| 摘 要： | 2000年,Parikh和Wilczek给出了一个把霍金辐射看成是一个隧穿过程来解释信息守恒和霍金辐射是符合幺正性的。使用隧穿方法计算了Schwarzschild-de sitter黑洞的熵修正。讨论了Schwarzschild-de sitter黑洞的遗迹存在的可能性,并分析了宇宙常数对辐射带出的熵的影响。使用修正的Stefan-Boltzmann定律讨论了Schwarzschild黑洞和Schwarzschild-de sitter黑洞的蒸发率和遗迹问题。

| Abstract: | In 2000,Parikh and Wilczek treat Hawking radiation as a tunneling process to explain how information is conserved and Hawking radiation is a unitary process.In this letter,we calculate the entropy correction of Schwarzschild-de sitter black hole by using the tunneling formulism.The existence of remnant of Schwarzschild-de sitter black hole is proved,and we analyze the influence of cosmological constant ∧ to the entropy carried out by radiation.By using Stefan-Boltzmann Law,we discuss Schwarzschild black hole and Schwarzschild-de Sitter black hole′s evaporation rate and remnant. |
