摘要

本文用声学近似方法研究了波信号在液体中通过气-汽泡屏时的动力学，并考虑了界面处的传热和传质。采用数值计算和快速傅立叶变换方法获得了压力脉冲的波形，并研究了含汽-气泡液体状态的各种参数对声波在筛网中的反射和透射的影响。

TRANSMISSION OF PULSED SIGNALS THROUGH A LAYER WITH VAPOR-GAS BUBBLES IN WATER

This paper describes a study of the dynamics of a wave signal passing through gas-vapor bubble screensin a liquid with account for heat and mass transfer at an interface in an acoustic approximation. Numerical calculations and the fast Fourier transform method are used to obtain wave patterns for pressure pulses and describe the influence of various parameters of the state of the liquid with vapor-gas bubbles on reflection and transmission of acoustic waves through the screen is studied.
