摘要：

In general, the dependence of the logarithm of the emissivity upon wavelength is usually used in the data processing measured by multi-wavelength pyrometer. In this paper, a new method for automatically searching the mathematical model between emissivity and wavelength was proposed, The effects of measurement errors on the temperature and emissivity were emphatically analysed when the above-mentioned method was used, The results of computer simulation match extremely well with the assumed data, The theory developed here has been shown to be an effective method to calculate both temperature and emissivity.
