摘要
Metric of accelerating,radiating Kerr-Newman de Sitter black holes is derived in this letter.The metric involves(7+10)independent parameters.The volume density of space-time,and the electromagnetic potential in accelerating,radiating cases are the same as in nonaccelerating,nonradiating cases.The space-time related to acceleration is not asymptotic Minkowski flat.So the energy momentum tensor is not positive definite.
