摘要

We derive the general form of Hawking temperature for Vaidya black hole in the tun-neling pictures. This type of black hole is regarded as the description of a more realistic one compared to static case such as Schwarzschild's solution. The black hole mass in Vaidya solution is time dependent and decreasing due to evaporation process. Clearly,the temperature would be time dependent as our ndings show. We use the semiclassical methods, namely radial null geodesic and complex paths methods. Both methods are found to give the same results. Then, we discuss the possible form of the corresponding entropy.
