APPLE-Ⅱ在化学实验中的应用-实验数据线性范围和方程的确定

Application of APPLE-Ⅱ in Chemical experiment--The determination of linear range and equation for experimental data

本文介绍了一个在 ACS 汉字系统支持下的 BASIC 语言程序,由此程序可确定实验数据的线性范围,并对非线性部分用二次曲线拟合,求出线性和非线性部分的回归系数和回归方程,还可根据需要进行计算,打印,绘图。

The paper introduces a BASIC program that is supported by ACS chinese charecters system.By using the program,the linear range of experimental data can be determined,the nonlinear part can be fitted with quadratic curve,the regression coefficient and the regression equation of linear nonlinear part can be calculated.In accordance with needs,the program can calculate,copy and draw.
