在不同的锯切工艺参数和锯片结构下，测量了噪声值、噪声功率、噪声电压、振动功率和振动幅值，并对其进行频谱分析。

Noise value, noise power, noise voltage, vibration power and amplitude vibration were measured under different cutting parameters of technology and frequency spectrum analysis was also made.

随着流速的增加，结构的法向均方速度和辐射声功率均增大，但流速对结构辐射声功率的影响远大于对结构速度均方值的影响；

The effects of flow speed increase the mean square velocity and radiated power, the effect on radiated power is more obvious than on velocity.
