Poletti和Wiltshire已经证明，除了一个纯宇宙学常数外，在de Sitter或反de Sitter宇宙背景中的介子黑洞的解在一个Liouville型介子势存在时不存在。本文在de Sitter宇宙或反de Sitter宇宙背景下，利用三个Liouville型的玻色子势的组合，得到了玻色子黑洞解.
Poletti and Wiltshire have shown that, with the exception of a pure cosmological constant, the solution of a dilaton black hole in the background of de Sitter or anti-de Sitter universe, does not exist in the presence of one Liouville-type dilaton potential. In this work we obtain the dilaton black-hole solutions in the background of the de Sitter or anti-de Sitter universe, with the combination of three Liouville-type dilaton potentials.
