摘    要:研究了近红外光谱测定NEPE胶中硝化甘油、丁三醇三硝酸酯、聚乙二醇含量的方法,采用相关系数、显变分析、间隔偏最小二乘法、遗传算法等方法选择波长,对相关实验条件和影响因素进行了研究.实验结果表明,数据平移处理可以有效改善样品吸光度与浓度之间的相关性;遗传算法选择波长优于相关系数法和间隔偏最小二乘法,显变分析不适合于本项研究;近红外光谱法快速测定NEPE胶组分含量的结果与标准分析方法的测定结果一致,两者相差小于1%;水分含量的变化、正常加热操作对NEPE胶组分含量测定的影响不明显.

关 键 词:粘合剂  近红外  组分含量

Abstract:The method to determine the contents of NG,BTTN and PEG in NEPE binder was studied with NIR,based on the correlation coefficient,salience variety analysis,interval partial least square(iPLS) or genetic algorithm(GA) to select wavelength.The related experiment conditions and effect factors were studied as well.The experiment results show that spectral data shift transform can improve the correlation between absorbance and concentration of samples.The GA was better than both of the correlation coefficient met...
