First the feathers of vehicle hydraulic shock absorber vibration and sound is synthesized detailedly, classified as abnormal sound of friction attack, abnormal sound of resonance, abnormal sound of flow cutting and abnormal sound of gas.

首先对车辆液力减振器的振动噪声的特点进行了较为详细的分类和归纳总结，减振器异响分为：摩擦撞击异响、共振异响、截流异响和气体异响。

Then the transmission model of the active force was simpled as a single freedom vibration system to calculate the active force of aetuator.

将作动器的力传递模型简化为单自由度振动系统，计算了作动器的作动力，通过Matlab仿真软件对其力传递特性进行了仿真分析。

Then the transmission model of the active force was simpled as a single freedom vibration system to calculate the active force of actuator. The trans mission performance of the active force was simulated with Matlab simulation software.

将作动器的力传递模型简化为单自由度振动系统，计算了作动器的作动力，通过Matlab仿真软件对其力传递特性进行了仿真分析。

Besides, the vibrations of the valve body and poppet induced by the cavitating flow are detected using vortex displacement transducer, laser displacement meter and digital strain device.

实验同时采用涡流式位移传器，激光位移器和数字应变测量仪等构成的检测系统，研究了气穴流场诱发的阀体与阀芯振动。

The measurement model for the retardation distributing of the quarter wave plate was introduced by Muller matrix and Stokes parameter. And four patterns with phase shifting of 90°in turn were eatched simultaneously by an especial spatial splitting phase-shifter.

1／4波片相位延迟分布的动态测量，通过密勒矩阵和斯托克斯参量法对一种1／4波片的相位延迟分布的测量模型进行了推导，并设计出一种空间分光移相器，取代一般测量系统中的检偏器，使得系统能于瞬间同时采集四幅具有90°移相步长的干涉图，避免了环境振动对测量的影响，从而可以对1／4波片的相位延迟分布进行动态在线测量。

The speed with which the damper falls back on the string to stop its vibrations results from the speed with which the finger abandons the key; that is, if we raise the finger abruptly, the damper drops abruptly and stops the sound instantaneously.

制音器依靠弦来终止它振动的速度，就会产生一个手指离开键盘的速度；也就是，如果我们突然抬起手指，制音器就会突然地落下使得声音即刻停止。
