论文摘要
在本文中，我们研究了以辐射为主时代和以物质为主时代的原始黑洞的蒸发和积聚的过程。该主题非常重要，因为通常这两个过程被认为是彼此独立的。换句话说，以前的作品以这种方式认为它们没有直接影响，因此，它们对原始黑洞质量的影响是分别计算的。本文的计算表明，假设这两个过程彼此独立，将导致错误的结果，仅在一定范围内给出正确的答案。实际上，通常，考虑原始黑洞的事件范围的静态状态并执行与其蒸发相关的计算是一个错误，而原始黑洞的半径则由于积聚而不断变化。此外，我们已经表明，考虑到某些质量的动态事件范围，并且在某些时候可能导致霍金蒸发过程的关闭。这项研究比我们以前的研究更准确和详细。这些计算很好地表明了从形成时间到物质主导时代结束的原始黑洞的质量演变，这两个主要过程都涉及黑洞，蒸发和积聚。
In this paper, we have investigated the processes of evaporation and accretion of primordial black holes during the radiation-dominated era and the matter-dominated era. This subject is very important since usually these two processes are considered independent of each other. In other words, previous works consider them in such a way that they do not have a direct effect on each other, and as a result, their effects on the mass of primordial black holes are calculated separately. The calculations of this paper indicate that assuming these two processes independently of each other will lead to wrong results that only give correct answers within certain limits. In fact, in general, it is a mistake to consider the static state for the event horizon of primordial black holes and perform calculations related to their evaporation, while the radius of primordial black holes is constantly changing due to accretion. In addition, we have shown that considering the dynamic event horizon in some masses and in some times can lead to the shutdown of the Hawking evaporation process. This study is much more accurate and detailed than our previous study. These calculations show well the mass evolution of primordial black holes from the time of formation to the end of the matter-dominated era, taking into account both the main processes governing black holes, evaporation and accretion.
