1. Introduction to document type identification
Document type identification is a symbol that indicates various reference types. The description of references should comply with the provisions of GB 7714-87 "Rules for describing references after the article" and "Data Specification for Search and Evaluation of Chinese Academic Journals (CD-ROM Version)". The author of the paper should use the following document type identification code to list each reference he cited. The type of reference and the type of carrier are indicated. According to the provisions of GB 3469-83 "Document Types and Document Carrier Codes", commonly used document types are identified by single letters, and electronic documents are identified by double letters.

The sorting method of papers in foreign literature citations and references is basically the same as that of Chinese literature; book titles and journal titles are in italics, and journal article titles are in double quotation marks ; It is optional whether to list the document type identification number and the page number of the work (papers must list the first and last page numbers); the year of publication is always listed at the end of the sentence or before the page number (no year sorting method is used). Foreign language documents must be expressed in the original foreign language (a Chinese translation can also be attached in parentheses after the original title), and it is strictly forbidden to express the original meaning of the foreign language only in Chinese.
When writing a paper, if there is a citation, the source of the document must be correctly marked. If not, it is likely to cause infringement. Therefore, everyone must be familiar with the document type identification and the format when writing references. Correct, this will make an excellent paper more perfect.
