In academic papers, references are an indispensable part, and periodical papers are one of the most common citation sources. When quoting periodical papers, it is necessary to write references in a certain format so that readers can find the cited documents quickly and accurately. This paper will introduce the format of periodical references. There are two basic formats of periodical references: author year system and numbering system. The author's year system refers to the citation information of documents with the author and publication year as the main signs, while the digital system refers to documents with digital identifiers. In these two formats, the author year system is more common, which will be illustrated as an example below.

In the author year system, a complete periodical reference contains the following information: author, document name, periodical name, publication year, number of volumes, number of issues, starting page number and ending page number. The format of the full log reference is as follows:

Author. (year). Literary titles. Journal name, volume number (issue number), starting page number-ending page number.

Among them, the author can be a single author or multiple authors, and if there are multiple authors, they are separated by commas. The title of the document should be as concise as possible, and the name of the journal should be consistent with the name listed on the journal website or publication. Volume number and issue number can be found on the cover or website of the journal, and the starting and ending page numbers should indicate the specific page range.

Here are some examples:

Chen Qinghua, Ma Xuequan. (2020). Construction and application of knowledge map based on triples. Computer Engineering and Applications, 56 (13), 167- 173.

Liu Wenbiao, Wu,, et al. Adaptive flow control based on deep reinforcement learning. Journal of Electronics, 47( 10), 242 1-2427.

Liang Jing, Huang Jie. (20 18). Research on aircraft fault detection algorithm based on deep learning. Electronic design engineering, 26 (3), 140- 144.

The above are three examples of the format of periodical references, from which readers can learn how to write references according to the literature information.

In short, the format of periodical references should be as concise and accurate as possible, so as to facilitate readers to find the cited documents quickly. At the same time, we should also follow the corresponding academic norms and requirements when quoting references.
