Abstract
The Hawking radiation of Dirac particles in a charged Vaidya-de Sitter blac k hole is investigated by using the method of generalized tortoise coordina te transformation. It is shown that the Hawking radiation of Dirac particle s does not exist for P-2, Q(1) components, but for P-2, Q(1) components it does. Both the location and the temperature of the event horizon change wit h time. The thermal radiation spectrum of Dirac particles is the same as th at of Klein-Gordon particles.
