摘要：
In this paper, we first calculate the emission rate of the massive particles' de Sitter tunneling across the cosmological horizon of Schwarzschild-de Sitter black holes to the second order accuracy. Then, by assuming the emission process satisfies an underlying unitary theory, we have obtained the corrected entropy for cosmological horizon. Finally, a discussion about the de Sitter tunneling is presented.
