本刊曾报道用微机处理吸光光度法、原子吸收和极谱等分析方法的数据,方法快速可靠。但只适用于被测组分所测物理量(如吸光度、波高)和被测组分浓度成线性的特定关系。本法拟扩展检量线,应用到非线性范围,即也能适用于被测组分浓度较大时,浓度与其测定的物理量不呈线性的情况。在本程序设计中,对于检量线的线性和非线性部分,采用分别处理的方法,线性部分使用直线方程, This article has reported the use of computer processing spectrophotometry, atomic absorption spectrometry and other analytical methods of data, the method is fast and reliable. However, it only applies to the specific relationship between the measured physical quantity (such as absorbance and wave height) of the tested component and the linearity of the measured component concentration. This law is intended to expand the calibration curve, applied to the non-linear range, that is, can also be applied to the concentration of the measured components, the concentration and the measured physical quantity is not linear. In this program design, for the calibration of linear and non-linear part of the line, using separate methods, the linear part of the use of linear equations,
