摘　　要：α/β型HMX为同分异构体,物理化学特性有较大差异。为了对α/β型HMX混合物进行定量研究,利用太赫兹时域光谱技术,对α/β型HMX单质与一定比例混合物进行了检测与分析。获得单质α/β型HMX在0.2-2 THz频段标准太赫兹吸收谱,采用线性拟合对α/β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：α/β型HMX混合物在0.82 THz处的吸收强度与α型HMX的含量有较好的线性关系。α/β型HMX混合物在0.82 THz处的吸收特性可以用来进行α/β型HMX的定量检测。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 at0. 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.
