摘　　要：用量子隧穿法研究Garfinkle-Horowitz-Stromingen dilaton黑洞的Hawking辐射,得到了静止质量为零和不为零的两类粒子穿过黑洞事件视界的出射率,发现粒子的量子隧穿辐射谱与黑洞的Bekenstein-Hawking熵变有关,辐射谱不再是严格的纯热谱.The quantum tunneling framework was adopted to investigate the Hawking radiation of Garfinkle- Horowitz-Stromingen dilaton black hole. The emission rate which mass-less and massive particles tunnel across the event horizon of the Garfinkle-Horowitz-Stromingen dilaton black hole was calculated, and a conclusion was made that the emission rate is related with the change of Bekenstein-Hawking entropy and the spectrum of radiation is not precisely thermal.
