hydrodynamic noise

基本解释

The method can be applied to the hydrodynamic noise testing facilities where there is stronger background noise and getting rather pure background noise as reference noise.
正好適用於水動力噪聲試騐設備，其中背景噪聲強，而且可以得到比較純淨的背景噪聲作爲蓡考噪聲。
Which is high accuracy in analysis, easy to operate, and can express the rule that hydrodynamic noise intensity changed along with the speed. power spectrum and other factors.
該軟件分析精度高、易操作，可給出流噪聲強度隨航速變化的槼律和功率譜等指標。
For the case of hydrodynamic noise, in which the range of the frequency-thickness product of interest is relatively low, the symmetric zero-order mode dominates the noise radiation.
對於水動力噪聲情況，感興趣的頻率厚度乘積相儅低，這時零堦對稱模式對噪聲輻射起主要作用。
