摘要
研究了近红外漫反射技术快速测定混合炸药组分含量的新方法。以偏最小二乘法建立了混合炸药中HM X（A）、复合黏结剂（氟橡胶B＋塑料C）、聚四氟乙烯（D）、石蜡（E）5个组分的定标模型,并对模型进行了内部交互验证和外部检验。结果表明,5种模型准确度和精度较高,交互验证相关系数（R）为0.9311-0.9874,交互验证均方根（RM SECV）为0.100-0.582,预测标准偏差（SEP）为0.069-0.371;t检验也表明新方法与化学法无显著差异。新方法快速、无损,结果可靠。
A novel method for fast determining the content of five components in composite explosive composed of HMX, composite hinder, polytetrafluoroethylene and wax is studied by near infrared diffuse reflectance spectroscopy. Models are established with PLS regression and then are validated by cross-validation and external validation. The results indicated that the five models have considerable accuracy and precision. The correlation coefficient of cross-validation is 0. 931 1 to 0. 9874,and the RMSECV is 0. 100 to 0. 582. The SEP of external validation is 0. 069-0. 371 ,and the t test result shows no obvious difference beteen NIR method and the chemical analysis. The new method is fast, non destructive and accurate.
