A sets of transforms are introduced in this dissertation , by using of which some kinds of topographies , such as continental slope and ridge , can be converted into flat bottom . the processing simplifies the generation of internal tides and reflection of internal waves over those kinds of topographies 针对海洋中的一些地形,如陆架陆坡地形、海山地形、海沟地形,提出了一组坐标变换,该变换可以将这些海底地形变换成平底,从而使得在这些特征地形上内波的传播和内潮的产生问题得到很大的简化。
One dimensional equation can be obtained through extending the stream function and forcing term into fourier series , and this equation can be solved by assuming the traveling - wave solution . besides converting the topographies to flat bottom , the transforms also change the distribution of forcing . for subcritical topography , the intensity of 所用的求解方法为将解和强迫项在变换平面内进行付里叶级数展开,得到一维的波动方程,通过设行波解的方法求解该一维波动方程,所有模态解的叠加即为内潮生成问题的解。
