【Abstract】 Voronoi tessellation is a mature mathematical means, which is extensively applied to the fields such as cell biology, geology, physics, ecology, etc. But in the field of astronomy, Voronoi tessellation is not as popular as it is in other fields. Voronoi tessellation serve as a tool for researching the large scale structure of galaxies. The distribution of galaxies is similar to Voronoi tessellation. The samples producted by the means of 2D Voronoi tessellation program are compared with the ACO samples( D =5+6). The results show that they have similar properties in distribution, which prove Voronoi tessellation as a practical means for the large scale structure.更多还原
