【摘要】：黑洞物理学是一门集量子力学、广义相对论和天体物理等多学科的交叉理论，它在现代物理学中占据着非常重要的位置。黑洞的时空扰动与黑洞的基本参数的确定和黑洞的稳定性等问题有关，因此，一直以来受到广大物理学者的青睐。众所周知，似正规模仅由黑洞背景时空的参数决定，，与外场的初始扰动无关，因而它被认为是探测黑洞存在的直接证据。一旦引力波被探测到，那么，对黑洞似正规模的理论研究将为其提供重要的理论基础。本论文主要研究的是Quintessence物质包围的整体单极子黑洞的似正规模。本文共分为四大部分，前两个部分是对黑洞的起源与天文观测、黑洞的热力学性质、霍金辐射和黑洞的分类进行介绍；第三部分是对黑洞似正规模的定义、研究意义以及计算似正规模的方法（单值法、三阶WKB近似法、P-T势近似法以及有限差分法）作以介绍；在第四部分中首先介绍了Quintessence物质包围的整体单极子黑洞的度规；接着利用三阶WKB近似的方法计算了Quintessence物质包围的整体单极子黑洞在电磁扰动下的似正规模，并详细讨论了似正规模频率与各种参数之间的变化关系，这也是本论文的核心部分。最后是对本论文进行的总结。
[Abstract]:Black hole physics is a multidisciplinary theory of quantum mechanics, general relativity and astrophysics. It occupies a very important position in modern physics. The space-time perturbation of black hole is related to the determination of basic parameters of black hole and the stability of black hole. The quasi-positive scale is determined only by the parameters of the black hole's background spacetime and is independent of the initial disturbance of the external field, so it is considered as direct evidence to detect the existence of the black hole. Once the gravitational wave is detected, then, The theoretical study of black hole size will provide an important theoretical basis for black hole. In this paper, we mainly study the quasi-positive scale of monopole black hole surrounded by Quintessence matter. This paper is divided into four parts. The first two parts are about the origin and astronomical observation of black hole, and the thermodynamic properties of black hole. Hawking radiation and the classification of black holes are introduced in the third part, the definition of the size of the black hole, the significance of the research and the methods of calculating the size of the black hole (single value method, third order WKB approximation method, P-T potential approximation method and finite difference method) are introduced. In the fourth part, we first introduce the metric of the global monopole black hole surrounded by Quintessence matter, and then calculate the quasi-positive size of the global monopole black hole surrounded by Quintessence matter under electromagnetic disturbance by using the third-order WKB approximation method. The relationship between the frequency of quasi-positive scale and various parameters is discussed in detail, which is also the core part of this paper. Finally, the conclusion of this paper is given.
