导出二维三层（准三维）潮流与起伏地形相互作用而产生内潮波的非线性数学模型，并分别以Ｍ２分潮、Ｋ１分潮为策动期波，数值求解南海东北部大陆斜坡对策动潮波的响应。结果表明：台湾浅滩南面斜坡对Ｍ２分潮响应最为强烈，东沙群岛东面斜坡次之，其余海域无显著响应；对Ｋ１分潮的响应则以一统暗沙东南面斜坡最甚，其次为东沙群岛东南的斜坡，其余海域响应微弱。
The nonlinear mathematical model of internal wave generated by interaction between two-dimensional three-layer (quasi-three-dimensional) tidal current and undulating terrain is derived. The M2 and tidal K1 tidal wave are respectively used as the driving wave and numerical solution of the continental slope in the northeastern South China Sea Tidal wave response. The results showed that the south slope of Taiwan shoal had the strongest response to M2 tide, the east slope of Dongsha Islands was the second, and no response was observed in the remaining waters. The response to K1 tide was dominated by southeastern slope of the unified dark sand, followed by southeast of Dongsha Islands Of the slope, the rest of the sea response is weak.
