Measuring instruments: infrared spectrometer of Institute of remote sensing, Chinese Academy of Sciences, bomem mr304, Mikron m340 blackbody, bodach BDB blackbody of Beijing Normal University, diffuse reflection gold plate, fluke 50 Series II contact thermometer
Measurement principle: the surface radiation spectrum is measured by infrared spectrometer, and the environmental radiation spectrum is obtained by combining the diffuse reflection gold plate.
