The footnote method of citing references in the annotation of graduation thesis references requires that numbers be enclosed in brackets, which need to be added manually, and references need to be cited many times in the literature.

All materials cited in the paper must have footnotes in the same format as references, but the requirements are more stringent, and the source page number should be indicated.

Footnotes are smaller than No.5, and they are "① type", all of which are "superscript" in the text, and each page is numbered separately.
