对红外光谱定量分析中的标准添加法进行了误差分析，提出了一种新的数学处理方法，使标准添加法的误差大为降低，准确度得到提高。用简单的苯－ 氯仿二元体系对此法进行了验证。
The error analysis of the standard addition method in the quantitative analysis of infrared spectroscopy was carried out. A new mathematical method was proposed to reduce the error of standard addition method and improve the accuracy. This method was verified with a simple benzene-chloroform binary system.
