Reference is the reference in the process of writing articles or works; Relevant literature information resources cited for writing or editing papers and works.

The format is "publication year" of the work or "year, volume (issue)"+":page number (or page number range) of the periodical. For documents cited for many times, list the page number or page number range of each reference in the serial number tag (some publications also regard the information that can indicate the location of the cited documents as page numbers) and put them in square brackets (only numbers are listed, and words and characters such as "P" or "page" are not added.

The line in the middle of the page number range is a half-word line) and marked with superscript. If the serial number of a reference appearing as text needs to be followed by a page number or a page number range, the page number or page number range should also be superscript. Authors and editors need to carefully check the serial numbers of references under the sequential coding system, so that the serial numbers are consistent with the list of references after the marked documents are exactly the same. In addition, the page number or page number range of references should also be accurate.
