Abstract: A single pulse spectral statistical analysis method for particle size distribution of inclusions on a surface of a metal material is provided. The method includes the following steps: analyzing a surface of an oversized metal material through single pulse discharge continuous excitation scanning to obtain mixed intensity data of spectral intensities of solid solution and inclusions of an inclusion element on the surface of the oversized metal material and a relative frequency distribution diagram; performing peak fitting processing on the relative frequency distribution diagram of the mixed spectral intensities to obtain a relative frequency distribution diagram of the spectral intensities of the inclusion; and correlating particle size information of inclusions of a small sample with distribution data of the spectral intensities of the inclusions to determine a corresponding relation between the particle sizes and the spectral intensities of the inclusions, thereby obtaining a particle size distribution result.
