| 摘 要： | 根据一种三维潮致拉格朗日余流的弱非线性理论,考虑单一频率潮波系统,在零阶天文潮和一阶拉格朗日余流数值计算的基础上,计算了二阶拉格朗日余流,然后对8个具有代表性的标识质点运动轨迹进行了数值跟踪。对水平及垂直运动性质进行了分析,并用卫片资料对结果进行了验证。提出一些有启发性的初步结果。

| Abstract: | Based on a three-dimensional weakly nonlinear Lagrangian residual current theory and numerical calculation of zeroth-order tide and first-order Lagrangian residual current,the authors calculated the second-order Lagrangian residual current and the net displacements at eight sites The nature of the horizontal and vettical movement is analysed.Some computational results have been verified by satellite picture In the end,the authors present a few interesting results |
