摘要

We study the sound perturbation of a rotating acoustic black hole in the presence of a disclination.The radial part of the massless Klein-Gordon equation is written into a Heun form,and its analytical solution is obtained.These solutions have an explicit dependence on the parameter of the disclination.We obtain the exact Hawking-Unruh radiation spectrum.
