| 摘 要： | 本文基于热弹性理论推导了凝聚态介质中光声效应的基本方程。在某些有实际意义的条件下给出了光声信号的简化表达式。对采用脉冲光(或强度调制光)作为激励源的情况下,得出了一般解,并讨论了某些可以忽略热扩散的特殊情况。 |

| Abstract: | Based on thermoelastic theory, this paper derives equations of photoacoustic effect in condensed matter. Under some conditions having practical function, simplified equations of photoacoustic signal are put forward. A general solution is given when pulsed laser beam (or modulated light) is used as the activation source. Some special cases in which thermal diffusion is negligible are also discussed. |
