三次自然样条函数插值法,可以适应分析化学中一些复杂的函数关系(如乳剂特性曲线),也可运用于非线性工作曲线从而扩大工作曲线应用范围。本文采用三次自然样条函数插值方法处理分析化学数据。文中列举了原子吸收分光光度法,发射光谱分析法和离子选择电极电位法的应用。有关的计算运用微型计算机(TRS—80),用 BASICI 语言自编程序,在输入数据后仅在数秒钟即完成插值运算。
The cubic natural spline interpolation method can adapt to some complex functional relationships in analytical chemistry (such as emulsion characteristic curve), and can also be applied to non-linear working curve so as to enlarge the application range of working curve. In this paper, three times natural spline interpolation method to deal with analytical chemistry data. The article lists the application of atomic absorption spectrophotometry, emission spectrometry and ion-selective electrode potential method. The related calculations were made using a microcomputer (TRS-80) programmed in BASICI language to interpolate data in seconds after the data was entered.
