| 摘 要： | 介绍了黑洞理论和广义相对论中的几个重要疑难,涉及霍金辐射、信息佯谬、奇性定理和钟速同步,并给出了可能的解答。介绍了计算动态黑洞温度的方法,给出了由于不可逆性而导致霍金辐射过程中信息丢失的论证,还给出了类光测地线固有加速度发散的论证。指出了钟速同步与热力学第零定律的关系,以及奇性定理与热力学第三定律的关系。

| Abstract: | Some major puzzles in black hole theory and General Relativity, including Hawking radiation, information puzzle, singularity theorem and synchronization of clock rate, are presented. The possible answers are given. We introduce a method to calculate the temperature of a non-stationary black hole; the proof on the information loss during Hawing radiation due to the irreversibility of the process, and the proof on the proper acceleration being infinity for null geodesics. The relation between the synchronization of clock rate and the zeroth law of thermodynamics, and the relation between the singularity theorem and the third law of thermodynamics are pointed out. |
