Research articles and review articles are two common but distinct forms of academic writing, each with its own specific purpose, structure, and writing methods. Understanding the main differences between them is very important for both academic research and writing.

Research articles focus on reporting and discussing original research. Their main characteristics include:

-Originality: Research articles report the author's own experimental research, data sets, case studies, or theoretical analysis. These studies are usually new findings or new theories that have not yet been published.

-Data and Methodology: Research articles detail the research design, experimental methods, data collection, and analysis process. This allows other researchers to evaluate the reliability of the research and potentially replicate the experiments.

-Structure: Such articles usually follow a fixed structure, including sections such as abstract, introduction, materials and methods, results, discussion, and conclusions.

-Purpose: The purpose of a research article is to expand the field of knowledge and provide new research results, data, or theories.

Review articles are reviews and analyses of existing research literature in a certain field or topic. The main features of review articles include:

-Review and evaluation: Review articles do not report new experimental research, but summarize, synthesize and evaluate existing research in a certain field to clarify the current research status and future research directions.

-Extensive references: Such articles usually cite a large number of related studies to support the author's analysis and conclusions, with the aim of providing readers with a comprehensive perspective on the field.

-Structural flexibility: The structure of review articles is relatively flexible, but they usually include an introduction, a main body (which may be organized by topic, time or method), and a conclusion section.

-Purpose: The purpose of a review article is to provide a comprehensive understanding of a research field, point out trends, problems and gaps in research, and sometimes provide practical suggestions or future research directions.

In general, both research articles and review articles are crucial to the development of academic fields, but they serve different purposes, content and forms. Research articles focus on presenting new research results, while review articles focus on integrating and evaluating existing knowledge.
