摘　　要：在考虑黑洞视界与宇宙视界具有关联性的基础上,证明de Sitter时空的热力学熵为黑洞视界热力学熵与宇宙视界热力学熵之和.给出了考虑两视界具有关联性后的de Sitter时空的热力学特性.研究表明,de Sitter时空的能量上限为纯de Sitter时空能量,deSitter时空的热容量是负的,de Sitter时空一般是量子力学不稳定的.Considering the fact that there is a correlation between the black hole horizon and cosmological horizon,we show that the thermodynamic entropy of de Sitter spacetime is the sum of thermodynamic entropies of the black hole horizon and cosmological horizon.The thermodynamic properties of de Sitter spacetime are also derived.It is shown that the upper limit energy of de Sitter spacetime is equal to the energy of pure de Sitter spacetime,The thermal capacity of de Sitter spacetime is negative,so de Sitter spacetime is mechanically unstable.
