利用brick-wall方法计算了Schwarzschild黑洞背景下Dirac场的自由能和熵,得出了Dirac场的熵与黑洞视界面积成正比的结论,并进一步指出了Schwarzschild黑洞背景下Dirac场的熵为相应Klein-Gordon场的熵的7/2倍-By using of the brick-wall method,we calculate the free energy and the entropy of Dirac spinor field in Schwarzschild black hole-It shows that the entropy of Dirac field is proportional to the area of black hole horizon and the entropy of Dirac field is 7/2 times that of Klein-Gordon field-
