Phases of ice - Wikipedia
Ice VII is the only disordered phase of ice that can be ordered by simple cooling. (While ice I h theoretically transforms into proton-ordered ice XI on geologic timescales, in practice it is …
Ice VIII substructure - London South Bank University
Ice-eight (ice VIII) forms from ice-seven (ice VII) on lowering its temperature (see Phase Diagram). The hydrogen bonding is ordered and fixed as ice-seven undergoes a proton …
冰VIII - 维基百科，自由的百科全书 - zh.wikipedia.org
冰八（Ice VIII）是由冰七冷却至摄氏5度以下形成的四方 晶体 冰。由于氢原子具有固定位置，因此它比冰七更有序 [1] 。冰八的结构也被认为比冰五更复杂，是冰的所有晶体形态中最复杂的一 …
冰的氢键振动研究 - 物理学报
In Ice VII/VIII and XV/VI, each of which consists of two sublattices, there exist non-hydrogen bond vibrations. These molecular translational vibrations can explain all the far-infrared vibrational …
