摘要
本文应用广义逆解法,将多变量散乱数据曲面(超曲面)拟合,把拟合后的曲面(超曲面)作为多变量问题等值线形成的数学模型,从而把超曲面、等值面、等值线这些几何概念,与等值线形成的物理意义结合起来,使人们能够从离散数据中揭示出所蕴含的物理规律。
Employing the generalized inversesoloing algorithm and fitting multivariable surfaces(hypersurface)to scattered data.A mathematical model for generating isograms is obtained.Thus,the geometrical concepts of hypersurfaces,contour planes,isograms etc.are connec-ted with the physical process of generating isograms,and it becomes feasible to reveal theimplicit physical law from scattered data.
