摘　　要：太赫兹时域光谱技术可以分辨化合物结构上的微小差异并应用于物质检测与分析,为物质的鉴别及更宽有效光谱区的测试提供了新的实验方法。本文采用太赫兹时域光谱（THz-TDS）技术,在室温氮气环境下对固化剂及其固化产物进行了光谱测试,获得了样品在0.2-2.5THz波段的时域光谱,并通过计算得到固化剂及其固化物的吸收谱及折射率谱。实验结果表明,固化剂和固化物在THz范围内敏感,可以根据各自在THz波段的特征光谱得以区分。Terahertz time-domain spectra technology can distinguish minor differences in structure and can be applied to physical testing and analysis.It provides a new experimental method for the identification of the products and the study of spectrum more wide.In this paper the spectroscopy of curing agent（CA） and its products have been investigated in the 0.2~2.5 THz range using terahertz time-domain spectroscopy（THz-TDS） in the environment full of nitrogen at room temperature.The refraction index and the absorption coefficient of CA and its products were calculated.The experimental results showed that curing agent and its products are sensitive and can be？distinguished according to their spectral characteristics in the THz range.
