说明：  为了更好的研究振动， 下面我来说说阻尼吧， 因为阻尼在振动过程中是十分 重要的， 所谓阻尼是指用来衡量振动系统本身消耗振动的能力的物理量。 由于阻 尼的存在使得一些工程构件在机械振动过程中， 一部分能量转化为其它形式的各 种能量，如热能等。现在许多科学家都研究过阻尼产生的原因，但由于有些阻尼 生成机理过于复杂， 因而其原因至今尚不清楚的被人们所熟知。 实际的振动系统 往往是多种阻尼的交互作用， 这导致了它的难分析性。 实际分析中阻尼往往被做 线性化处理，这是由于线性系统可以很好的模拟实际问题。
(In order to study vibration better, let me talk about damping, because damping is very important in the process of vibration Important, the so-called damping refers to the physical quantity used to measure the ability of vibration system itself to consume vibration. Due to the existence of damping, a part of the energy is transformed into other forms of energy, such as heat energy, in the process of mechanical vibration of some engineering components. At present, many scientists have studied the causes of damping, but the mechanism of some damping is too complex, so the reason is still unknown. The actual vibration system is often the interaction of multiple damping, which makes it difficult to analyze. In practical analysis, the damping is often linearized because the linear system can well simulate the actual problems.)
