Waveguide Systems for Flexural Vibrationson of forced harmonic elastic vibrations from their source to a load in a steady-state resonance regime. This implies that the possible vibration waveforms of interest in these waveguides are determined by the conditions under which they are driven by the harmonic force at the resonance frequency angustation 发表于 2025-3-28 22:22:19

Calibration of Ultrasonic Receiversitivity, which is defined as the ratio of the emf developed by the ultrasonic receiver at a certain point of the ultrasonic field to the ultrasonic pressure that would exist at the same point of the field in the absence of the receiver.exclamation 发表于 2025-3-29 10:42:10

Matchingde system. Two problems are solved in this case: (a) compensation of the reactive component X. of the input load impedance; and, (b) reduction of the resistive (active) component R. to the required optimum value.Immunization 发表于 2025-3-29 18:26:30
Transmission into Liquid Mediaradiating surface upsets the homogeneity of the vibrations, i.e., in addition to the longitudinal modes of the radiator, which form a plane wave with all points of the radiating surface vibrating in phase and with the same amplitude, there also occur complex flexural modes.事物的方面 发表于 2025-3-29 21:17:26
