In earthquakes, it is very obvious for the structure-groundsill coupledoscillation.
在地震中,结构-地基耦合振动十分明显。

Through the border conditions of damping layer combined with the shell the coupledoscillation equation was solve, and radiation sound field expression was shown using the shell displacements.
通过阻尼层与壳体作用的边界条件求解流固耦合振动方程,解得辐射声场的表达式。

Results show that the quasi biennial (QB) oscillation is the most unstable mode of the linear coupled air sea system and only the QB mode displays ENSO-like horizontal structure.
