论文摘要
在本文中，显示出与振荡气泡的相互作用，流体变得不均匀。流体的声学折射率的径向变化会产生带球体对称性的声透镜。当与气泡簇相关的透镜的焦距等于位置向量的长度时，气泡簇的行为就像哑孔。与气泡的性质不同，在有吸引力的内力的作用下通过压缩，簇可以缩小其半径成为哑孔。
In this paper, it is shown that in interaction with an oscillating bubbles cluster the fluid becomes inhomogeneous. The radial variation of the acoustic refractive index of the fluid generates an acoustic lens with spherical symmetry. When the focal length of the lens associated with the bubbles cluster is equal to the length of the position vector then the bubbles cluster behaves like a dumb hole. Unlike the properties of a bubble, the cluster, by compression under the action of attractive internal forces, can shrink its radius to become a dumb hole.
