I sincerely thank the experts for pointing out the inconsistency between this citation and the illustration, and also thank them for reminding students to check the full text systematically. Students are deeply sorry for such basic mistakes in their papers. In the subsection 3.6.2 on page 71 of the dissertation, the citation sequence in the result description has been changed to figure 3.20, and the number of the corresponding illustration below has been synchronously changed to figure 3.20 to ensure that the citation is consistent with the illustration. At the same time, the students have checked the numbering and citation positions of all the figures in the full text one by one, and revised them into continuous numbering to ensure that the text citation and the figure annotation numbers correspond completely. This systematic verification also makes students fully aware of their own shortcomings in the proofreading of papers, and students will always maintain a rigorous and meticulous attitude in the follow-up scientific research. Thanks again for the expert's careful correction.
