Firstly, the basic principles of the natural neighbor interpolation method based on Delaunay triangular mesh and Voronoi diagram are discussed. Secondly, three interpolation functions, the linear interpolation, the Sibson interpolation and the non-Sibsonian interpolation are analyzed together with their function forms and interpolation formats in detail. Thirdly, the materials state equation database is developed through interpolation programs by this method and the interpolation results are compared with the database itself. Lastly, various characteristics of three interpolation functions, the computational efficiency and the time cost are discussed. Analysis and comparison show that the interpolation results are reasonable and the interpolation computation is very efficient. So this method can well be applied to the development of the materials state equation database., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=针对材料状态方程数据库数据量大、高度离散、分布极不规则的特点及其对插值方法的特殊要求，提出了基于自然邻点插值方法的开发方案。首先论述了基于Delaunay三角网和Voronoi图的自然邻点插值方法的基本原理，其次引入线性插值、Sibson插值和non-Sibsonian插值3种插值函数并详细介绍了各自的函数形式和插值格式，然后采用该方法对材料状态方程数据库进行插值程序开发并与数据库本身对比了插值效果，最后分析了3种插值函数的不同特性并实测了计算效率与耗时。大量分析对比显示，插值结果合理、计算效率较高，表明该方法能够很好地应用于材料状态方程数据库开发中。,
