Claim 6:
7. The method for statistical distribution characterization of dendritic structures in original position of single crystal superalloy according to claim 1, wherein the dendritic structures are automatically counted, partitioned and analyzed in combination with image processing software; a concentration threshold is preset for the two-dimensional element content distribution map of a characteristic element so that the characteristic elements with the content above the concentration threshold are highlighted, to obtain the changed two-dimensional content distribution map; the changed two-dimensional distribution content map is binarized to obtain a binarized image; and the binarized image is partitioned and analyzed to obtain the number and the average spacing of the primary dendrites in different regions of the dendritic structures.
