Abstract

In a previous paper we reported the lattice constants and thermal expansion of normal and deuterated ice Ih [Röttger et al. (1994). Acta Cryst. B 50, 644-648]. Synchrotron X-ray powder diffraction data were used to obtain the lattice constants and unit-cell volumes of H(2)O and D(2)O ice Ih in the temperature range 15-265 K. A polynomial expression was given for the unit-cell volumes. It turns out that the coefficients quoted have an insufficient number of digits to faithfully reproduce the volume cell data. Here we provide a table with more significant digits. Moreover, we also provide the coefficients of a polynomial fit to the previously published a and c lattice constants of normal and deuterated ice Ih for the same temperature range.

H2O和D2O冰Ih在10 ~ 265 K间的晶格常数和热膨胀。附录。

在之前的论文中，我们报道了正常冰和氘化冰的晶格常数和热膨胀[Röttger et al.(1994)]。Acta结晶。[j].中国农业科学，1994,18(2):444 - 448。利用同步加速器x射线粉末衍射数据，得到了H(2)O和D(2)O冰Ih在15 ~ 265 K范围内的晶格常数和单胞体积。给出了单位胞体积的多项式表达式。事实证明，引用的系数没有足够的位数来忠实地再现卷单元数据。这里我们提供了一个具有更多有效数字的表。此外，我们还提供了在相同温度范围内正常冰和氘化冰的晶格常数a和c的多项式拟合系数。

期刊介绍： Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials publishes scientific articles related to the structural science of compounds and materials in the widest sense. Knowledge of the arrangements of atoms, including their temporal variations and dependencies on temperature and pressure, is often the key to understanding physical and chemical phenomena and is crucial for the design of new materials and supramolecular devices. Acta Crystallographica B is the forum for the publication of such contributions. Scientific developments based on experimental studies as well as those based on theoretical approaches, including crystal-structure prediction, structure-property relations and the use of databases of crystal structures, are published.
