摘要
以丁二酮肟分光光度法测定水中镍的标准曲线为例,运用最小二乘法对标准曲线进行拟合,得出,。因x即吸光度趋于零时,镍含量y可能为负数,不符合客观实际,所以对其标准曲线的拟合进行了改进,对如何改进进行了探讨。
This paper deals with the method of applying least squares techniques for standard curve fitting of nickel water via the linear regression,as shown in spectrophotometry.The result is,.Due to the absorbency（x） is close to nil,the content of nickel is likely to negative that does not tally with the fact,so ameliorate the standard curve fitting.In addition,discussion has been made below of how to ameliorate the standard curve.
