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.

已经开发出一种新的反射计，用于测量热工程环境中粗糙和/或污染的真实表面的热辐射特性。该反射计使用两个椭球面镜和一个半透明镜，测量0.35-1.1mum可见光到近红外光谱区域内完美漫射半球照射R_<HH>的半球反射光谱。反射计还测量法向入射半球反射率R_<NH>和斜环入射半球反射率R_<ObH>的光谱。该反射计是第一个测量与传热工程吸收率直接相关的反射率的仪器。已经在一些真实表面上进行了实验验证，并进行了理论/建模研究来支持所开发的测量技术的原理。建议未来的研究将测量光谱区域扩展到红外、开发半球透射率测量技术和先进的系统建模工作。
