| 摘 要： | 本文主要是基于同时含有二阶和三阶非线性项的变系数Gardner方程对海洋内孤立波的传播特性开展研究。在吕宋海峡海域,展示了下降型海洋内波的传播特性及其在SAR图像上的信号特征,并着重分析讨论了耗散项和微扰项对海洋内波所引起的表层流速变化的影响。

| Abstract: | Utilizing the abundant analytical soliton solutions of the variable-coefficient Gardner including the quadratic and cubic terms,the propagation character of the internal waves in the Luzon Strait has been investigated.In the two-layer ocean system,the variation of signature characteristic for the depression internal wave on SAR image has been discussed.Furthermore,the effects of dissipation and perturbed terms on the internal waves and horizontal velocity of the ocean surface current has been presented. |
