利用量子引力中广义测不准原理导出的新的态密度方程，研究了介质黑洞的统计熵。当广义测不准原理中引入的λ取某一特定值时，我们发现介电黑洞统计熵的首项取Bekenstein-Hawking熵形式。此外，还得到了有限修正项。与原来的brick-wall模型相比，我们的计算没有发散，也不需要小质量近似。
Using the new equation of state density from the generalized uncertainty principle in quantum gravity, we study statistical entropy of a dielectric black hole. Whenλintroduced in the generalized uncertainty principle takes a specific value, we find that the leading term of the statistical entropy of the dielectric black hole takes the Bekenstein-Hawking entropy form. In addition a finite correction term is also obtained. Comparing with the original brick-wall model, in our calculation there is no divergence and the small mass approximation is also not needed.
