It is suggested that we should fully realize the arduousness and importance of the preface. Because every researcher is familiar with his research technical scheme, technical route, experimental process and technical achievements. He is generally aware of it and easy to show it. In the preface, it is difficult to generalize, summarize and analyze the work of others, and it is also difficult to discuss one's own views. Papers published in domestic journals generally don't pay much attention to the preface, and the preface of degree thesis is also repositioned. Therefore, in order to improve the quality and level of papers, we must think deeply on the basis of carefully referring to articles in foreign periodicals. We can write as detailed as possible first, and then simplify it as needed. Don't be simple at first, and then tinker with it later, it will be difficult to form a system.

The research background is objective and concise.

The abstract of the paper is a high summary of the significance, content and characteristics of the paper, and the abstract of about 500 words should be concise and to the point. When commenting on other people's research work, the paper must be objective and avoid causing controversy. Especially when it comes to its shortcomings, we must be cautious. When you are uncertain, don't comment casually by feeling or impression.

Outstanding features or innovations in research work.

Generally, there is no special requirement for the innovation of master's thesis, but the characteristics should always be there. That is, a problem in production or research is solved by using ready-made methods, principles and technologies, and it is also considered to have practical characteristics.

We should try our best to show readers the characteristics or innovations of research work. In order to show the importance of the thesis, some graduate students list a lot of features and innovations, whether they are features or innovations, while others are not at all.

In fact, as a master's thesis, as long as the topic has certain significance and workload, it can be completed independently, there are no mistakes, it meets the basic requirements and has characteristics, and it is good to have two or three innovations or characteristics. So, don't deliberately look for so many features and innovations. Even if there is a real innovation, it is ok. The key is to clarify the real characteristics and innovation.

Master's thesis should use diagrams, tables, formulas and data as much as possible to express meaning, explain principles and schemes, and help readers understand the content.

Reference materials should be updated.

The documents listed in the reference should be marked in the paper as far as possible. On the one hand, it respects the achievements of others; On the other hand, it reflects L's rich reading literature and well-founded theory. Some references may be quoted indirectly, so it is not necessary to mark them.

Pay attention to references and try to choose the latest published articles and works. Some graduate students don't pay attention to this problem, and many of the references they choose are articles and works decades ago.

With the rapid development of science and technology, we should always master and understand the latest knowledge. Many scientists are used to reading references first when reading papers. If the references are too old, it means that the knowledge they have mastered and referenced is not up-to-date, so they may doubt whether the research content of the paper is novel.
