Abstract:

Using brick wall method, the authors calculate the free energy and entropy o f the scalar  field on the background of non asympotic flat torus like black hole under the  sphere coordinates. The results show that the entropy not only is related to th e area of an outer horizon but also is the function of a inner horizon. Furtherm ore, the entropy expressed by inner and outer horizon will approach zero when th e radiation temperature of the black hole approaches zero. It satisfies the Nern st theorem. It can be taken as Planck absolute entropy.

Key words:  Brick wall method;Black hole entropy;Nernst theorem
