摘　　要：讨论了在黑洞熵具有量子修正的情况下黑洞温度的修正,以及由此而引起的黑洞寿命的变化.研究发现,黑洞蒸发到普朗克质量时,温度降出现无限大,再减小质量时将出现负温,此时黑洞熵也将出现极小值.The temperature correction of the black hole is discussed with change of lifespan induced by the correction under the circumstance of the quantum entropy correction. It is found that, when the black hole mass evaporates to the level of Planck mass, the temperature emerge infinitely high. If keeping on evaporating, the temperature will become a negative, and the entropy will get to the minimum value at the same time.
