摘要
利用IRTracer-100傅里叶变换红外光谱仪测量了柴油介质的光谱数据,根据光谱数据反演柴油介质的光学常数,分析不同温度对柴油透射光谱及光学常数的影响。研究结果表明:在波段400～2000cm~(-1)范围内存在470cm~(-1)、1377cm~(-1)、1454cm~(-1)3个吸收区域;柴油的折射率对光谱的选择性很强,吸收指数呈现波动性变化;在波段905～1200cm~(-1)范围内,柴油的折射率随波长增加波动性较大,吸收指数随温度升高而明显下降,25℃波数为939cm~(-1)时吸收指数存在最大值0.01523;在波段1800～2100cm~(-1)范围内,柴油的折射率随温度升高而增大,吸收指数在2085cm~(-1)存在最大值0.00738。
The spectral data of diesel oil medium were measured by IRTracer-100Fourier transform infrared spectrometer.The optical constants of diesel oil medium were retrieved based on spectral data,and the effects of different temperatures on transmission spectra and optical constants of diesel oil were analyzed.The results show that:There are 3absorption regions,such as 470cm~(-1),1377cm~(-1),1454cm~(-1),in the range of 400～2000cm~(-1).The refractive index and absorption index of diesel are very selective to the spectrum,and the difference in the range is larger in the range of different wavelengths.At the wavelength of 905～1200cm~(-1),the refractive index of diesel increased with the increase of wavelength.The absorption index K decreased significantly with the increase of temperature.When the wave number at 25℃was 939cm~(-1),the absorption index had a maximum value of 0.01523.In the band of 1800～2100cm~(-1),the refractive index of diesel increases with the increase of temperature,and the absorption index has the maximum value of 0.00738in the range of 2085cm~(-1).
