请问大家关于voronoi多面体分析的一个问题
|
|
这是文献中对于voronoi多面体分析的说明： Voronoi tessellation divides space into close-packed polyhedral around atoms by constructing bisecting planes along the lines joining the central atom and all its neighbours . The Voronoi index ( n 3 ; n 4 ; n 5 ; n 6 ) is used to characterize the geometry feature of atomic clusters, where n i denotes the number of i-edged faces of a Voronoi polyhedron. In our analysis, a cutoff distance of 5 Å was chosen so that the Voronoi index distribution was converged. 请问，在voronoi分析方法中需要截断距离吗？这个截断距离有什么用，通常如何选取？ |
