摘　　要：拓展Banerjee和Majhi研究黑洞Hawking辐射的方法,在保持时空中总能量、总电荷和总角动量守恒的条件下,利用新定义的Tortoise坐标变换研究带电旋转黑洞的Hawking辐射.在考虑辐射粒子对时空的反作用后,不但得到满足量子力学幺正性原理的黑洞辐射谱.而且在结果中显示,由带电旋转粒子引起的辐射谱中类似化学势的项,入射波与出射波的贡献是相等的.使人们对黑洞Hawking辐射的物理机理又有了一种新的理解.We extend the method that Banerjee and Majhi studied Hawking radiation.Under the condition that the total energy,total charge and total angular momentum of spacetime are conservative,we discuss Hawking radiation of the charged rotating particle by the new defined Tortoise coordinate transformation.Taking the radiation particle reaction to the spacetime into consideration,we obtain the black hole radiation spectrum that satisfies the unitary principle of quantum mechanics.And it is shown that the contribution from ingoing wave is equal to the one from outgoing wave in the radiation spectrum chemical potential term caused by the charged rotating particle.It makes people have a new understanding to physical mechanism of Hawking radiation of the black hole.
