摘　　要：利用Ham liton-Jacobi方法,考虑自引力作用及能量和电荷守恒研究了球形磁单极荷电黑洞的隧穿辐射特性,得到的隧穿辐射谱不再是纯热谱,其隧穿几率与Hawking熵有关,所得到结果满足幺正性原理且对Hawking辐射进行了修正.Applying Hamliton-Jacobi method, the tunneling characteristic of the charged black hole with a global monopole is investigated by taking the self-gravitational interaction as well as the energy conserva- tion and charge conservation into account. The radiation spectrum deviates from the purely thermal one and the tunneling probability is related to the change of Bekenstein-Hawking entropy. The result satisfies an underlying unitary theory and gives a correction to the Hawking radiation.
