Specific arrangement mode of reference 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 a document is cited repeatedly, it will be marked with the same serial number. Generally speaking, the page number (or page number range) of a document cited once is listed in the references after the text.
If the number of references appearing as text needs to be followed by page number or page number range, the page number or page number range should also be superscript. Authors and editors need to carefully check the number of references under the sequential coding system, so that the number is consistent with the list of references after the indicated documents are exactly the same. In addition, the page number or page number range of references should also be accurate.
