经管路模型试验和水泵机组试验证明，这两种隔振垫可使管路系统振动加速度级明显下降。
Through piping model test and pump unit trial it is shown that with the two types of isolating shims the vibration acceleration of the piping system can be reduced evidently.
振动用加速度有效值描述，噪声以声压级表示。
The vibration is characterized by the virtual value of acceleration, and the noise is indicated by the sound-pressure-level.
