摘要
本文对电厂薄穿孔板的吸声结构做了定性分析,利用正弦和余弦的变化规律分析了吸声系数的变化关系,并且给出了多腔体结构吸声效果优于单腔体吸声结构。
In this paper,the sound absorption structure of thin perforated plate in power plant is analyzed qualitatively,and the change of the sound absorption coefficient is analysed by the variation rule of sine and cosine,and the sound absorbing effect of the multi cavity structure is better than that of the single cavity body.
