| 摘 要： | 采用薄膜brick-wall模型．运用WKB近似，计算了在视界附近局部热平衡下缓变动态球对称荷电黑洞标量场的熵，结果表明，通过适当选取截断因子，仍可得出黑洞的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 scalar quantity field in the non-stationary and slowly changing spherically symmetric black hole with charge is calculated under local thermal balance. The result showed that the entropy of the R-N black hole is still proportional to its surface area if proper cut-off factors are chosen. |
