摘　　要：采用Ham ilton-Jacob i方法对动态Vaidya黑洞的Hawk ing隧穿辐射进行研究,结果表明该黑洞的辐射谱不是纯热谱,且出射粒子的隧穿率与Bekenste in-Hawk ing熵变有关.本文不仅提出了一种研究动态黑洞Hawk ing隧穿辐射的新方法,而且得出了有意义的结果.We have applied Hamilton-Jacobi method to study the Hawking radiation as tunneling from non-stationary Vaidya black hole. The result shows that the radiation spectrum isn＇t pure thermal and the tunneling rate is related to the change of Bekenstein-Hawking entropy. Thus a new method to study the Hawking radiation as tunneling from non-stationary black holes is presented and a meaningful result is gotten in the paper.
