我们使用基于量子WKB方法的隧道形式计算了史瓦西黑洞的霍金温度和贝肯斯坦-霍金熵的修正。这些结果与轨迹异常有关，并被证明与霍金基于zeta函数正则化的路径积分的原始计算推断的结果等效。最后，利用修正后的温度和周期性参数，我们还发现了原始史瓦西度规的修正，它捕获了量子修正的影响。
We compute the corrections, using the tunneling formalism based on a quantum WKB approach, to the Hawking temperature and Bekenstein–Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be equivalent to findings inferred from Hawking's original calculation based on path integrals using zeta function regularization. Finally, exploiting the corrected temperature and periodicity arguments we also find the modification to the original Schwarzschild metric which captures the effect of quantum corrections.
