| 摘 要： | 曲线拟合是目前数据处理的基本方法之一,通过在微机上用Visual Basic语言编制程序,将实验数据使用最小二乘曲线拟合,构造一个最佳通用多项式拟合模型。再利用得到的函数关系实现对原子荧光光谱仪的实验数据进行多次曲线拟合与仿真,以扩大仪器的测量范围。

| Abstract: | Curve fitting has been one of the methods commonly adopted in data processing. A optimum polynomial fitting model can be constructed with Visual Basic to fit the curve of measured data by using least-square principle. The functional relation so obtained can thus be used to perform multi-order fitting of atomic fluorescence spectral data, so making its measurement rang expanded. |
