摘要
本文运用Newman-Penrose方法推出de Sitter度规下的自旋系数，讨论了经典场的渐近特性，给出平凡解。并得到de Sitter空间中场方程一般可化为Liouville方程。
In this paper, We use Newman-penrose method to derive spin coefficient in de sitter gauge, discuss the asymptotic trait of classical fields to get trivial solutions. We also conclude that the field equations in de sitter space are generally changed into liouville equations.
