We present observational confirmation of Hawking's black-hole area theorem based on data from GW150914, finding agreement with the prediction with 97% (95%) probability when we model the ringdown including (excluding) overtones of the quadrupolar mode. We obtain this result from a new time-domain analysis of the pre- and postmerger data. We also confirm that the inspiral and ringdown portions of the signal are consistent with the same remnant mass and spin, in agreement with general relativity.
我们基于GW150914的数据给出了霍金黑洞面积定理的观测验证，当我们在建模衰减过程时纳入（排除）四极模式的泛音，发现与预测结果相符的概率为97%（95%）。我们通过对合并前和合并后数据进行新的时域分析得到了这一结果。我们还证实，信号的旋进和衰减部分与相同的残余质量和自旋一致，这与广义相对论相符。
