It is found that,in a first-order differential Raman spectrum,almost all noise peaks are confined within a narrow horizontal band-like region with the base line going through its middle,whereas thesignal peaks shoot up and down much far beyond the region.Based onthis property,a new peak searching method with the aid of first-order differentiation is suggested.In this paper,a R_spectrumpeak labelling program for SPEX 1403 laser spectrometer with DMIBcomputer is reported.The result of peak labelling sho...

For the examination of Multispectral radiation thermometry with first-order linear emissivity model:(1) the best MRT examined wavelength range for unoxidized aluminum alloys is from 3 m to 4 m;(2) unoxidized samples provide better temperature prediction than oxidized samples;(3) if the emissivity model can well represent the real emissivity behaviors, the more accurate inferred temperature can be achieved.
