摘　　要：目的:明确艾灸光谱中是否含有太赫兹波段、揭示艾灸太赫兹光谱特征。方法:运用太赫兹相机,分别对成像镜头前放置聚乙烯塑料袋及其注水前后的燃着艾灸进行太赫兹成像检测。借助太赫兹光谱仪,对不同直径、年份、材质的四种燃着艾灸分别进行太赫兹光谱检测并以香烟为对照。结果:①艾灸光谱包含太赫兹波段。表现为:艾灸点燃后可出现燃着区域轮廓的太赫兹图像;成像镜头前放置无色透明聚乙烯塑料袋后,太赫兹成像效果未被明显削弱;袋内注入水后则无法成像。②艾灸太赫兹光谱涉及2.5~10 THz,波长范围涵盖112μm~3 mm。③太赫兹光谱相对强度与艾灸直径、年份和艾绒含量有关。表现为:直径18 mm艾灸燃着后太赫兹相对强度高于直径7.3 mm香烟,也高于直径5 mm艾灸;五年艾绒制成的艾灸,燃着后太赫兹相对强度高于一年艾绒制成的艾灸;纯艾绒制成的艾灸,燃着后太赫兹相对强度高于同等直径和年份的普通艾条。④香烟和艾灸点燃产生的太赫兹光谱相对强度不同,但光谱特征与空气吸收谱高度相似。结论:艾灸燃烧光谱中存在着太赫兹波段,艾灸太赫兹光谱相对强度与燃着艾灸的直径、年份和灸材相关。Objective:To clarify whether burning moxibustion contains terahertz spectrum and reveal the characteristics of moxibustion terahertz spectrum.Methods:Terahertz imaging detection was performed on the burning moxibustion before and after placing polyethylene plastic bags and water which facing the terahertz camera lens,respectively.Four kinds of burning moxibustion with different diameters,years and materials were analyzed by terahertz spectrometer and cigarettes were used as the control group.Results:①Moxibustion spectroscopy contains the terahertz band.Terahertz images may occur after moxibustion ignition,which are similar to the outline of the combustion area.After placing a colorless transparent polyethylene plastic bag in front of the imaging lens,the terahertz imaging effect is not significantly weakened.Terahertz images cannot be imaged after injecting water into the polyethylene plastic bag.②Moxibustion terahertz spectrum includes the frequency of terahertz waves from 2.5 to 10 THz,and the range of wavelength from 112μm to 3 mm.③Relative intensity of terahertz spectroscopy is related to moxibustion diameter,year and moxa content.The terahertz relative intensity after ignition of moxibustion with a diameter of 18 mm was higher than that of cigarettes with a diameter of 7.3 mm and also higher than that of moxibustion with a diameter of 5 mm.The relative intensity of terahertz after ignition of moxibustion made from five-year moxa was higher than that of moxibustion made from one-year moxa.The intensity of terahertz after ignition of moxibustion made from pure moxa was higher than that of common moxibustion with the same diameter and year.④Terahertz spectroscopy relative intensities produced by cigarette and moxibustion ignition are different,but which spectral features highly similar to air absorption spectra.Conclusion:There is terahertz spectrum in burning moxibustion.The relative intensity of the moxibustion terahertz spectrum is related to the diameter,age and material of the moxibustion.
