摘要：
We calculate the free energy and entropy of the Dirac field in terms of the brick-wail method by faithfully following the definition of the Reissner-Nordstrom black hole. We obtain the conclusion that the entropy of the Dirac field is proportional to the area of the horizon of a black hole. Besides; we show that on the background of the Reissner-Nordstrom black hole the entropy of the Dirac field is 7/2 times as large as the entropy of the Klein-Gordon field.
