摘要:
乳化炸药水相主成分包括硝酸铵NH4NO3、硝酸钠NaNO3和水。提出了一种基于偏最小二乘法的近红外光谱多组分定量分析模型，根据光谱-理化值共生距离分类法对乳化炸药水相红外光谱数据进行样本划分,从而得到校正集和预测集。采用标准正态变量变换(SNV)+Savitzy-Golay (S-G）卷积平滑+多元散射校正(MSC)+S-G卷积求导预处理手段,对相关性光谱区间进行特征提取,建立乳化炸药水相组分含量的偏最小二乘回归(PLS)预测模型。建立的模型校正集决定系数R2C为0.994,校正集均方根误差RMSEC为1.600 2；预测集决定系数R2P为0.952,预测集均方根误差RMSEP为1.700 9，相对分析误差RPD为3.324 9。结果表明,该定量分析模型的准确性、稳定性和可靠性满足实际需求。近红外光谱法可实现乳化炸药水相主成分含量的在线检测。同时，利用该近红外光谱分析模型测量水相NH4NO3析晶点，平均标准偏差<0.3，相较人工测量稳定性更好，准确度更高。并且利用该模型探究水相配方比例对析晶点稳定性的影响，得出水相中NaNO3最优质量分数为4.0%左右。
