充气机翼的颤振形式除常规的弯扭模态耦合外，弦向弯曲模态同样会发生颤振；
Except for the typical bending and torsion modes, the chord-wise bending modes have low frequencies.
在两个频率成分的间隔小于一定值，相邻频率成分产生严重模态耦合时，不能使用这种方法。
If the interval between frequencies is reduced to a certain value, the coupling will be so severe that this method can not be used.
在两个频率成分靠的较近，但产生的模态耦合不严重时，通过二次校正可以降低耦合影响，提高估计精度。
When one frequency is close to the others and the coupling is not very severe, we can enhance the precision by the second correction.
