摘要
从热力学角度介绍了光声效应的产生机制,并设计出简单的实验装置,从实验上验证了理论的正确性,对光声谱学作了简单介绍．
This paper mainly discusses the productive mechanism of optic-acoustic effect by concerning with thermodynamics, and provides a simple experimental apparatus. The theory is testified to be authentic and together gives a brief introduction to Optical Acouspectrum in a way.
