When quoting a national standard, we should find out the serial number and specific name of the standard, and write it with S code as the distinguishing symbol of file type. The format is as follows:
[serial number] standard number, standard name.
For example:
[ 14]? GB/T？ 16 159— 1996,? What are the basic rules of Chinese phonetic orthography? [S]。
