摘　　要：本文进一步完善了垂直场激励下压电板的谐振频率方程，并详细分析了耦合模的压电调频关系。进而提出了适用于垂直场或平行场激励下压电板的统一谐振频率方程。最后从物理上讨论了压电棒条与压电板振动的一致性及垂直场或平行场激励的本质上的内部联系。in present paper the resonant frequency equation for the thickness vibrations of the piezryelectric plate excited by perpendicular field has been more developed. The relations of the piezoelectricallytunable frequency of the coupling modes were analysed in detail. And then the universal resonantfrequency equation applied to the piezoelectric plate excited by a perpendicular or a parallel field isproposed. Finally, the consistance of vibrations for piezoelectric bar (or strip) and piezoelectric plate,and the internal relation excited by the perpendicular or the parallel fieldsare discussed physically.
