摘要：
We calculate the free energy and the entropy of a scalar held in terms of the brick-wall method in the background of the Schwarzschild-de Sitter space-time. We obtain the entropy of a black hole and the cosmic entropy at nonasymptotic flat space. When the cutoff satisfies the proper condition, the entropy of a black hole is proportional to the area of a black hole horizon, and the cosmic entropy is proportional to the cosmic horizon area.
