What is an abstract of a paper? How to write.
1, review papers (including meta-analysis)? Through the collation, synthesis and evaluation of published materials, as well as the investigation of current research progress to clarify the problem.

2. To write detailed information about a topic (a topic or a field), we should not only point out the development background and work significance, but also point out the reasons for the success or failure of the research with the author's critical comments.

Research trends and the latest progress, but also on this basis to comment, predict the development trend and application prospects. Therefore, the writing format of the summary is diversified, except for the title, signature, abstract and keywords (these four parts are the same as general scientific papers), which generally include four parts: preface, body, abstract and reference, of which the first three parts are the body of the summary and the latter part is the basis for writing the summary.

Writing requirements:

1, cut to the chase, don't beat around the bush. Avoid long-winded narration of historical origin and research process.

2, concise, highlight the key points. We shouldn't talk too much about the familiar common sense content of colleagues and textbooks. When it is really necessary to mention other people's research results and basic principles, we only need to mark them in the form of quotations. In the introduction, when putting forward the work and opinions of this paper, we should make the meaning clear and the language concise.

3. Reviewing the history should be focused, and the content should closely follow the title of the article, introduce the background around the title and summarize it in a few words; Don't write out the methods and results and don't discuss them when prompting the methods used; Although the contents of past documents can be quoted appropriately, they should not be listed in detail, and the preface should not be written as the historical development of research.

Don't write the preface as a small summary of the literature, let alone repeat the common sense content already in the textbook or known by researchers in this field.

4. Respect science and seek truth from facts. In the preface, we should properly evaluate the value of the paper, seek truth from facts and use scientific words. For the innovation of this paper, it is best not to use inappropriate self-evaluation such as "This study is the first report in China", "Filling the domestic blank", "High academic value", "This study has not been reported in China" and "This study is at the leading level at home and abroad".

5. The content of the introduction should not be the same as the abstract, so be careful not to use polite words, such as "a little knowledge", "limited level", "please correct me" and "throwing a brick to attract jade"; It is best not to discuss the preface in sections, not to illustrate and list, not to deduce and prove formulas.
