Abstract
Embodiments of the present application disclose a Bragg edge spectrum fitting method and device and electronic equipment. The method comprises: determining neutron transmittance corresponding to each wavelength of neutron beam when a plurality of wavelengths of neutron beams are incident on a target sample; determining a to-be-fitted function corresponding to the Bragg edge spectrum of the target sample; and fitting the to-be-fitted function based on the wavelength and the neutron transmittance of each neutron beam to obtain a target fitting function corresponding to the Bragg edge of the target sample. The technical scheme of the embodiments of the present application solves the problem that the least square method needs to obtain more experimental data for fitting the Bragg edge spectrum and is not accurate enough, realizes fitting of the Bragg edge spectrum in the case of less experimental data, and can more accurately represent sample information.
