【Abstract】 Based on the polarized manner of a cylindrical piezoelectric ceramic transducer, the primary parameters of transducer are calculated and analyzed in the condition of radial polarization and tangent polarization. The results show that the mechanical resonance frequency, mechanical-electrical transition coefficient, static capacitance, receiving sensitive degree, etc depend on the polarized manner.更多还原
