使震动

In this paper, we propose a new semi-active variable stiffness damper which offers two stiffness to the controlled structure and can keep the structure in nonresonant condition.

设计出一种新型主动变刚度阻尼装置，该装置可向受控结构提供两种等效刚度，使受控结构能主动地避开地震动卓越频率而永远处于非共振的状态。

"The reason these guitars sound so good is because of how much they're vibrating,"Smith explains.The whole idea was to make them as loud as they can possibly be , put a nice balance between treble,midrange and bass, and have the bass not sound woofy when miked.

吉他声音好的原因主要是他们的震动很好，Smith解释说使这些吉他的声音尽可能的是一个整体，在高中低音重有好的平衡而且拾音的时候低音没有那么的密。

This could eventually destabilise the financial markets and potentially put the lending activity out of CBRC's control.

As a new-fashioned solid state lighting source, LED has many unique advantages such as nearly no pollution of the product and in the production process; resistance to vibration; easily dimmering from 0 to 100%; operating under safe extra low voltage; continuously operating under the condition of switch-off; having a fixed direction of the light output etc. In recent years, LED's obvious improvement of luminous efficacy and photometric characteristic let it be applied for commercial purpose.

LED作为一种新颖的固体照明光源，具有生产过程以及产品几乎无污染，不怕震动，可轻易实现0~100%的连续调光，能在安全特低电压下工作，可连续工作于开关闪断的工作状态以及其光输出具有定向性等诸多独特的优势，近年来在其光效和光色上的明显进步已使它能进入商业化应用。
