实验研究了矩形空腔在外部高速气流作用下诱导的空腔内流动振荡问题，以及从空腔前缘加入纯音声激励以抑制空腔内流动振荡的技术。
The flow induced oscillation in a cavity exposed to external high speed flow and its suppression by means of sound excitation at the leading edge of the cavity are experimentally studied.
实验发现，在一定的气流速度和空腔几何尺寸下，空腔内流动会出现强烈的自持振荡。
In the experiment it is found that at a certain external flow velocity and cavity size a strongly self sustained flow oscillation in the cavity would appear.
