标题： Analogue of superradiance effect in acoustic black hole in the presence of disclination

摘要： 在本文中，我们研究了声学类似现象的可能性，如超辐射，即声音波在旋转声学黑洞的流体“漏斗浴缸”模型中从能层区域反射时被放大，存在位错的情况下，其幅度可以按缺陷角的值被放大或减少。 显示英文摘要

摘要： In this paper we invstigate the possibility of the acoustic analogue of a phenomenon like superradiance, that is, the amplification of a sound wave by reflection from the ergo-region of a rotating acoustic black hole in the fluid "draining bathtub" model in the presence of a desclination be amplified or reduced in agreement with the value of the deficit angle.
