According to China Library Classification, or online/query, format: TG3 15.4.

Second, the certificate identification code:

Document identifiers are divided into the following five categories.

A: Academic papers on theoretical and applied research (including summary reports);

B: Practical technical achievement report (science and technology), theoretical study and social practice summary (social science);

C: Articles on business guidance and technical management (including leaders' speeches and special comments, etc.). );

D: General dynamic information (newsletters, reports, meetings, interviews, etc.). );

E: Documentation (including historical data, statistical data, institutions, people, books and periodicals, knowledge introduction, etc.). );

Description:

1) Articles, abstracts, messages, padding, advertisements, notices, etc. that do not belong to the above categories. No document ID is marked.

2) The document identification code of Chinese articles is marked with "document identification code:" or "[document identification code]", such as: document identification code: a.

3) The document identification code of English articles is "Document Code:".

The specification has different requirements for different article formats. Class A articles are required to have Chinese and English titles, work units, abstracts and keywords, as well as the Chinese pinyin of the author's name; Class B and C articles require Chinese titles and author names.

Class A literature is the symbol of periodical quality. The works in periodicals are the core part of periodicals, which have high academic value and are generally classified as Class A documents. Comprehensive articles are generally long, mainly based on Jiang Ji's literature or comments, authoritative and can guide the further development of the discipline, and are classified as Class A.

For abstracts, reports, experience exchanges and other articles, it is difficult to unify the article identification code, some of which are designated as B, and some are treated separately according to the specific circumstances of the article.

Comments, seminars and other general signs are designated as C; Short reports and short stories are generally designated as d.

Generally, the document identification code does not need to be marked by the author, but is divided by the full-time periodical staff according to the content of the article.

At present, there are still some problems in certificate identification code, which need to be further standardized and unified.

Third, the article number

It's the serial number given by the full-time periodical staff, so I can't fill it in myself.
