中心黑洞体系球对称度规及熵的整体研究

A entire study of the spacetime metric and entropy of the system containing a blackhole

摘要: 研究了球对称黑洞及其周围物质组成的系统的熵.首先求出了球对称黑洞内外含宇宙项Λ的时空度规,在此基础上给出了黑洞外物质的熵及这一体系的总熵的计算公式并对两种特殊情况下的熵进行了讨论,所得结果在量级上与已知结果一致.

Abstract: This paper studies the entropy of the spherical symmetry system containing a blackholeFirst,the spacetime metric of this system with the nonzero cosmological constant was derived ,then the formulae of the entropy of the system was obtained.Finally,the entropies of two special systems with some conditions were discussed.The results obtained are consistent with the results in the literatures
