摘　　要：根据Lorentz-breaking理论对弦量场作用量进行修正并应用变分原理得到了高维Schwarzschild-de Sitter黑洞时空中的费米子动力学方程。通过对此动力学方程的研究得到了高维Schwarzschild-de Sitter黑洞事件视界处和宇宙视界处的量子隧穿率的修正形式,从而研究了此黑洞事件视界处和宇宙视界处的修正形式的Hawking温度和Bekenstein-Hawking熵的新的表达式。在得到研究结果的基础之上,文中最后还对研究方法和结论进行了讨论。The action of the string field is modified in accordance with Lorentz-breaking theory,and the variational principle is applied to obtain Fermions dynamics equation in the spacetime of high-dimensional Schwarzschild-de Sitter black hole.The modification form of quantum tunneling rate at the event horizon and cosmic horizon of high-dimensional Schwarzschild-de Sitter black hole are obtained through the study of this dynamics equation.Thus,the new expressions of Hawking temperature and Bekenstein-Hawking entropy at the event horizon and cosmic horizon of this black hole are studied.On the basis of the research results,the last part of the paper conducts an in-depth discussion about the research methods and the series of conclusions drawn.
