摘要 使用具有三重晶界的冰样本，测量了冰中的相对晶界能量，作为晶粒中 c 轴或 a 轴形成的失配角的函数。研究发现，晶界能的 Read-Shockley 方程对于倾斜在 0° 到 15° 之间的晶界是有效的。通过使用微干涉测量法在覆盖有极薄金属箔的晶界槽处测量冰中固-气晶界槽的角度。将数据与晶界凹槽的镀银复制品测量的数据进行比较。
Abstract Relative grain-boundary energies in ice were measured as a function of mismatch angles made by the c-axes or a-axes in grains, using ice specimens having triple grain boundaries. It was found that the Read–Shockley equation for grain-boundary energy was valid for grain boundaries tilted between 0° and 15°. Angles of the solid–vapour grain-boundary groove in ice were measured by the use of micro-interferometry at grain-boundary grooves covered with extremely thin metalic foil. The data were compared with those measured by a silvered replica of grain-boundary grooves.
