagation and interaction is discussed. It is found that the random dispersion map results in large sidebands, leads to submergence of dark soliton, and enhances the interaction between solitons. Finally, nonlinear gain is introduced to suppress the influence effectively.

“未来世界会变得更好吗”,关于这个问题的思考与讨论是当今许多科幻电影所热衷的主题。随着科技与工业的不断发展,人们对于自然的利用与改造已经变得十分广泛和深入,人类的物质生活也因此有了极大的提高。然而,对大自然肆无忌惮的索取与不计后果的开发也使得人类遭遇了前所未有的恶劣环境与生态危机。  所以,在科幻电影中,经常会出现环境极端恶劣的未来世界。在2014年热映的美国科幻电影《星际穿越》中,我们的未来世界
