摘要
为使马大猷教授提出的关于微穿孔板吸声结构和吸声体的精确理论能够在生产实践中得到迅速而广泛的应用，本文进行了这方面的计算机辅助设计，并对其中的某些问题，如结构参数与吸声特性之间的相互影响及高声强环境下微穿孔极吸声体的设计特点等，进行了较为深入的分析和探讨．
In order to make Prof. Maa's accurate theory be applied in practice as soonas possible, in this paper, the computer aided design of miicroperforated -panel sbaorber based on the acctuate theory is made. In addition, some problems, therelation between the structural parameters and the properties of sound absorption, andthe design characteristics of microperforated -panel absorber at high sound intensity etc.,are discussed.
