摘要
从热弹光声的基本方程出发 ,考虑热扩散效应、光穿透效应、电致伸缩效应 ,对液体中激光激励的声源进行了研究 .在一维情况下 ,通过解热扩散方程和波动方程 ,得出了位移的一般表达式 .讨论了热扩散效应、光穿透效应、电致伸缩效应对声波振幅的影响 .
The sound source which is generated by laser in liquids is studied theoretically on the basis of the thermoplastic equation which includes thermal diffusion effect, optical penetration effect and electrostriction effect. In one dimensional model, the general expression of wave displacement is obtained by solving the thermal diffusion equation and wave equation, which the influence of the thermal diffusion effect and the optical penetration effect on the wave displacement amplitude is analyzed.
