摘　　要：分流气体对冲原理是利用声波反相抵消,来降低排气噪声中起主导地位的低频成份;利用气流对冲流速降低,从而减小气流再生噪声的原理,降低其他频带下的噪声。我对基于此原理的分流气体对冲排气消声器研究及现状进行了综述性的介绍,大致按时间顺序,分别对每位研究人员的研究方向、方法及研究成果进行了系统阐述。本文旨在汇总关于分流气体对冲原理所有文献,总结其成果、方法与不足,便于读者对此原理所做消声器有所认识,为未来的研究及应用提供方向和方法。The principle of split-stream rushing is to use sonic inverting offset to reduce the dominant low frequency part of exhaust noise;The air flow hedging speed is reduced to reduce the principle of airflow regeneration noise and reduce the noise under other frequency bands.I have made an overview of the research and current situation of split-stream rushing exhaust muffler based on this principle,and systematically expounded their research direction,method and research results in chronological order,in the unit of each researcher.The purpose of this paper is to summarize all the literature on the principle of split-stream rushing,summarize its results,methods and shortcomings,facilitate the reader's understanding of this principle of silencer,and provide direction and method for future research and application.
