The strict requirement of periodical publication date and the standard of judging periodical weight are usually subject to the strict requirement of periodical publication date. At present, journals adopt the test standard of academic misconduct, so we can also check our published journal papers with academic defects. In fact, many journals have their own standards when publishing journals. Without telling you the standard, I suggest that the repetition rate of papers in various journals should be controlled at around 15% and not more than 20%. At present, the review of papers published in periodicals is very strict. If you quote a lot of other people's literature in the journal, it is likely to be rejected by the journal reviewers, and you may not necessarily contribute, so the journal papers should be original.
After understanding the criteria for duplicate checking of journal papers, the authors basically check the duplicates themselves in the academic paper duplicate checking system, although the publication time of some magazines will be stricter. If the magazine tells you in advance what the duplicate checking standard is, you can use the duplicate checking system to check the first draft, then modify it, and then finalize your own paper for duplicate checking to prevent academic misconduct, and then lower your duplicate checking standard to the requirements of the magazine. Plagiarism is not allowed, and the same manuscript cannot be published many times. This phenomenon of multiple submissions is also prohibited.
