By the theory of flow instability and receptivity, the rule of using this phenomenon to improve turbomachinery performance can be found. 利用流动稳定性及感受性理论来指导对这一问题的研究，能够找到利用这一现象提升叶轮机性能的规律。
For liquid film flow under the effect of gas flow, the hydrodynamics and flow stabilities of liquid film are obviously influenced by the interfacial shear stress. 当气液界面有同向或反向气体掠过时，气液界面存在切应力，必然影响到液膜的水动力学特性和流动稳定性特征。
