摘　　要：本文提出了一种二维黑洞热机模型,并研究了该热机的效率。发现其效率与黑洞辐射粒子前后的质量有关,此结果与以往文献所得出的结论一致。此外,还证明了黑洞辐射过程中最小半径的存在,并与先前的相关结论进行了比较和讨论。In this paper,a heat engine via a 2-dimensional black hole is defined and its efficiency is calculated.It is found to be related to black hole s masses before and after the particles emission.The result is consistent with the previous one derived from relevant literature.The existence of the minimum radius of black hole is also proved.A comparative study with the previous relevant results is presented in the paper as well.
