One of them is the sound standing wave resonance of fluid in cavity, the frequencies of which are invariable as velocity of flow is increasing.
经过分析，发现突出试验段壁上的流线型腔与突出的矩形腔在气流中被激振荡相似，存在着其频率与流速无关的腔中液体声共振谱峰；
Analytical solutions were obtained, and the formulae for resonance frequency, velocity distribution, amplitude ratio and node location derived.
我们获得了解析解，然后给出了共振频率、速度分布、振幅比和节点位置公式。
The harm of the secondary resonance could be improved by the measures such as using the acceleration detector core body, increasing the damp of velocity detector core body and so on.
采用加速度检波器芯体、增大速度检波器芯体阻尼等措施，可改善二次谐振的危害，经实际应用效果较好。
