The piezoelectric effect manifests itself as a transfer of electric to mechanical energy and vice-versa. 压电效应表明它自身具有将电能转换为机械能的能力，且反之同样适合。
By analyzing the torsional vibration of the tangentially polarized piezoelectric ceramic thin ring, electric terminals are calculated. 摘要通过分析接电负载压电薄圆环的扭转振动特性，推出机电等效电路和共振频率方程。
