摘要
运动的流体可以对声音产生作用，其方式与广义相对论中弯曲时空影响光线轨迹的方式相同。由此，可以通过一个有效度规来描述这些声波的传播，在该度规下声波将遵循零测地线。本论文对这些研究进行了综述，重点介绍了一个使用声学系统类比施瓦西黑洞的模型，并展示了其在霍金理论研究中的优势与局限性。A fluid in movement can act on the sound the same way that curved space-time can influence on light trajectory in the general relativity. So, one can describe the propagation these sound waves through an effective metric, under which they will follow null geodesics. This thesis makes a review of these studies focusing in an analogy to Schwarzschild black hole using an acoustic system, showing its advantages and limitations when applied in the study of Hawking's theory.
