描述了一个模型的各向异性晶界特征分布的发展，从最初的随机分布。该模型是基于有偏见的拓扑变化的晶界网络，消除和创建在晶粒生长过程中的边界。晶界能通过改变界面的相对面积来影响这些拓扑变化的速率。该模型预测的晶界特征分布是负相关的晶界能，并与实验观察是一致的。
A model is described for the development of anisotropic grain boundary character distributions from initially random distributions. The model is based on biased topological changes in the grain boundary network that eliminate and create boundaries during grain growth. The grain boundary energy influences the rates of these topological changes by altering the relative areas of the interfaces. The model predicts grain boundary character distributions that are inversely related to the grain boundary energy and are consistent with experimental observations.
