3 terms and units of measurement

3.1 terminology The following terms and other terms defined in JJF1001-2011 and JJF1007-2007 apply to this Code. 3.1.1 [effective] spectral brightness temperature [effective] spectralradiancetemperature At a given wavelength, the luminance of the spectral radiation is equal to that of the blackbody of the effective spectral radiation temperature. Note. 1 indicates the effective spectral brightness temperature, the wavelength should be stated. 2 can be referred to as spectral brightness temperature or brightness temperature when it is not confusing. 3 The actual measured amount of single-band radiation thermometer can be regarded as the effective spectral brightness temperature at its effective wavelength. 4 definition of the classic brightness temperature. heat radiator and blackbody in the same wavelength of spectral radiation equal brightness, said the black body temperature The temperature of the heat radiator at the wavelength of the wavelength. In practical applications, the thermometer in a finite spectral range of measurement results, also known as For the brightness temperature [JJF1007-2007, 5.20]. In the case of environmental radiation can be ignored, the effective spectral brightness temperature That is the classic brightness temperature. 3.1.2 [effective] brightness temperature [effective] radiancetemperature The temperature of the blackbody in the given wavelength range, the radiation intensity is equal to the effective radiation brightness of the measured heat radiator.
