| 摘 要： | 运用小振幅波理论对三层成层水域的内波运动进行了解析，推导出三层成层状态下界面内波的基本方程和定解条件，得到了一阶近似方程的色散方程．并分析了密度和深度变化对水平波数的影响，得到了三层水域中存在大小2种波动方式．因此得到的结果对合理选择工作地点和水深，避免因内波可能产生的大振幅运动带来的损失有一定的作用．

| Abstract: | The basic equation and boundary condition of the inner wave in the three-layer ocean are analyzed by small amplitude wave theory in this paper,calculates the dispersion relation in three-layer ocean by the fact.It exists two kinds of motion in three-layer ocean by though analyzing this example.This trait is helpful to choose the right depth and to avoid the loss by the large effect of the inner wave. |
