摘　　要：We revisit Parikh-Wilczek tunneling through the de Sitter horizon and obtain the tunneling rate in Schwarzschildde Sitter space,which is non-thermal and closely related to the change of entropy.We discuss the thermodynamics of Schwarzschild-de Sitter space and show existence of correlation which can ensure conservation of the total entropy in the transition process of Schwarzschild-de Sitter space to de Sitter space.The correlation and the conserved entropy provide a way to explain the entropy in empty de Sitter space.
