摘要

在海洋运输、运动和能源领域，深海波浪动力学是海洋科学的主要问题之一。通过对两层分层条件下深海孤波动力学的数学建模，可以得到 NLS 方程，进而可以用耦合 NLS 方程来表述二者的相互作用。本文采用扩展辅助方程和exp(-ϖ(χ))展开方法来求解耦合NLS方程的Manakov模型的光学解。本文使用的方法除了提供单个波解的分析之外，还提供了一般光学解。一些以前已知的解可以通过求解代数方程系统获得的一些特殊参数选择来获得。在现阶段，采用符号计算系统的方法更为实用和方便。

Manakov model of coupled NLS equation and its optical soliton solutions

In the field of maritime transport, motion and energy, the dynamics of deep-sea waves is one of the major problems in ocean science. A mathematical modeling of dynamics of solitary waves in deep sea under the two-layer stratification leads to NLS equation, and consequently, the interaction two of them can be formulated by coupled NLS equation. In this work, extended auxiliary equation and the $e x p (- ϖ (χ))$ -expansion methods are employed to make the optical solutions of the Manakov model of coupled NLS equation. The methods used in this paper, in addition to providing the analysis of individual wave solutions, also provide general optical solutions. Some previously known solutions can be obtained by some special selections of parameters obtained by solving systems of algebraic equations. At this stage, it is more practical and convenient to apply methods with a symbolic calculation system.
