| 摘 要： | 介绍了当一个变量随另一个变量变化而变化时,按建立的数学模型进行统计分析,利用最小二乘法经过回归计算,得到数学模型方程参数的数学算法及处理过程,描述了利用计算机手段建立并实现因变量随自变量改变的关系曲线。并以水位流量关系曲线为例,介绍依据实测的样点的散布图,得到拟合幂指数方程参数及关系曲线的计算机实现效果。

| Abstract: | The mathematics arithmetic and processing procedure of arith model were introduced, which came from regression calculation by least-square method and the statistic analysis to the founded model when a variable changed following another. Then the relation curve of a variable changing followed the independent variable was described, which was founded and realized by computer. And taking the water level flux relation curve as an example, the computer realized effect on fitting power index parameter and relation curve was introduced, which was calculated according to the spots dispersing map. |
