What is the serial number of the reference journal for writing papers?

Yes, the example you cited is one of the citation standards for academic or dissertation, namely: author, title [J], publication name, publication year, volume (issue): starting and ending page numbers. Therefore, 1998.(3) refers to the third issue of 1998.

here are some reference specifications, which I hope will be helpful to you.

1. Author of periodical. Title [j]. Title, publication year, volume (issue): page number

2. Author of monograph. Title [m]. Version (the first edition is not recorded). Place of publication: publisher, publication year: page number

3. Author of proceedings. Year of publication: page number

4. Author of dissertation, title [d], place of preservation, 〔N〕． of preservation, year

5. Title of patent document [p], country, type of patent document, patent number, date of publication

6. Report author, title [r], place of preservation, year
