评论：观察到金属氢的Wigner-Huntington跃迁
Comment on: Observation of the Wigner-Huntington transition to metallic hydrogen
摘要：
在最近发表的一篇文章[1]中，Ranga P. Dias & Isaac F. Silvera已经报道了金属氢的视觉证据，伴随着其在495 GPa压力和低温下的表征。我们在接受采访时对这一结论表示严重怀疑[2，3]。在下面的评论中，我们想根据我们和世界各地其他团体获得的支持我们怀疑论的实验证据，详细说明原因。我们在本文中发现了两个主要缺陷，如下所述：压力被大大高估;样品反射率的来源和反射率的分析可能受到严重质疑。
英文摘要：
In a recently published article [1], Ranga P. Dias & Isaac F. Silvera have reported the visual evidence of metallic hydrogen concomitantly with its characterization at a pressure of 495 GPa and low temperatures. We have expressed serious doubts of such a conclusion when interviewed to comment on this publication [2,3]. In the following comment, we would like to detail the reasons, based on experimental evidences obtained by us and by other groups worldwide that sustain our skepticism. We have identified two main flaws in this paper, as discussed in details below: the pressure is largely overestimated; the origin of the sample reflectivity and the analysis of the reflectance can be seriously questioned.
