| 摘 要： | 分析了压电材料中的损耗现象，并用复数表示有损压电振子的各种参数。文章从压电振子的阻抗（或导纳）方程出发，详细分析了纵效应振动及横效应振动模式振子的谐振（或反谐振）频率、频率偏移量与损耗大小、机电耦合系数大小的关系。

| Abstract: | The phenomena o f loss in the piezoelectric materials is analyzed, and many parameters of lossy piezoelectric resonator can be character ized by complex parameters. The equivale nt circuits of lossy resonators can be c haracteried bycomplex parameters. Based the impedance(or admittance)equation,the connection of the resonance(or anti-res onance)frequency,the frequency displacem ent with the loss magnitude,the size of the piezoelectric coupling factor are an alyzed in detail. |
