【Abstract】 A universal model of emissivity function is established in a short-band. According to this model of emissivity, the equations of temperature measurement can be developed by choosing tri-wavelength, and the coupling effect of temperature and emissivity of the measured object will be solved, so that the true temperature can be accurately determined in measurement. In dealing with the measured data, the effect of optical measuring parameters has been avoided with the ratio-radiation, the temperature measurement system is realized by simple calculation and without any additional rectification.更多还原
