1·A piezoceramic vibrator has infinite number of vibration modes, but usually only one or a few of them are used and all the other undesirable modes must be suppressed.
一个压电陶瓷振子含有无限个振模,而常常应用其一个或数个,对于其它不需要的模式,必须加以抑制。
2·In this thesis, the application of piezoceramic (PZT) impedance analysis approach in structure health monitoring is studied.
本文研究了压电陶瓷(PZT)阻抗分析法在结构健康监测中的应用。
