摘　　要：目的 探索不同性质艾柱的燃烧红外光谱特征。方法 选取碳化艾柱及不同存储年份(3、5、10年)、不同叶绒比(3∶1、5∶1、10∶1)、不同紧密度(低、中、高)的普通艾柱做为实验样品,使用傅立叶红外变换光谱仪对样品进行燃烧红外光谱测试,并分析峰值与形状等光谱特征;主要指标为特征峰波长,特征峰峰高,红外波段(1.28~25.00μm)、近红外波段(1.28~3.00μm)、ATP能量代谢特征波段(2.0~2.5μm)、人体红外辐射峰值波段(7.5~10.0μm)辐射强度。结果 碳化艾柱燃烧红外单光束光谱峰值位于4.012μm,普通艾柱(存储3年、叶绒比3∶1、中紧密度)峰值位于4.630μm;扣除大气背景辐射后,光谱均在4.241μm或15.000μm附近出现波峰或波谷。与普通艾柱(存储3年、叶绒比3∶1、中紧密度)比较,碳化艾柱红外波段辐射强度更高;特征峰波长更长;特征峰高度更低(P<0.05)。与存储3年艾柱比较,存储10年艾柱的红外波段、近红外波段、ATP能量代谢特征波段、人体红外辐射峰值波段辐射强度更高(P<0.05);存储5年艾柱的ATP能量代谢特征波段辐射强度更高(P<0.05)。与存储5年艾柱比较,存储10年艾柱的红外波段、近红外波段、ATP能量代谢特征波段、人体红外辐射峰值波段辐射强度更高(P<0.05)。与叶绒比3∶1艾柱比较,叶绒比10∶1艾柱的红外波段、近红外波段、ATP能量代谢特征波段、人体红外辐射峰值波段辐射强度更高(P<0.05);叶绒比5∶1艾柱的红外波段、ATP能量代谢特征波段、人体红外辐射峰值波段辐射强度更高(P<0.05)。与低紧密度艾柱比较,中、高紧密度艾柱的红外波段、人体红外辐射峰值波段辐射强度更高(P<0.05)。结论 碳化艾柱辐射强度较强,但其光谱异于普通艾柱,增加普通艾柱的存储年份及叶绒比可以加强艾柱辐射强度,且紧密度适中的普通艾柱更优,为传统艾灸的作用机制研究提供基础。Objective To explore the combustion infrared spectrum characteristics of moxa columns with different properties.Methods Carbonized moxa columns and common moxa columns with different storage years(3,5,and 10 years),different leaf-wool ratios(3∶1,5:1,and 10:1),and different compactness(low,medium,and high) were selected as experimental samples,and Fourier transform infrared spectrometer was used to test the combustion infrared spectrum of the samples,and the spectral characteristics such as peak and shape were analyzed.The main indexes were characteristic peak wavelength,characteristic peak height,and the radiant intensity of infrared band(1.28-25.00 μm),near infrared band(1.28-3.00 μm),ATP energy metabolism characteristic band(2.0-2.5 μm),and human infrared radiation peak band(7.5-10.0 μm).Results The peak value of the combustion infrared single beam spectrum of carbonized moxa columns were 4.012 μm,and the peak value of the common moxa columns(storage for 3 years,leaf-wool ratio 3∶1,medium compactness) were 4.630 μm;after deducting the atmospheric background radiation,both spectrum had a peak or trough near 4.241 μm or 15.000 μm.Compared with common moxa columns(storage for 3 years,leaf-wool ratio 3∶1,medium compactness),the radiant intensity of infrared band of carbonized moxa columns was higher,the characteristic peak wavelength was longer,and the characteristic peak height was low(P<0.05).Compared with storage for 3 years moxa columns,the radiant intensity of infrared band,near infrared band,ATP energy metabolism characteristic band,and human infrared radiation peak band of storage for 10 years moxa columns were higher(P<0.05);the radiant intensity of ATP energy metabolism characteristic band of storage for 5 years moxa columns were higher(P<0.05).Compared with storage for 5 years moxa columns,the radiant intensity of infrared band,near infrared band,ATP energy metabolism characteristic band,and human infrared radiation peak band of storage for 10 years moxa columns were higher(P<0.05).Compared
