地层划分中的数学分段法,目前普遍采用的是有序地质量最优分割法,而较简便的简单分段法应用却很少。本文着重对后者进行探讨,提出一些应用意见。Fisher(1958)最早提出有序样品聚类法,国内称最优分割法。将它用于地质上便曰有序地质量最优分割法。它从地层划分的段内特征差异最小、段间特征差异尽可能大的要求出发,寻求地层划分的最优解。在数学上用方差(或离差平方和)来刻划段内和段间
The stratification of mathematical staging method, currently widely used is the optimal quality of the optimal segmentation method, and the simpler simple staging method is rarely used. This article focuses on the latter to discuss and put forward some suggestions. Fisher (1958) first proposed orderly sample clustering method, said the domestic division of the best. It will be used in geological order of the best quality segmentation method. It seeks the optimal solution of stratigraphic division from the point that the difference of features within the segment is the smallest and the difference of features among segments is as large as possible. Mathematically, use variance (or sum of squared deviations) to characterize segments and segments
