摘　　要：提出了一种基于可调发射率红外测温仪测量不透明材料波段法向发射率的方法,并研制了相应的测量装置,同时对测量装置进行了不确定性分析。在此基础上,利用该测量装置对两种不同材料的波段发射率进行了测量,并与利用傅里叶变换红外光谱分析仪(FTIR)的能量法所测得的相同温度、相同波段内的光谱发射率进行对比,二者结果符合较好。该方法可用于近似漫射灰体不透明材料的波段法向发射率测量,具有使用简便、测量速度快、测量成本低、适用范围广等优点,可用于现场在线测量。This article proposes an opaque material band normal emissivity measurement method based on the emissivity adjustable infrared thermometer,and develops the relevant measuring apparatus.At the same time,the uncertainty analysis is carried out on the measuring apparatus.On this basis,the measuring apparatus is applied to measure the band emissivity of two different materials,and the Fourier transform infrared spectroscopy（FTIR）is used to measure spectral emissivity in the same band under the same temperature based on the energy method.The results matches well.This method can be used to measure the band normal emissivity of the diffuse gray opaque material approximately.It has many advantages,such as easy to use,high speed,low cost and wide range of application.The method can also be used to the on-site online measurement.In addition,the measurement errors of the method are analyzed.
