论文摘要
贾卡德（Jaccards）的理论描述了冰中的离子和bjerrum缺陷的运动。该理论的标准描述基于一个链模型，描述了这些缺陷沿着水分子的稳定链的运动。但是，该模型包含几个基本矛盾，并且不会导致确切的方程式。我们提出了一个基于缺陷的电填充的替代模型。冰样本的极化有利于与相同缺陷的电漂移相反的这些缺陷方向。这种简单的方法不仅会导致正确的方程式，还提供了对缺陷动力学的更好理解。
Jaccards' theory describes the movement of both ionic and Bjerrum defects in ice. Standard descriptions of the theory are based on a chain model describing the movement of these defects along well-oriented chains of water molecules. However, this model contains several fundamental contradictions and does not result in the exact equations. We present an alternative model based on the electrodiffusion of the defects. The polarisation of the ice specimen favours these defects orientations that diffuse opposite to the electric drift of the same defect. This straightforward approach not only results in the correct equations, it also provides a better understanding of the defects' kinetics.
