摘　　要：介绍了单节扩张室消声器的消声特性及缺陷,提出了用内插管形式来改善单节扩张室消声器的消声性能,并从实验上分析并比较了这两种扩张室水消声器的消声性能,实验表明内插管扩张室水消声器比单节扩张室消声器具有更好的消声效果。The characters and the shortcoming of one-section expanded muffler are introduced.The internal spile is used to improve of the performance of noise elimination.At the same time, the performance of noise elimination is analyzed and compared based on experiment between the two kinds of muffler.The experiment shows that the water expanded muffler with internal spile takes better effect on flow-noise than the one-section expanded muffler.
