Statistical entropy of Barriola-Vilenkin black hole
Barriola-Vilenkin黑洞的统计熵

The partition functions of bosonic and fermionic field in Barriola_Vilenkin black hole are directly derived by using the method of quantum statistics. Then the entropy of the Barriola_Vilenkin black hole is calculated by using the improved brick_wall method in the frame of membrane model.
