震幅

传统二叶式鼓风机压力震幅大，造成震动及噪音缩短轴承、齿轮及其他的传动元件的寿命。

Conventional blowers result pressure pluses and vibration rob power and shorten the life of every bearing , gear and other drive train components .

日本平均每年会发生1500多次地震，不过好在震幅往往都不大，不会造成太大影响。

It experiences 1500 earthquakes every year . Thankfully , most of these quakes are just tremors . Japan is no stranger to devastating earthquakes .

半刚性连接兼有刚性和铰支连接的长处，可增加结构的阻尼，延长周期，减小震幅，从而降低震害。

Semi-rigid connection has the advantages of both the rigid connection and hinged joint , which can increase structural damping , lengthen period , and decrease vibrational amplitude , so that alleviate seismic hazard .

端板连接是一种具有一定柔性的连接形式，当结构采用这种节点时，可以增加结构的阻尼，延长结构自振周期，减小震幅，从而降低震害，是抗震的理想选择之一。

It is well known that end-plate connections have definite flexibility , which can increase damp , prolong period , and decrease swing of structure . So it can reduce the damage , and is one of best choices for resisting earthquake .
