hydrodynamic noise

基本解釋

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.
正好適用于水動力噪聲試驗(yàn)設(shè)備，其中背景噪聲強(qiáng)，而且可以得到比較純凈的背景噪聲作為參考噪聲。
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(qiáng)度隨航速變化的規(guī)律和功率譜等指標(biāo)。
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.
對于水動力噪聲情況，感興趣的頻率厚度乘積相當(dāng)?shù)停@時(shí)零階對稱模式對噪聲輻射起主要作用。
