1, collecting literature

Through the process of collecting documents, we can be further familiar with the retrieval methods of scientific documents and the accumulation methods of materials; In the process of searching, we also expanded our knowledge; The preface of the paper is also called introduction, which is a short paragraph in front of the text. The preface is the preface of the paper, which aims to explain the ins and outs of this study to readers, arouse readers' interest in this paper, and play a role in outlining and guiding reading interest in this paper.

2, the beginning

As the beginning of the paper, the introduction briefly introduces the writing background and purpose of the paper, the origin and realistic requirements of the research, as well as the preliminary work and research survey in related fields, and explains the relationship between this research and the preliminary work, research hotspots, existing problems and the significance of the author's work, which leads to the theme of this paper to guide readers.

Step 3 argue

The introduction can also point out the theoretical basis, experimental basis and research methods of this paper, and briefly explain its research content; A few words foreshadow the results, significance and prospect of this study, but there is no need to discuss it. The preface should include: Why do you want to do this research? What is the theoretical or practical basis for setting the topic? Want to innovate? What is the theoretical and/or practical significance? First of all, it is necessary to introduce the historical background and theoretical basis of this topic, the research progress and achievements of predecessors or others on this topic, and whether there are different academic viewpoints in academic circles. Tell the reader clearly why you want to do this research, and the sentences should be concise and straight to the point.

If the research project has never been carried out by others, then the innovation is obvious, and the innovation of the research should be explained. But in most cases, research projects have been carried out by predecessors. At this time, it is necessary to explain the differences and essential differences between this research and that research, rather than simply repeating the work of predecessors.

4. Format

Introduction is also called introduction, preface or introduction. Scientific papers are mainly composed of introduction, theory (results and discussion) and conclusion. The introduction puts forward problems, and this theory analyzes problems and induces and solves them. The introduction is the opening work. It's difficult to write the introduction first, and then read the back. In ancient literary theory, it was known as "crested pig belly and leopard tail". Although scientific papers will not emphasize that the beginning of the article is as beautiful, wonderful and fascinating as the phoenix head, the introduction is the first impression to readers and plays an important role in outlining the full text, which cannot be taken lightly.

Introduction, written in front of a book or an article, is similar to preface or introduction, as an overview or feeling of the book, and also refers to the opening remarks of a symposium, seminar or seminar. Also known as preface, preface or general introduction, it is often used as the beginning of scientific and technological papers to put forward the problems to be studied in the paper and guide readers to read and understand the full text.

The preface of the paper is also called introduction, which is a short paragraph in front of the text. The preface is a general overview of the paper, which aims to briefly describe the content or related background of the paper to readers, arouse readers' interest in this paper, and play an important role in outlining the text and stimulating reading interest. Before writing the preface, we must first clarify several basic questions: What problems do you want to explain through this article, what new discoveries are there, and is there any academic value? After reading the preface, the general reader can clearly know why the author chose this topic for research and the latest progress of this research. Therefore, before writing the preface, we should know as much as possible about the relevant contents, collect the main data of predecessors and others' work, and explain the rationality of this study.
