黑洞也是一种热力学系统，则对于黑洞通常的热力学定律也应该成立。基于此，研究了巴丁黑洞的热力学量及其热力学稳定性。结果表明巴丁黑洞的熵应该仍然是贝肯斯坦-霍金熵，但是巴丁黑洞的质量不再是该系统的内能。利用重新定义的巴丁黑洞内能，计算了热容量和热力学曲率，以此分析了巴丁黑洞的热力学稳定性和相变。

Black hole is a type of thermodynamic system, thus the usual thermodynamic laws should be established. On the basis of this belief, we study thermodynamics of Bardeen black hole. It is shown that the entropy of the black hole still obeys the Bekenstein-Hawking area law, however, the black hole mass M can no longer be considered as the internal energy of the black hole thermodynamic system. Using this redefined internal energy of regular black holes in the first law, we calculate the heat capacity and thermodynamic curvature to understand the stability of the Bardeen black holes.
