1. keywords are words or phrases that reflect the theme of the paper, usually arranged below the abstract, and the font size is different from the text. Generally, each article can choose 3~8 keywords, and multiple keywords are separated by semicolons, which are arranged from big to small according to the extension (conceptual scope) level of the entry.

Keywords are generally noun words or phrases, and in some cases there are verb words or phrases. English keywords corresponding to Chinese keywords should be marked. Chinese comes first, foreign language comes last. Chinese keywords are marked with "keywords:" or "[keywords]"; English keywords are marked with "keywords:". Key words should be selected from the National Standard Chinese Thesaurus as far as possible; Important terms and names of new disciplines, regions, people and documents that are not included in the glossary can also be used as keywords. Keywords should be general technical terms that can cover the main content of the paper. 2. Method of selecting keywords Generally, the method of selecting keywords is: after the author finishes writing the paper, he chooses from its title, hierarchical title and text (high-frequency words and keywords).

main body

1. In order to achieve the purpose of clear hierarchy and clear context, the text is often divided into several large paragraphs. These paragraphs are called logical segments, and a logical segment can contain several small logical segments, and a small logical segment can contain one or several natural segments, so that the text forms several levels. The level of the paper should not be too much, generally not more than five levels. 1. The norms and functions of references In order to reflect the scientific basis of the article, the author's earnest attitude of respecting other people's research results and the sources of providing relevant information to readers, a list of references should generally be listed after the text.

Citation should be based on original documents and first-hand information. All quotations from other people's opinions or words, whether published or not, whether printed or electronic, must indicate the source or be annotated. All references should be truthfully stated. The introduction, comments, quotations and annotations of existing academic achievements should be objective, fair and accurate. False labeling, forgery and tampering with documents are all academic misconduct.

Express gratitude/gratitude

A scientific research achievement or technological innovation is often not accomplished by one person, but also needs the support and help of human, financial and material resources from all sides. So many papers have listed "thanks" at the end. I am mainly grateful for the help I got in the process of completing my thesis, which is a sign of humility and courtesy in academic circles.
