摘要

研究了用声波干涉仪测定不同声阻抗液体中声波的速度和衰减的理论和实验特点。首次表明，指示阻抗决定了同一收发对最大和最小传输系数S12的共振值与传输系数与换能器之间距离的依赖关系。已经开发了一种方法，用于确定液体的波衰减，而不受与换能器部分声功率损失相关的“表观”衰减的影响。

Determination of the Acoustic Wave Velocity and Attenuation in Liquids with Different Acoustic Impedances Using an Acoustic Interferometer

Theoretical and experimental features of using an acoustic interferometer for determining the velocity and attenuation of an acoustic wave in liquids with different acoustic impedances are studied. It is shown for the first time that the indicated impedance determines the ratio of the resonance values of the maximum and minimum transmission coefficient S₁₂ for the same transmitter–receiver pair on the dependence of the transmission coefficient on the distance between the transducers. A methodology has been developed for determining the wave attenuation of a liquid free from the influence of “apparent” attenuation associated with the loss of part of the acoustic power to the transducers.
