The theoretical analysis and experiment of the method for measuring natural surface emissivity
自然表面比辐射率测定方法的理论分析和实验

In this paper, the method of measuring the natural surface emissivity is analysed and the ex-periment result reported. Theoretical analysis shows that the Jing's method will ovrestimate the emissivity and underestimate the surface temperature. Some improvements have been made to obtain the more realistic surface emissivity. Using the improved method, the surface emissivities for several underlying surfaces were measured over the HEIFE (Heihe Field Experiment) area.
