欠阻尼、临界阻尼和过阻尼体系的典型位移-时间曲线

阻尼英语:damping)是指任何振动系统在振动中,由于外界作用(如流体阻力、摩擦力等)和/或系统本身固有的原因引起的振动幅度逐渐下降的特性,以及此一特性的量化表征。

在实际振动中,由于摩擦力总是存在的,所以振动系统最初所获得的能量,在振动过程中因阻力不断对系统做负功,使得系统的能量不断减少,振动的强度逐渐减弱,振幅也就越来越小,以至于最后的停止振动,像这样的因系统的力学能,由于摩擦及转化成内能逐渐减少,振幅随时间而减弱振动,称为阻尼振动。

Diffuse reflection

In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water attenuates both light and sound.
