1, demonstration-discussion and proof of basic scientific propositions, or theoretical analysis of new ideas, models, materials, processes, etc. In order to improve, supplement or revise them. For example, the determination of specific indicators to maintain the healthy life of rivers and the distribution of initial water rights in river basins all belong to this type. People who specialize in research write more scientific papers in this field.

2. Science and technology report-A science and technology report is a document that describes the achievements or progress of a scientific research, or the results of a technical research experiment and evaluation, or discusses the present situation and development of a scientific and technological problem. Narrative is a special case of it. The feasibility demonstration articles of professional technology, engineering schemes and research plans, and scientific and technological report papers account for the vast majority of modern scientific and technological documents. People engaged in engineering design and planning write more scientific papers in this field.

3. Discovery and invention-an article describing the background, phenomenon, essence, characteristics, movement and change law of discovered things or events and the prospect of human beings using this discovery. An article describing the efficacy, performance, characteristics, principles and conditions of use of the invented equipment, systems, tools, materials, processes, formula forms or methods. People engaged in engineering construction write more articles in this field.

4. Design and calculation-computer program design to solve some engineering problems, technical problems and management problems, computer-aided design and optimization design of some systems, engineering schemes and products, computer simulation of some processes, design or modulation and preparation of some products or materials, etc. People who are engaged in computer and other software development write more scientific papers in this field.

5. Abstract-This is a special scientific paper. The main difference between it and general scientific papers is that it does not require the original research content. Although a good abstract article often contains some new materials and new ideas that have not been published before, it requires the author to put forward the development and evolution law and trend of related professional topics in a specific period on the basis of comprehensive analysis and evaluation of existing materials.

Generally speaking, there are two ways to write it: one is to collect literature, supplemented by comments, and objectively not to comment. The other focuses on comments. Through review, observation and prospect, this paper puts forward logical and enlightening views and suggestions. People engaged in management work write more scientific papers in this field.
