摘要：

We show that the unique invariant locally Minkowskian state of quantum fields in de Sitter space M has for an observer moving along with a killing vector field a temperature 1/2 pi root 1/R2 + \a\(2) where R is the radius of M and a his acceleration. States with another temperature cannot be locally Minkowskian all over M.
