在300和210 K温度下，对MCM 41-S15中的水进行了氢同位素替代的中子衍射实验。在微观水平上使用修订版的经验潜在的结构细化技术的数据进行分析。据发现，基板上的水结构的影响是不可忽略的，并取决于温度：由于几何约束和对称性破缺引起的壁，与相应的体相比较是不直接和标准的分析，应取代一个更合适的。
Neutron diffraction experiments with hydrogen isotope substitution on water confined in MCM41-S15 have been performed at temperatures of 300 and 210 K. Data are analyzed at a microscopic level using a revised version of the empirical potential structure refinement technique. It is found that the influence of the substrate on the water structure is not negligible and depends on the temperature: owing to the geometrical constraints and the symmetry breaking induced by the wall, comparison with the corresponding bulk phases is not straightforward and standard analysis should be replaced by a more suitable one.
