Recently the discovery of room-temperature superconductivity was announced for a carbonaceous sulfur hydride (CSH) under high pressure. The evidence for superconductivity was based on resistance and magnetic susceptibility measurements. In the figures showing the susceptibility it was stated that "the background signal, determined from a non-superconducting CSH sample at 108~GPa, has been subtracted from the data". From a thorough data analysis we show that the data are incompatible with the notion that the susceptibility data are obtained from the "measured voltage" using a background correction. On the other hand the data {\it are} compatible with the reverse procedure, namely the "measured voltage" is obtained by adding a "background signal" containing noise to what was reported as the background-corrected susceptibility. For all 6 of the reported pressures our analysis leads to the conclusion that: (i) the reported background-corrected susceptibility data are pathological, (ii) they were not obtained by the method described in this paper nor by any one of the alternative 3 methods that were subsequently provided by the authors and (iii) the "measured voltage" data are not raw data.

在本文中，我们回应了最近由Hirsch和van der Marel在arXiv（3）上提出的对我们在CSH（1，2）上的工作的批评。我们指出，他们的非同行评议的批评（3）源于缺乏科学理解或未能适当分析原始数据。我们解释说，使用他们的“Unwrapped”方法是不适当的。(3)我们提出科学证据，证明他们的方法中使用的这种基本和根本的失败导致了参考文献（3）中提出的错误陈述。我们还注意到，在Hirsch和van der Marel在arXiv上发表他们的评论之前，Hirsch可以获得参考文献（1，2）的原始数据。(3)我们支持参考文献（1，2）的发现和结论，并继续致力于科学研究的完整性。

在最近的预印本[arXiv：1803.04118v2]陈和巴罗斯报告了有吸引力的哈伯德模型的平均场相互作用猝灭动力学的数值模拟，证实了我们早期的预测[Europhys. Lett. 85，20004（2008），arXiv：0805.2798]的自发爆发的空间不均匀性的后淬火状态与周期性振荡超导秩序。Chern和Barros将这种空间涨落的不稳定性归因于最终Hubbard耦合$U_f$的大幅度。我们指出，这种解释是不准确的，并讨论进一步的工作，数值验证的不稳定性和稳定状态的性质的机制。
