According to the requirements of "China Academic Journals (CD-ROM Edition) Retrieval and Evaluation Data Standard (Trial)" and "China Social Science Journals Arrangement Standard (Revised Edition)", many publications distinguish between references and annotations, and define annotations as "words that further explain or supplement a certain content in the text", which are listed at the end of the article, separated from references or placed in the footer.
The reference materials of extended materials are coded with Arabic numerals in the order in which they appear in the text, and the serial numbers are placed in square brackets. If the file is referenced repeatedly, it is marked with the same serial number in the text. Generally speaking, the page number (or page number range) of a document cited once is listed in the following references.
The format is "publication year" of the work or "year, volume (issue)"+":page number (or page number range) of the periodical. For documents cited many times, list the page number or page number range of each place in the serial number of each reference (some publications also regard the information that can indicate the location of the cited documents as page numbers).
Put it in square brackets (only numbers are listed, and there are no words and characters such as "p" and "page"); The line in the middle of the page number range is a half-word line) and marked with superscript.
