【 摘 要 】

Novel method for identification of intrinsic vibration modes in piezoelectric crystals is introduced. This method is based on recently proposed theoretical model of piezoelectric resonance frequencies dependence on temperature. Calculation of crystal sample eigenmodes is based on Lagrange-Hamilton variation principle. Comparison of temperature dependencies of calculated resonance frequencies with measured ones reveals reliable method for identification of vast majority of the experimentally observed resonances. Influence of sample sizes variation on eigenmode frequencies is also considered.
