| 摘 要： | 从标量粒子满足的克莱因-高登方程出发,利用薄膜模型方法计算精质包围的Reissner—Nordstrom（R—N）黑洞的熵。薄膜模型的应用,克服了原始砖墙模型中的小质量近似和对数项忽略等不自然的操作。计算结果表明,该黑洞的熵是黑洞视界面积和宇宙视界面积之和的1／4。可见,精质包围的Reissner—Nordstrom黑...

| Abstract: | Based the Klein-Gordon equation of scalar field,the entropy of Reissner-Nordstrom black hole with quintessence is calculated by using the thin-film model method.This method avoids some drawbacks in the original brick-wall method such as the little mass approximation and neglecting logarithm term.It is found that the entropy of the black hole is 1/ 4 of the sum of the areas of the event horizon and cosmological horizon.So,the entropy of the system not only includes the contribution of the black hole horizon,... |
