基于对各阶简正波衰减量数值计算结果和简正波在管中分布的分析，提出一种按声功率优化分隔片相对半径 Ｒ 的方法。用这种方法得到的相对半径优化值与所得充水管道声分隔片结构的实验结果相符
Based on the numerical results of the simplified normal wave attenuation and the analysis of the distribution of the simple wave in the pipe, a method of optimizing the relative radius R of the divider by sound power is proposed. The relative radius optimization values obtained in this way are in good agreement with the experimental results of the resulting acoustic separator structure of the water-filled pipe
