| Abstract: | The strictly thermal spectrum in dragging coordinate system and the tunneling radiation characteristics of stationary axisymmetry Kerr-Newman de Sitter black hole is studied. The result shows that the tunneling rates at the event and cosmological horizon are related to the change of Bekenstein-Hawking entropy and that the factual radiation spectrum is not strictly pure thermal. Thus an exact correction to the Hawking thermal spectrum is present. |
| Keywords: | Kerr-Newman de Sitter black hole tunneling rate energy conservation angular momentum conservation Bekenstein-Hawking entropy. |
