| 英文摘要: |
| The radial vibration of a thin piezoelectric ceramic ring polarized in the thickness direction is studied. Its electro-mechanical equivalent circuit is derived, the resonance and anti-resonance frequency equations are obtained, and the relationship between the resonance and anti-resonance frequencies with the material parameters and the geometrical dimensions is analyzed. |
