摘要

/型HMX为同分异构体

物理化学特性有较大差异。为了对/型HMX混合物进行定量研究

利用太赫兹时域光谱技术

对/型HMX单质与一定比例混合物进行了检测与分析。获得单质/型HMX在0.2~2 THz频段标准太赫兹吸收谱

采用线性拟合对/型HMX混合的太赫兹吸收谱进行分析建立预测方程

并预测未知样品。结果表明:/型HMX混合物在0.82 THz处的吸收强度与型HMX的含量有较好的线性关系。/型HMX混合物在0.82 THz处的吸收特性可以用来进行/型HMX的定量检测。

Abstract

The physicochemical characteristics of alpha and beta HMX which are isomers are quite different. In order to make a quantitative analysis of alpha and beta HMX mixtures

both pure and mixed alpha/beta HMX were detected and analyzed using of terahertz time-domain spectroscopy (THz-TDS) and THz absorption spectra were obtained. The THz absorption spectra of alpha/beta HMX mixtures were analyzed using linear fitting technique

and the forecast equations were set up to predict unknown samples. The results show that the absorption intensity of alpha/beta mixtures at 0.82 THz range has a good linear relationship with the content of alpha HMX. The absorption characteristics of alpha/beta HMX mixtures at 0.82 THz can be used for quantitative detection.
