虽然三维多晶中平均体积的生长速率是众所周知的，但单个晶粒的生长速率（通过拓扑和体积分布决定材料特性）尚不清楚。使用三维 Q 态 Potts 模型模拟，我发现晶粒的平均规范生长速率与其面数呈线性关系，并且与其体积无关，这是一个令人惊讶的简单且无法解释的结果。
While the growth rate of the average volume in a three-dimensional polycrystal is well understood, the growth rates of individual grains (which determine material properties through the topological and volume distributions) are not known. Using a three-dimensional Q-state Potts model simulation, I find that the average canonical growth rate of a grain depends linearly on its number of faces and is independent of its volume, a surprisingly simple and unexplained result.
