辐射测温的广义有效亮度温度

针对实际测温中的问题和经典亮度温度理论的不足,提出了以灰体为参照辐射体的广义有效亮度温度概念;利用等效波长理论阐述了带通辐射温度计测量的"主观"特性(积分广义有效亮度温度)与表面有效辐射的"客观"特性(广义有效亮度温度)的关系;分析归纳了广义有效亮度温度的特性以及它与广义亮度温度、有效亮度温度和经典亮度温度之间的关系。广义有效亮度温度理论是对以黑体为参考辐射体的经典表观温度理论的发展,能够在理论上表达和解释亮度测量辐射温度计的实际测量结果,包括在经典理论中缺乏解释的具备发射率修正功能的辐射测温计的测量结果。

Generalized effective radiance temperature in radiation thermometry

Aiming at the problems of actual temperature measurements and the defects of classical radiance thermometry theory,the concept of generalized effective radiance temperature(GERT) is proposed,which adopts gray-body as the reference radiator.Furthermore,the relationship between the "subjective" characteristic(integral GERT) measured by band-pass radiation thermometer and the "objective" characteristic of surface effective radiation(GERT) is exposited with the equivalent wavelength theory.The general characteristics of the GERT and its conversion relationship with the generalized,effective and classical radiance temperatures are summarized.GERT theory is a development of the classic apparent temperature theory with blackbody as the reference radiator,which can express and explain the practical measurement results of radiation thermometers in theory,including the measurement results of the radiation thermometers with the correction function of instrument emissivity.
