摘要
对单质炸药环RDX以及多种以RDX为主体成分的混合炸药进行了不同形态样品的太赫兹(THz)谱的实验测量.利用太赫兹时域光谱技术(THz-TDS)给出了在0.2-2.5THz范围内炸药样品在不同形态下的吸收系数.结果发现,单质炸药RDX,以及多种以RDX为主体成分的混合炸药具有相同的特征吸收峰;聚乙烯没有特征吸收峰;炸药粉末状样品对THz的吸收相对于片状的样品来说较强.实验结果显示,利用THz-TDS技术可以对单质炸药以及以其为主体成分的混合炸药进行检测和识别.
Experimental measurement and theoretical analysis of THz spectrum for pure material and some mixed explosive samples are introduced. The absorption coefficient of the samples are measured in the region of 0.2-2.5 terahertz by time-domain speetroscopy（THz-TDS）. The absorption spectra are obtained correspondingly. The obtained results indicate the THz-TDS technology can identify the different explosives and roughly analyse the main ingredients of the mixed samples.
