摘要:
运用小振幅波理论研究了四层成层水域的内波运动,给出了四层成层状态下的各界面波波面位移和各层速度势的解析表达式及各层深度平均流速分布和内波波动频散关系,并与三层成层水域内波的解析结果进行了比较。

Study on internal wave in four-layer stratified fluid
Abstract:
In this paper, motions of internal waves in four_layer stratified fluid were investigated, and solutions of the elevations of the interfacial waves and the associated velocity potentials were presented based on small amplitude wave theory. Patterns of distribution of mean velocity due to the waves and its dispersion relationship were derived, and they are compared with the analytic results of the study on internal wave in three-layer stratified fluid.
Key words:  internal wave  four-layer stratified fluid  small amplitude wave theory
