%X Hawking radiation from a dynamical Kerr black hole is investigated using a new tortoise coordinate and the improved Damour-Ruffini method. The local temperature changing with time and latitude angle and the Hawking radiation with quasi-blackbody spectrum are obtained. The present results are different from the existing results obtained by using usual tortoise coordinate. There exists a certain problem in dimension for the usual tortoise coordinate and the present results may be more reasonable.
