中文摘要: 大多数仪器分析方法都是相对测量方法，需建立分析信号与分析物量值之间的相关关系，因此，正确建立和应用校正曲线是仪器分析中获得准确测定结果的基础。详细讨论了校正曲线的建立和标定方法，校正曲线的属性包括中心实验点的特性、校正曲线的精密度和置信区间、动态范围和线性范围的确定方法等。对校正曲线的应用中常遇到的一些实际问题如测定结果精密度的计算、标准偏差有效数字的确定、测定结果的表示方式等进行了讨论。
Abstract:Most of the instrumental analysis methods are relative measurements and they require to establish some relationships between signals and quantity of analytes in order to obtain exact results of determination. Thus, constructing a right calibration curve is the basis to obtain accurate results from an instrumental analysis. In this paper, the construction, standardization and properties of calibration curves including the characteristic of central experimental point, precision, confidence interval, dynamic and linear range of a calibration curve, etc. were introduced in detail. Some practical problems concerning with the applications of calibration curves, such as calculation of precision, determination of the significant figure of standard deviation as well as expression of determination results, etc. were discussed.
