中文摘要：

讨论PT对称Scarf-Ⅱ势中孤子的散射问题,包括演化动力学以及PT对称Scarf-Ⅱ势对孤子单向散射的影响。在此基础上,给出实现单向孤子流的孤子初始速度窗口、势实部的深度、势虚部的宽度和深度的窗口。结果表明适当选取初始速度v0、势函数的实部深度V0以及虚部深度W0和宽度x2,可以找到孤子向左或者向右的单向流,由此可以实现对单向孤子流的操控。

Abstract：The soliton scattering in PT-symmetry Scarf-Ⅱ potential is discussed by numerical stimulation,including the evolution dynamics and the influence of PT-symmetry potential to soliton unidirectional scattering properties. Based on these results, we present the incident velocity window, the width and depth window of the imaginary part of the potential. The results show that the soliton scattering can exhibit the properties of the unidirectional flow and manipulate the scattering direction of the soliton by choosing some proper the potential parameters.
