The shear layer self-sustained oscillation on the opening of the cavity,the sound standing wave oscillation in the cavity and the vibration of the shell(wall of cavity) are induced simultaneously by a f low.
对腔口流体自持振荡和腔内声振荡的压力及壳的振动加速度作了测量和谱分析，并对三者之间的相互影响进行了综合研究。
The frequency of fluid dynamic self-sustained oscillation of a cavity is related to the length offlange of cavity.
腔口流体动力自持振荡的频率和导流板的长度有一定关系。
