光度法中溶液的浓度与吸光度,用最小二乘法进行一元线性拟合;并表征为一元线性回归方程式:(?)=(?)x+(?)。该回归直线是代表浓度与吸光度之间较为合理的一条直线。
The concentration and absorbance of the solution in the spectrophotometry were linearly fitted by the least squares method and characterized as a linear regression equation: (?) = (?) X + (?). The regression line represents a more reasonable between the concentration and absorbance of a straight line.
