使用由纯水和 NaCl、NH4OH 和 HF 水溶液生长的圆柱形冰样品进行晶粒生长实验。溶质浓度从 10-1 M 变化到 10-4 M，退火在 -2°C 到 -16°C 范围内进行。获得的结果表明，当向冰中添加溶质时，晶粒生长速率增加。这种行为可能与晶界结构和迁移率的变化有关。
Grain growth experiments were carried out using cylindrical ice samples grown from pure water and from water solutions of NaCl, NH4OH and HF. Solute concentrations were varied from 10-1 M to 10-4 M and annealing was performed within the range -2°C to -16°C. The results obtained show that the grain growth rate is increased when solutes are added to ice. This behaviour may be related to changes in grain boundary structure and mobility.
