Literature can be divided into first-class literature, second-class literature and third-class literature according to its content, nature and processing mode. Primary literature refers to the original literature created on the basis of the author's own research results, such as periodical papers, research reports, patent specifications, conference papers, etc.
One-off literature refers to the literature formed by the author directly based on the research object or scientific research results and combined with his own opinions. This kind of literature usually only analyzes and expounds the problems in this research field in depth, and does not involve other related issues. Disposable files include the following contents:
A research paper is an academic paper aimed at exploring, describing, experimenting or verifying a certain problem in a specific research field. This kind of literature usually includes introduction, methods, results and discussions, aiming at providing the latest knowledge in the research field.
A report is a detailed description of a specific problem or project, including problem analysis, solutions, implementation plans, etc. Reports are usually issued by government agencies, consulting companies, enterprises, etc. , designed to provide decision makers with comprehensive information about the problem.
Technical specification is a detailed technical description of a specific product or system, including functions, performance, operational requirements, etc. Such documents are usually published by manufacturers or developers to provide comprehensive information about products or systems.
A newspaper or periodical article is a detailed description and analysis of current events, problems or viewpoints. Such documents are usually published by news organizations to provide comprehensive information about current events.
A patent is a detailed description of an invention or innovation, including technical details, implementation, etc. Patents aim to protect the rights and interests of inventions or innovations and provide information about technological development.
One-off documents are an important part of academic research, which deeply analyzes and expounds problems or research in specific fields. However, because they only focus on specific areas, there may be some limitations. In academic research, it is usually necessary to combine various types of documents, including first-class documents and second-class documents, in order to obtain more comprehensive information and analysis.
Conference papers refer to academic papers read or published at academic conferences, aiming at exchanging and displaying the latest research results. This kind of literature usually includes introduction, methods, results and discussions, aiming at providing the latest knowledge in the research field.
