图4. 非晶态固体中一种特定的短程Voronoi多面体结构, 可以对应于非常宽频的激活能分布, 即不存在直观的、一一对应的短程结构性能关联. 上、下图分别对应于Cu原子与Zr原子为中心的、前4种最频繁出现的Voronoi多面体结构的激活能分布
Fig. 4. A specfic short-range Voronoi structure corresponds to wide range of activation energies, i.e. there does not exist a straightforward, one-to-one structure-property correlation in amorphous solids. The upper and bottom panel denote those clusters which are centered at a Cu, or Zr atom,respectively. Only the spectra of activation energies for the most four frequent Voronoi polyhedra are shown
