Literature review should not be a repetition, listing and general introduction of existing literature, but a critical analysis and comment on the advantages and disadvantages and contributions of previous studies. Therefore, the literature review should contain the dual meanings of comprehensive refining and analytical review. Therefore, literature review has three characteristics: comprehensiveness, criticism and advancement.
Several writing methods of literature review
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. For example, 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) Influencing factors A: For example, in the article "Preparation, Modification and Application of Collagen-Chitosan Edible Composite Film", the "Factors Affecting the Properties of Edible Film" and previous research results were discussed one by one.
2) The factors influenced by A or the results caused by A: For example, the article "The Influence of New Media Development on College Students' Behavior and the Countermeasures of Education Guidance" respectively expounds the influence of new media on college students' ideological morality, values education and thinking mode.
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 1: Literature review of the article "Extraction, structural analysis and anti-colon cancer effect of Morchella esculenta polysaccharide" introduced the extraction, separation and purification, structure and biological activity of Morchella esculenta polysaccharide. Example 2: The article "Progress in the Application of Mass Spectrometry in the Research of Traditional Chinese Medicine" introduces the technical characteristics and technical 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 1: 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 2: 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.
