Summarize the preface of the paper, and the writing should include the following contents:

Explain the reason and significance of studying this topic. This part should be written concisely. Be sure to avoid writing your feelings and feelings in a long space like a composition, and take pains to talk about the thinking process of choosing this topic.

Ask questions. This is the core part of the preface. This question should be put forward clearly and concretely. Sometimes, it is necessary to write a little historical review, who has done what research on this subject, and what supplements, revisions or developments the author himself will have.

Writing format:

Different from ordinary scientific papers. Scientific papers pay attention to the scientificity of research methods and the credibility of results, with special emphasis on positive results. In order to write detailed information about a topic (a topic or a field), the abstract should not only point out the development background and significance of the work, but also point out the reasons for the success or failure of the research with the author's criticism.

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.
