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.
正好适用于水动力噪声试验设备，其中背景噪声强，而且可以得到比较纯净的背景噪声作为参考噪声。
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.
该软件分析精度高、易操作，可给出流噪声强度随航速变化的规律和功率谱等指标。
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.
对于水动力噪声情况，感兴趣的频率厚度乘积相当低，这时零阶对称模式对噪声辐射起主要作用。
