In the field of scientific research, SCI(ScienceCitationIndex) is an important index to measure the quality of academic papers. However, even if the paper is accepted after minor repairs, it may be rejected in the final review stage. The following are some common reasons that may lead to minor revisions of SCI papers:

1. The research method is not rigorous: reviewers may question the research method of the paper and think it is not rigorous enough or has loopholes. This may include experimental design, data collection and analysis.

2. Unreasonable explanation of the results: If the results of the paper are inconsistent with the existing research, or the author's explanation of the results is not reasonable enough, the reviewers may be skeptical.

3. The structure of the paper is chaotic: the structure of the paper should be clear and definite, and there should be a logical relationship between the parts. If the structure of the paper is chaotic, it may leave a bad impression on the reviewers.

4. Insufficient or inaccurate references: References are an important part of the paper, reflecting the author's understanding and mastery of relevant research. If the references are insufficient or inaccurate, it may affect the quality of the paper.

5. Unclear language expression: the language of the paper should be clear, accurate and concise. If the language of the paper is unclear, it may bring trouble to the reviewers.

6. Repeated publication: If the content of the paper is repeated with the author's previously published papers, or the difference between it and the previously published papers is not fully explained, it may be considered as repeated publication.

7. Ethical issues: If the paper involves human experiments or animal experiments, it is necessary to ensure that all experiments comply with ethical regulations. Otherwise, the paper may be rejected because of ethical issues.

8. Data fraud: This is the most serious problem. If the data is found to be false, the paper will not only be rejected, but also the author's academic reputation will be seriously damaged.
