What does it mean to quote 0 in the paper search?
1. Repeated citation of 0 actually means that the citation rate of cited documents in repeated reports is 0%.
Why do you want to copy the reference 0?
1. Cited documents are not marked: The simple understanding is that the duplicate checking system will automatically detect the quoted parts when checking duplicates, which requires everyone to mark the cited documents. If the cited documents are not marked, the duplicate checking system will not be able to detect the citation rate, and of course there will be repeated citations of 0.
2. The source of references is not in the database: when the references cited in the paper are not stored in the database of the duplicate checking system used by everyone, the duplicate checking system cannot detect the citation rate.
3. The citation content is too short: when the citation content is too short, the paper duplicate checking system cannot match the citation content, and the citation rate will be zero.
4. The quoted content is modified: if the quoted text content is modified, the quoted content can't match the literature source of the paper duplicate checking system, so the quoted rate can't be detected naturally.
5. Incorrect reference format: If the reference format is not standardized, the paper detection system may mark the reference in red and calculate the repetition rate, and the citation rate cannot be detected at this time.
