【摘要】 利用计算图形学中的Delaunay三角剖分算法及其对偶结构的Voronoi图算法,构建天津市强震台网的Delaunay三角网及Voronoi图。结果表明,Voronoi图可以较直观地显示台网的布局疏密,并为等震曲线绘制的合理性提供判断依据。更多还原

【Abstract】 The algorithms of Delaunay triangulation and its dual structure of the Voronoi diagram in the computation geometry are used to construct the Delaunay triangular network and Voronoi diagram for Tianjin Strong Motion Network.The researches indicate that the Voronoi diagram can intuitively display the distribution density of Tianjin Strong Motion Network,and can provide an exact judgment for the rationality of the isoseismic line.更多还原
