The effectiveness of sound intensity has been analysed and the basis for precision acousticmeasurement has been laid in this paper.
本文对声强测量的有效性作了较全面分析，为精确的声测量奠定了基础。

Then this article also introduces the acoustic the basic knowledge and theory on cavitation, and sums up the previous measurement methods of acoustic cavitation intensity.
接着本文还介绍了关于声空化的基本知识和理论，总结了前人的研究声空化强度的测量的方法。
