A method of X-ray spectra construction was founded based on the principle of least square algorithm . 14 different basic spectra were generated with accelerating voltage from 35 kV to 100 kV ,and used in construction of the target spectra .According to the result , the similarity between constructed spectra and target spectra can be controlled to 90% or higher .The main influence factors are lack in quantity of basic spectra ,the distribution of target spectra ,and X-ray fluorescence produced by X-ray source .
