在比色分析中,由指数曲线函数方程转换的直线化回归方程的图形,是表达指数曲线相关的最佳直线。它可以消除由绘制标准曲线引起的人为误差,并提高测定结果的精度。应用程序计算器建立的指数曲线的直线化回归方程和一元线性回归方程计算测定结果具有相同的精度,但前者的计算过程比之后者的计算过程更为简便,借助程序计算器建立和贮存指数曲线的直线化回归方程只需要几分钟,计算待测溶液的浓度只需几秒钟。
In colorimetric analysis, the graph of the linear regression equation converted from the exponential curve function equation is the best straight line for expressing the exponential curve. It eliminates the human error caused by drawing a standard curve and improves the accuracy of the measurement results. The linear regression equation of the exponential curve established by the application calculator has the same precision as the calculation results of the univariate linear regression equation. However, the calculation process of the former is more simple than the latter, and the exponential curve is established and stored by the program calculator The linear regression equation takes only a few minutes to calculate the concentration of the test solution in just a few seconds.
