我们描述了振动对有限体积流体的影响，这种流体由于其可压缩性而呈密度分层。我们证明了内部重力声波可以被振动参数化失稳。由此产生的不稳定性类似于表面波的经典法拉第不稳定性，尽管被流体的可压缩性所修正。在气液临界点附近进行实验观察是可能的。
We describe the effect of vibration on a confined volume of fluid which is density stratified due to its compressibility. We show that internal gravity-acoustic waves can be parametrically destabilized by the vibration. The resulting instability is similar to the classic Faraday instability of surface waves, albeit modified by the compressible nature of the fluid. It may be possible to observe experimentally near a gas–liquid critical point.
