摘要
利用ｂｒｉｃｋｗａｌ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ＫｌｅｉｎＧｏｒｄｏｎ场的熵的７／２倍．
Abstract 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.
