This model considers the flow of energy between two regions around the black hole : an inner region that is close to the so--called event horizen (the boundary beyond which even light cannot escape ), and an outer region that includes the black hole's fuel source-- the young stars--extending up to a million times father out .
此模型分析围绕在黑洞周边的两个区域间的能量流:内部的区域接近于视界(一个理论上的边界,超过此边界甚至光都无法逃脱黑洞的吞噬),外部区域包括黑洞的燃料源——年青的恒星——并继续扩展数百万倍。

In Chapter 2, we study exact solutions of the separated parts of Klein-Gordon field equation on some stationary and axisymmetry black hole backgrounds. We demonstrate that the radial and angular parts of a massive scalar field equation in the Kerr-Newman and Kerr-Sen black hole space-times satisfies the generalized spheroidal wave equation which is, in fact, a confluent Heun equation.
在第二章中我们研究了稳态轴对称黑洞背景几何中Klein-Gordon场方程分离变量部分的精确解,表明了Kerr-Newman黑洞及Kerr-Sen黑洞中有质量复标量场方程的径向部分和角向部分均满足广义椭球波方程,而后者实际上就是合流的Heun方程。

In third chapter, We extend Horowitz and Maldacena's proposal about black hole final state to Dirac fields and find that if annihilation of the infalling positrons and the collapsed electrons inside the horizon is considered, then the nonlinear evolution of collapsing quantum state will be avoided.
在第三章中,我们把Horowitz和Maldacena关于黑洞终态的假设推广到了Dirac场并发现如果考虑黑洞蒸发过程中落进视界的负能粒子同黑洞物质之间的湮灭,那么出射态的非线性演化可以避免。

Light from stars directly behind the hole is swallowed by the horizon, while light from other stars is merely bent by the black hole's gravity, forming a warped image around the hole.
黑洞后面恒星释放的光被这一无尽边界所吞噬,而来自其他恒星的光则仅仅被黑洞印力作用所弯曲,在黑洞周围形成了一个变形的图像。

For the gas of 2D dilaton black holes,there existsa critical temperature.
我们推广了他们的研究至二维dilaton黑洞和2+1维黑洞情况,发现不仅微正则系综而且正则系综均可以描述这两个体系,对于二维dilaton黑洞体系还存在一个极限温度。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.
