声学黑洞简介

Introduction to acoustic black hole

介绍了一种引力黑洞的类比模型———声黑洞.从几何声学和物理声学两方面对其类比原理进行了分析,介绍了声黑洞的定义及其结构参数.回顾了在声黑洞的研究历程中所取得的重要进展,分析指出声黑洞的研究目前存在的理论和实验上的困难,并对未来的研究进行了展望.

An analogue model for gravity black hole, the acoustic black hole, is introduced. The analoguemechanism is shown from the aspects of both geometrical acoustics and physical acoustics. The definition of acoustic black hole and its structure are introduced. The important developments in history of the study on acoustic black hole are reviewed. The difficulties in both theory and experiment of today＇ s research on acoustic black hole are analyzed. We also give an outlook for the further research on the acoustic black hole.
