摘要
本文通过对圆锯空载时空气动力噪声的发声机理研究，探讨这类噪声（气动噪声）的主源及其辐射特征，最后提出低噪据片的改进型结构．
Based on noise analysis for an idling circular saw, the mechanism ofaerodynamic noise is investigated. In this way, the paper probes into the main soure ofthe circular saw aerodynamic noise as well as its radiation nature. Finally, an improvedcircular saw structure for lower noise is suggested.
