Generally speaking missile is always underdamping .

一般导弹都是欠 阻尼的。

The general solutions for the free vibration of underdamping critical damping overdamping of cylindrical laminates was simply given in terms of the linear damp vibration theory .

依据线性阻尼振动理论，简要地给出了 开口层合壳的 欠 阻尼、临界阻尼和过阻尼 等 三 种自由 运动的通解公式。
