摘要
本文建立了热弹性流体介质中的波方程,指出了该介质中可能传播的两类波,并建立了热弹性P波的概念和基本特征。此外,本文还研究了热弹性波在液体—固体界面上的反射问题,给出了反射系数、透射系数的表达式以及反射热弹性P波、透射热弹性P波和透射SV型S波的基本特征。
In this paper,we established an equation of thermoelastic wave equation in thermal elastic fluid medium.It is pointed out that two kinds of waves can propagate in the medium possibly.The basic concept and characteristics of the thermoelastic P wave have been established.The reflection problem of thermoelastic waves in a liquid-solid interface has been studied.In addition,the reflection coefficient,the expression of the transmission coefficient,the character of reflective thermal elastic P wave and the type of SVS wave have also been given.
