摘要
在连续函数变差相关理论基础上,为了更好地描绘实验或实际测得的曲面数据,本文引入离散曲面变差的概念,并提出了离散曲面变差的计算方法。针对两组不同的离散曲面数据,计算它们在不同尺度下的变差以及尺度和变差的双对数图,比较了两组离散曲面的维数与变差关系。研究结果表明:本文提出的离散曲面变差的计算方法是可行的,可以作为计算离散曲面变差的一种方法。
In order to better describe the experimental or actual measured surface data,the concept of discrete surface variation was introduced on the basis of relevant theories of continuous function variation in this paper.The calculation method of discrete surface variation was put forward. In view of the two groups of different discrete surface data,their variations under different scales were calculated,and diagrams of the scale and the variation of double logarithmic were given. The dimensions of the two groups of discrete surface and variation relation were compared. The results show that the method of calculating the discrete surface variation is feasible and can be used as a method of computing discrete surface variation.
