本文从辐射测温法理论出发,讨论了名义温度出视在名义温度的概念,强调指出;名义温度的亮温、全辐射温度从理论上讲不可能高于真温;但在环境温度辐射的影响下,温度计的读数——视在名义温度(视在亮温、视在全辐射温度)是可能高于真温的。本文还讨论了有效波长概念和温度计的波段选择。注;本论文曾在“全国第二届气动实验非接触测量学术交流会”上(l984.0杭州)发表,略有删改。
Based on the theory of radiation thermometry, this paper discusses the notion of nominal temperature depending on the nominal temperature and emphasizes that the bright temperature and full radiation temperature of nominal temperature can not theoretically be higher than the true temperature. However, at the ambient temperature Under the influence of the thermometer readings - nominal apparent temperature (apparent brightness temperature, apparent total radiant temperature) is likely to be higher than the real temperature. This article also discusses the concept of effective wavelength and the band selection of a thermometer. Note; This paper was published in the Second National Symposium on Non-contact Measurement of Pneumatic Experiment (l984.0 Hangzhou) with a slight deletion.
