A new reflectometer has been developed for measuring thermal radiation characteristics of real surfaces, which are rough and/or contaminated in thermal engineering environments. This reflectometer uses two ellipsoidal mirrors and a semi-transparent mirror, and measures a spectrum of hemispherical reflectance for perfect-diffuse hemispherical irradiation R_<HH> in the visible through nearinfrared spectral region of 0.35-1.1mum. The reflectometer also measures the spectra of the normal-incident hemispherical reflectance R_<NH> and the oblique ring-incident hemispherical reflectance R_<ObH>. This reflectometer is the first instrument to measure the reflectances directly related to the absorptances for heat transfer engineering.Experimental verification has been made on some real surfaces, and theoretical/ modelling studies have been made to back up the principles of the developed measuring technique. Expansion of the measuring spectral region to the infrared , development of the hemispherical transmittance measurement technique and advanced systematic modelling works are recommended for the future study.

研制了一种用于测量热工环境中真实的粗糙表面和污染表面热辐射特性的新型反射计。该反射计使用两个椭球镜和一个半透明镜，并测量在0.35- 1.1 μ m的可见光至近红外光谱区域中的完全漫射半球辐射R_的半球反射率光谱<HH>。反射计还测量了垂直入射半球反射率R_<NH>和斜环入射半球反射率R_的光谱<ObH>。该反射仪是第一台测量与吸收系数直接相关的反射系数的仪器，已在一些真实的表面上进行了实验验证，并进行了理论/模拟研究以支持所发展的测量技术的原理。建议将测量光谱范围扩展到红外，发展半球透射率测量技术和先进的系统建模工作。
