| 摘 要： | 本从考虑损耗时压电振子的阻抗（或导纳）议程出发,详细分析了材料固有损耗对压电振子的频率特性及参数测量的影响。分析结果表明：谐振（或反谐振）频率与理想无损时的相应值的偏差随损耗的增大而增大、随谐序的增大而减小。中还进一步分析了机械损耗对压电振子几种常用参数测量结果的影响。

| Abstract: | In this paper, the influence of the intrinsic material losses on the resonance and parameters measurement of lossy piezoelectric resonators, based on the impedance (or admittance) equation, is analyzed. The results show that the discrepancy of resonance frequencies, between lossy resonator and corresponding lossless (ideal) resonator, is increased as the losses are increased and the harmonic number is decreased. The errors in measurement, related to the frequently used IEEE standard (or National Standard of China) method, is analyzed. |
