2. The specific arrangement of sequential coding system. References are continuously 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.

3. 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).

4, in square brackets (only numbers, no words and characters such as "p" or "page"; 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.

5. 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.
