| 摘 要： | 以差分法数值求解给定频率的特征值（波数），描述连续分层重力内波的传播模式，揭示出该内波的色散具有异向性的特征。采用内波差分特征值数值法对密度均匀分布流场进行求解，其解与表面行波解析法结果是一致的。 |

| Abstract: | n this paper the eigenvalue(wave number) is solved by the finite difference method when the value of frequency is given, the propagation model of the internal wave is described and the anisotropic character of the dispersive systems is illustrated. The numerical solution for unvarying density demonstrates that the simulated method is reliable. The fact that the numerical solutions agreed with the observetion shows that the method is feasibility. The study on the internal wave with continuous stratification is a new contribution to the perfection of the internal wave theory and its application after studying the inter facial wave. |
| Keywords: | internal wave continuously stratified fluid dispersive systems |
