说明：  校准曲线包括标准曲线和工作曲线，前者用标准溶液系列直接测量，没有经过 校准;而后者所使用的标准溶液经过了与测量校准。 凡应用校准曲线的分析方法，都是在样品测得信号值后，从校准曲线上查得其 (或浓度)。因此，绘制准确的校准曲线，直接影响到样品分析结果的准确。
(The calibration curve includes standard curve and working curve. The former is measured directly with standard solution series without passing through Calibration;The standard solution used in the latter was calibrated to the measurement. Where a calibration curve is applied, the signal value is obtained from the calibration curve after the signal value is measured on the sample (or concentration).Therefore, drawing an accurate calibration curve directly affects the accuracy of sample analysis results.)
