采用恒流驱动方法研究了锆钛酸铅陶瓷的振动能级特性。结果发现，共振频率和机械Q值显着降低，随着振动水平的增加，伴随着发热。发热被认为是由振动损失引起的。通过在陶瓷中掺杂Fe原子，降低了陶瓷的振动损耗。而Nb原子的掺杂则使振动损耗增大。
Vibration-level characteristics of lead-zirconate-titanate ceramics were studied using the constant current driving method. It was found that resonant frequency and mechanical Q markedly decreased with increasing vibration level, accompanying heat generation. The heat generation was assumed to be caused by vibration loss. The vibration loss was reduced by doping Fe atoms to the ceramics. On the contrary, the vibration loss was increased by doping Nb atoms.
