| 摘要: |
| 内波作为一种发生在层化海洋内部的波动,在世界海洋范围内普遍存在。深入研究内波生成、演化等特性,对我国的海洋开发有着重要意义。针对两层及三层流体间内波理论,选取目前国内外广泛应用的KdV (Korteweg-de Vries)内波理论、MCC (Miyata-Choi-Camassa)内波理论、层析内波理论以及DJL (Dubreil-Jacotin-Long)内波理论综述其研究进展。从数学模型、理论研究以及数值模拟等方面,讨论了不同内波理论的优势以及局限性。从数学推导的角度,证明了MCC内波理论与第一级别层析内波理论是一致的。 |

| Abstract: |
| Internal waves, occurring in stratified ocean, are ubiquitous in the world oceans. It is of great significance for our country′s marine development to study the generation and evolution of internal waves. Based on the internal wave theory of two-layer and three-layer fluid systems, the KdV(Korteweg-de Vries) internal wave theory, MCC(Miyata-Choi-Camassa) internal wave theory, HLGN(high-level Green-Naghdi) internal wave theory and Dubreil-Jacotin-Long internal wave theory, which were widely used at home and abroad, were selected to review their research progress. The advantages and limitations of different internal wave theories were discussed from mathematical models, theoretical research and numerical simulations. In the view of mathematical derivation, it is proved that MCC internal wave theory is equivalent to the first-level HLGN internal wave theory. |
