摘　　要：孤子对(如亮暗孤子对和暗-反暗孤子对)可以产生很多新奇的现象,它们对深入理解非线性系统的物理性质起到了重要的作用.本文通过数值模拟的方法,考虑了三次非线性、自旋轨道耦合、塞曼能级分裂等,对一维孤子对的产生机制和稳定性进行了研究.Soliton pairs,such as the dark-bright solitons and dark-anti-dark solitons,feature a lot of novel phenomena,and play an important role in understanding the physics of nonlinear systems.The effect of cubic nonlinearity,as well as the spin-orbit coupling and Zeeman splitting,are considered in this paper to study the mechanism of the creation of one-dimensional soliton pairs and their stabilities by the mean of numerical simulations.

关 键 词：孤子对 三阶非线性 自旋轨道耦合 塞曼分裂
