摘要

本文研究了双晶冰样品中晶界槽的演化过程。该凹槽是由晶粒边界与自由表面的交点形成的。双晶冰样品具有任意取向差，并在-5°C下浸入超纯硅油中以避免蒸发过程。用光学显微镜每17分钟拍摄一次凹槽的照片，持续100小时，并根据这些图像确定凹槽的演变。通过这项研究，可以测量-5°C时冰的表面自扩散系数。

Superficial self-diffusion coefficient in Ih-ICE

The evolution of the grain boundary groove in a bicrystalline ice sample was studied in this work. The groove is formed by the intersection of the grain boundary with the free surface. The bicrystalline ice sample had an arbitrary misorientation and was immersed in ultra-pure silicone oil at -5°C in order to avoid evaporation processes. Photographs of the groove were taken every 17 minutes for 100 hours with an optical microscope and the evolution of the groove was determined from these images. Through this study, it was possible to measure the coefficient of surface self-diffusion of the ice at -5°C.
