A periodical paper, or an academic research paper, is an article that presents original research and is operated by the author. The research methods may be different, such as experiments, surveys, interviews, etc. However, the author must collect and analyze the original data and draw conclusions according to the analysis results.

Research papers usually have a fixed format. First, there is an "introduction" to talk about the existing literature review of the research topic, and then there is a detailed chapter "Materials and Methods". The author must clearly describe the method of obtaining data and the way of analysis here. The more detailed the information provided here, the better, so that other researchers can copy the research and then have a "result" to explain the contribution of the research results to the present or future research.
