摘　　要：考虑到量子引力效应,对五维史瓦西黑洞时空中费米子的隧穿行为进行了研究.其研究结果表明,黑洞温度不仅由黑洞本身决定,同时,也受费米子的能量、质量以及额外维影响.量子引力修正减缓温度的增加,这将导致残余物质的存在.In this paper , taking into account effects of quantum gravity , we investigate fermions′tunne-ling behavior in a 5-dimeional Schwarzschild black hole .The result shows that the Hawking temperature is not only determined by the black hole , but also affected by the mass and energy of the emitted fermion and the effect of the extra dimension .Quantum gravity correction slows down the increase of the tempera-ture, which leads to the remnant in the evaporation .

关 键 词：量子引力效应 费米隧穿 额外维
