摘要：
Problems related to applying the concepts of resonance and antiresonance frequencies of a plate piezotransducer have been studied. The case of a plate unilaterally loaded on an aqueous medium has been researched. It has been shown that the concept of the antiresonance frequency determined with the use of an elastic modulus c33D can be applied only conditionally, still allowing one to calculate frequency characteristics for different values of a squared electromechanical-coupling coefficient. Notwithstanding the conditional nature of the term “antiresonance”, its practical use does not cause any difficulties.
