刚柔耦合多体机械系统动力学微分方程组具有刚性和高频振荡的特点。

The dynamical equations of rigid flexible coupling multibody systems have characters of stiffness and high frequency oscillation.

结果表明：准两年振荡是线性海气耦合系统中的最不稳定模态，且只有该模态类似于ENSO水平结构。

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.
