Özet:

 

In this paper, by using quantum statistical methods, we  directly obtain the partition function of Bose field and Fermi field  on the background of the axisymmetrical Sen black hole.  The  difficult-to-solve wave equation is avoided.  Then via the improved  brick-wall method and membrane model, we calculate the entropy of Bose  field and Fermi field of the black hole.  We find that the entropy of  the black hole is proportional to the area of the horizon.  In our  results, we do not encounter the left out term nor the divergent  logarithmic term that appears in the original brick-wall method.  The  question that arose in the brick-wall method of whether the entropy of  the scalar or Dirac fields outside the event horizon is the entropy of  the black hole does not arise in the present method.  The influence of  spinning degeneracy of particles on entropy of the black hole is also  given.  We provide a way to study various complicated black holes.
