quantitativeanalysis of edxrf is affected by matrix effect,randomness of nuclear radiation,interaction of elements,statistical fluctuation of radiation detection process,*** algorithm needs to consider many factors,and the established functional relationship is often a complex non-linear ***,effective quantitativeanalysis method has always been the key research direction of spectral resolution *** this paper,we use MATLAB software to study the effect of bpneuralnetwork in quantitativeanalysis of edxrf by establishing the non-linear relationship between the counting rate of each element and the content of a single element in a small *** experimental results show that the smallsampleneuralnetwork can establish a stable structure and be applied to quantitativeanalysis of edxrf,but the number of samples restricts the accuracy of prediction results,most of which can only guarantee 20% to 30% relative error.
