摘    要:根据Hawking热辐射理论和Parikh的半经典量子隧穿模型,作者选择了一种零标架对该Kerr黑洞Dirac 粒子热辐射的研究表明,其热辐射谱是纯热谱.对该Kerr黑洞量子隧穿辐射的研究结果却表明,在能量守恒和角动量守恒的条件下,此黑洞事件视界处粒子的隧穿率与Bekenstein-Hawking熵变有关,真实的辐射谱不再是严格的纯热谱,但满足量子力学中的么正性原理,这是对Hawking纯热谱的一种修正.

关 键 词:Kerr黑洞  Dirac方程  纯热谱  隧穿几率  Bekenstein-Hawking熵

Abstract:Applying Hawking's thermal radiation theory and Parikh s semi-classical quantum tunneling method,the authors choose a null tetrad to study the quantum thermal radiation of Dirac particles.The radiation spectrum is purely thermal.The study to the tunneling radition characteristics of the Kerr black hole,shows that the tunneling rate of the particle at the event horizon is related to the chang of Bekenstein-Hawking entropy when taking the energy conservation and angular momentum conservation into consideration,and that the radiation spectrum is not strictly purely thermal,but is consistent with the underlying unitary theory.This is a amendment to Hawking pure thermal spectrum.
Keywords:kerr black hole  dirac equation  pure thermal spectrum  bekenstein-Hawking entropy
