Abstract ： Absorbing charged rotating (ACR) metric in de Sitter space and related energy-momentum tensor are derived. The ACR metric is very simple in advanced time coordinates. The ACR metric involves 8 independent parameters which are divided into two classes: (1) the mass M, charge Q, angular momentum per unit mass a, and cosmological constant Λ ; (2)∂M/∂v, ∂2 M/∂v2 , ∂Q/∂v, and ∂2 Q/∂v2 . The non-stationary part of the energy-momentum tensor is positive definite everywhere.
