| 摘 要： | 采用薄膜brick-wall模型,运用WKB近似,计算了缓变动态Reissner-Nordström黑洞的标量场的熵.结果表明,通过适当选取截断因子,仍可得出黑洞熵与视界面积成正比的结论.

| Abstract: | Using the thin film brick-wall model and WKB approximation,the entropy of the scalar quanti-ty field in the non-stationary and slowly changing Reissner-Nordström(R-N)black hole is calculated.The re-sult shows that the entropy of the R-N black hole is still proportional to its surface area if we choose proper cut-off. |

| Keywords: | slowly changing thin brick-wall model entropy of black hole |
