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.
Fold the introduction and collect the 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.
Fold the beginning of the introduction
Introduction, as the beginning of the paper, 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, the current research hotspots, existing problems and the author's work significance, which leads to the theme of this paper and guides readers.
Folding introduction argument
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.
Folding introduction 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 is difficult to write an introduction before writing a book. 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.

(1) explain the theme, scope and purpose of the paper;
⑵ Explain the cause, background and brief historical review of related fields of this study (what did the predecessors do? Which ones have not been solved? How's it going so far?
⑶ The expected result or significance of this study;
(4) Introduction is generally not segmented, and its length depends on the content of the paper. The introduction of papers involving basic research is long, and the clinical case analysis should be short. The introduction of most foreign papers is relatively long, generally around 1000 words, which may be related to the strict limitation of the number of words in foreign domestic journals.
The so-called introduction is to set a topic for the writing of the paper, with the aim of leading to the following. Only when the "proposition" is established, it is necessary to continue writing the paper, otherwise the writing of the paper will lose its meaning. The general introduction includes two meanings: first, the background of "topic selection", which explains the position and role of topic selection in this discipline and the research status, especially the existing or unsolved problems in the research. The second is to establish the problems to be solved in this paper according to the existing research situation, which leads to the following.
Fold and edit the writing format of this paragraph.
1) The article is irrelevant and general. Some authors seem to regard the introduction of the paper as a form and a dispensable part, and separate the writing of the introduction from the writing of the text just to add a hat to the paper. It is a common phenomenon to discuss the importance of research in general, even from the position of the industries involved in technology in the national economy, just like the leader's speech. It is the theme of research, and it is also from macro to micro, staying in general terms. Obviously, as a result, readers can't accurately judge the specific value of "thesis proposition", and they also lack the summary and introduction of the research status quo. I wonder what is the difference between the author's research and previous research work? Therefore, the introduction of scientific papers must explain the background of research work and generally discuss the current situation of research problems. The discussion of the research status is not only to examine the author's possession and familiarity with the materials, but more importantly, to judge the significance and value of the research work and the credibility of the research results from the comprehensive degree and the old and new degree of the materials.
2) Citations are listed and lack of analysis and generalization. The introduction should not only reflect the breadth of the background, but also examine the author's understanding of the research background. Generally speaking, the author has no deep understanding of the problem studied. When introducing the current research situation, he often lists a large number of references, lists different practices and conclusions of different researchers, lacks the author's analysis and induction, fails to summarize the research results and existing problems, and some even list some documents that are not directly related to this research, unilaterally emphasizing the richness of information possession. Although some people think that different magazines have different requirements for the introduction of research status, from the perspective of paper writing, the purpose of introduction is to explain the significance of the thesis proposition, not to summarize the research data, although summary provides convenience for readers to find information. Therefore, we should use the author's own language to summarize the current research situation, especially the existing difficulties and shortcomings, thus leading to the theme of the paper.
3) Explain the writing background at that time.
