Mirror lock-up (MLU) is a feature available in some SLR cameras which aims to minimize camera shake induced by mirror-slap (which produces the characteristic snapping sound of SLR cameras).

有些单反相机具有反光镜锁定(MLU)功能，可以减小镜面翻转造成的相机抖动(这也是单反相机经典“喀嚓声”的来源)。

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。
