摘要

本文研究了在-5℃条件下带气泡的纯冰样品中晶粒三结的迁移,持续时间近3hs。这使得跟踪晶界(BG)的进展及其与气泡的相互作用成为可能。通过LEICA®光学显微镜获得的连续照片记录了晶粒三重结的演变。同时,利用蒙特卡罗方法进行了数值模拟,得到了BG在冰面上运移的一些物理参数特征。

STUDY OF THE GRAIN BOUNDARY MIGRATION IN A TRICRISTAL PURE ICE WITH BUBBLES
In this paper the migration of a grain triple junction in apure ice sample with bubbles at -5°C was studied for almost 3hs. This allowed tracking the progress of the Grain Boundary (BG) and its interaction with the bubbles. The evolution of the grain triple junction was recorded from successive photographs obtained witha LEICA® optical microscope. Simultaneously, numerical simulations were carried out using Monte Carlo to obtain some physical parameters characteristic of the BG migration on ice.
