水质分析中绘制标准曲线应建立直线回归方程

Plotting Standard Curve Must Bulid Line Regressin Equation in the Water Analysis of Environmental Monitoring

标准曲线在环境监测水质分析中应用相当普遍。本文认为绘制标准曲线应用最小二乘法原理建立直线回归方程,以它所表达的直线是最佳的直线,误差最小。并举例说明建立回归方程运算的程序、方法,以及回归方程的相关分析。

Standard curves are in common use in the water analysis of environmental monitoring. This paper suggests that when a standard curve is ploded. you'd detteruse the principle of leastsquare method to dulid line regr- ession. The line exprcssed by the line regression equation is the best one and its error is the smallest. In this paper, some living examples are given to show the calculating pro- grem and the method for duliding regression equation. and the relation analy- sis of regression equation.
