给出了室温下测量的液态水的准确高能X射线衍射数据。考虑了实验中系统误差和统计误差的来源，并讨论了数据一致性检查。结果表明，所得到的X射线对分布函数在实空间中是平滑变化的，并且在3-5ä区域没有出现小峰的迹象。我们的结果与Petkov等人最近在2012年《物理学杂志：康登斯》上报道的结果形成了鲜明对比。物质24 155102。
Accurate high energy x-ray diffraction data are presented on liquid water measured at room temperature. Sources of both systematic and statistical errors within the experiment are considered and data consistency checks are discussed. It is found that the resulting x-ray pair distribution function is smoothly varying in real space and shows no evidence of small peaks in the 3–5 Å region. Our results are in contrast to the recent findings reported in Petkov et al 2012 J. Phys.: Condens. Matter 24 155102.
