In different disciplines and paper forms, introduction and introduction have different writing norms and methods.

Although introduction and introduction are considered to be similar concepts in many cases, they may be different in different disciplines, paper forms and schools. The introduction usually emphasizes the argument, central topic and research background of the paper, while the introduction tends to give a preliminary introduction to the research and attract readers' attention. This difference is more obvious in different disciplines and different paper forms. For example, journal papers may pay more attention to the brief introduction of existing research, while master's papers may pay more attention to the purpose and significance of research. Therefore, the introduction or introduction should be used according to the specific requirements and subject characteristics, and the corresponding writing norms should be followed.
