文摘Using the thin film brick-wall model and WKB approximation,the entropy of the Dirac field in the non-stationary and slowly changing Reissner-Nordstrom(R-N)black hole is calculated.The result shows that the entropy of the R-N black hole is still proportional to its surface area if we choose proper cut-off.
