| 摘 要： | 本文应用太赫兹时域光谱技术研究了不同型号汽油在0.28-2.1THz波段的光学性质,采用快速傅里叶变换得到样品的吸收谱和折射率谱.同时,运用傅里叶变换红外光谱装置测定了样品的中红外吸收谱.比较两种实验结果可知,不同型号汽油在太赫兹波段有明显的峰位位移和相对峰强改变,且吸收谱带展宽,说明样品在太赫兹波段比在中红外波段更具有吸收活性.太赫兹技术可作为中红外等光谱技术的互补手段,研究汽油组成的特性及鉴别其结构的细微变化等.

| Abstract: | Optical properties of gasoline with different octane number have been investigated in 0.28-2.1 THz range using the terahertz time-domain spectroscopy （THz-TDS）. Different drops in amplitude and delays in time suggested different physical property. Different from the results from Fourier transform infrared spectroscopy, distinguishing peak position and intensity of different gasoline can be obtained in THz region, indicating that gasoline is more sensitive in the THz range than in infrared. THz-TDS can be used as a complementary to infrared for composition and characteristic analysis of gasoline. |
