1. research field: different subjects have different research objects and methods, so the content of the paper will be different. For example, biology papers may focus on genes, cells and biological processes, while physics papers may involve quantum mechanics, relativity and other fields.
2. Research methods: Different research methods in different fields will affect the structure of the paper. For example, psychological papers usually adopt experimental methods and observation methods, while economic papers may adopt statistical methods and case analysis methods.
3. Paper structure: Different disciplines have different paper structures. For example, chemical papers usually follow the naming rules and structure of IUPAC (International Union of Pure and Applied Chemistry), while humanities and social sciences papers may include abstracts, introductions, literature reviews, methods, results, discussions and conclusions.
4. Paper objectives: Different fields have different paper objectives. For example, the main goal of medical papers is to discover new treatments and drugs, while engineering papers may focus on technological innovation and application.
5. Writing style: There are also differences in writing styles of papers in different disciplines. For example, computer science papers usually use concise and clear language, while literary papers may pay more attention to rhetoric and depict delicate emotions.
6. citation and format: the citation and format requirements of papers in different fields may also be different. For example, social science papers usually follow the citation norms of APA (American Psychological Association) or MLA (Modern Language Association), while mathematics and physics papers follow specific citation formats.
In short, papers in different scientific research fields are different in content, structure, objectives and writing style, which embodies the characteristics and requirements of each field.
