| 摘 要： | 在垂向动量方程中引入柯氏力的分量，即考虑在非静水压下的海洋波动，证明了只有当密度分层时，上述的柯氏力分量才对波动有影响，并且使得前传的内重力波速小于后传的波速，对于任意波数，内重力波速总是落在某一范围内。

| Abstract: | The term by Coriolis force in the vertical momentum equation is studied. Therefore it has to take into account non-hydrostatic effect caused by Coriolis force. It is found that Coriolis force generates internal waves due to small perturbation of density in stratified flows. Besides the phase velocity to the positive direction is less than that to the negative direction. For any specific wave number the phase velocity can be determined within a particular range. |
