1. Types of references: There are many types of references, mainly monographs [M], papers [C], newspaper articles [N], periodical articles [J], dissertations [D], reports [R], standards [S], patents [P], papers and documents [A].
2. Number of references cited: The number of references in general academic articles should be 20-40, and the number of references in summary articles is generally more than that in research articles. In addition to the review, more than 40 references in other articles show that compared with the research results, the discussion and preface may involve too much content and need to be deleted.
3. citation format in the text of references: the citation format of references in the text depends on the requirements of the school, which is nothing more than numbers and names. Numeric numbering is relatively simple, just number the documents one by one according to the order from front to back.
4. When multiple files are referenced at the same time, list the files in and after the text in chronological order. When the method of name and year is cited in the text, several documents are arranged in chronological order in the text, and then arranged alphabetically after the text. When reference numbers are used in the text, files are listed in numerical order in the text and after the text.
The above is about how to quote references correctly in the paper.
