Details are as follows:
A theme: determine the theme of the paper, and search, read and mine literature information around this theme.
A map (mind map): around the theme of the paper, on the basis of reading the literature, make an outline of the literature review, and then fill in the content step by step according to the outline.

Although the requirements of each school are different, the structure of graduation thesis literature review is usually:
Introduction/Research Background-Subject/Research Status-Summary/Research Purpose and Significance-Research Content-References
(1) Introduction/Background
The introduction need not be too long, just explain the research background.
Realistic materials: statistical data, examples of production and life, policies and regulations, etc.
Theoretical data: the focus, emphasis and bibliometric analysis of basic theoretical research.
Example 1: "study on the effect of tangshen recipe on improving lipid metabolism disorder in C57BLKS/J db/db mice and its related mechanism", pointing out the research background and leading to the theme with statistical data.
Excerpt "The incidence of diabetes in China has been on the rise in recent decades, from less than 1% in 1980 to 9.7% in 2007, and the death toll caused by diabetes in 20 100 was10.3 million, which was 1990. According to the latest epidemiological survey, the prevalence rates of diabetes and prediabetes among people over 8 years old in China are about 1 1.6% (about 1. 1.39 million people) and 50 1% (about 49,340 people) Studies have also shown that overweight and obesity and abnormal blood lipid levels are high risk factors for diabetes. "
Example 2: Study on the preparation and properties of natural polymer-based multifunctional hemostatic composite dressing. Starting from practical problems, the current research difficulties and key points are pointed out.
However, due to the morphology or characteristics of materials, the hemostatic mechanism of many materials has not been carefully and quantitatively studied (such as oxidized regenerated cellulose). ). This makes the subsequent process improvement of materials extremely difficult. It is an important problem to be solved urgently that how to change the morphology of the materials, what special detection methods are used, and how to study the hemostatic mechanism of oxidized regenerated cellulose and collagen materials from multiple scales. "
(2) Theme
The main part mainly talks about the research status quo. For children's shoes that are still in their infancy, we can sort out and summarize the literature according to the following ideas.
1. time series method
Analyze the historical development of the theme and discuss it in chronological order, which is suitable for the development and evolution of the subject.
Example 3: In the article "Development Course, Mode Evolution and Lessons of China-Industry-University-Research Linkage", the "Development Course of China-Industry-University-Research Linkage" is divided into three time stages, and then the scenarios, characteristics and linkage modes of each stage are discussed respectively.
2. Causality analysis method
Analyze the factors that affect the development of the object, or the factors affected by the object, list every possible reason/result, and discuss them separately, which is suitable for the research of technical process optimization and problem analysis.
1) factors affecting a
Example 4: The article "Preparation, Modification and Application of Collagen-Chitosan Edible Composite Film" discusses the "factors affecting the properties of edible film" and previous research results one by one.
2) factors influenced by a or results caused by a.
Example 5: The article "The Influence of New Media Development on College Students' Behavior and Countermeasures for Education Guidance" specifically expounds the influence of new media on college students' ideological morality, values education and way of thinking.
3. "Structure-activity relationship" method
It is suitable for discussing the structure, function and application of a substance, or the structure, function and application of a device, or the explanation, function and application of a theory.
Example 6: Literature Review The article "Extraction, structural analysis and anti-colon cancer effect of polysaccharide from Morchella esculenta submerged fermentation" introduced the extraction, separation and purification, structure and biological activity of Morchella esculenta polysaccharide.
Example 7: The article "Progress in the Application of Mass Spectrometry in the Research of Traditional Chinese Medicine" introduces the technical characteristics and classification of mass spectrometry and its application in the identification of components, metabonomics and metabolic kinetics of traditional Chinese medicine.
4. Current situation and countermeasures
It is suitable for analyzing the origin, development status, characteristics, existing problems and solutions of a phenomenon.
Example 8: The article "The Present Situation, Problems and Suggestions of the Development of Bicycle Enjoyment" is discussed according to the present situation, problems and suggestions of the development of bicycle enjoyment.
Example 9: Research on service innovation of university library in the era of fragmented reading This paper probes into the characteristics, reasons, opportunities and challenges brought by fragmented reading to university library service, and gives some suggestions from four aspects of innovative service concept, mode, content and quality evaluation system.
5. Division of labor and combination method
There are two research objects in this paper, substance 1- substance 2, phenomenon 1- phenomenon 2, substance/instrument-disease, substance-equipment, substance-method and equipment-theoretical method. You can discuss the situation and problems of the two research objects separately, and then discuss the (possible) situation and advantages of the combination of the two.
Example 10: Comment on the article "Application of high-resolution MRI in cerebrovascular assessment". Firstly, the main indexes of cerebral blood flow and its traditional evaluation methods are discussed, then the characteristics and application of a new technology-high resolution magnetic resonance wall imaging are introduced. Finally, it is concluded that high resolution magnetic resonance wall imaging can be used to evaluate cerebral vascular wall.
Example 1 1: A review of the article "Preparation, structure and properties of gelatin-chitosan-based biodegradable films", in which the characteristics of gelatin and chitosan are discussed respectively, and then the research progress of gelatin-chitosan-based composites is introduced.
Example 12: Study on preparation technology and quality standard of Shen Ge Royal Jelly Capsule. Firstly, the research progress of anti-aging is discussed, then the components and pharmacological effects of ginseng, pueraria lobata and royal jelly are discussed, and then the two parts are combined to lead to their own research content.
6. Process narrative method
According to the workflow and process steps of the object, the research situation of each step is discussed in turn.
Example 13: The summary part of the article "Study on the extraction, concentration and spray drying process of Salvia miltiorrhiza and analysis of related parameters" discusses the extraction, concentration and drying process and parameters in turn.
(III) Summary/Research Purpose and Significance
As mentioned above, the summary cannot be just "comprehensive" without "description". We must put forward our own views, ideas, research ideas and prospects on the basis of summarizing and combing previous studies.
Especially as a part of the opening report and graduation thesis, we should put forward the existing problems in the summary part, that is, the problems to be solved by our own research, so as to transition to our own research purpose, significance and content.
There is no difference between the above different writing ideas. You can choose your own ideas according to the topic selection and literature collection, and further subdivide each idea and framework.
In the process of writing, you can also arrange and combine these ideas and nest them with each other.
By refining the writing framework and filling in the content, it is easy to get a literature review.
