First: simple repetition
This level of paper is the worst, there is no new method and viewpoint, that is, it repeats other people's research topics and needs in-depth writing.
Second: there is no new discovery.
No new insights and discoveries, no important improvements. For the revision of this kind of paper, it is necessary to explore experimental research, improve technology and experiment repeatedly.
Third: Unconfirmed theory
This level of paper has been able to discuss the content of the paper completely, but it can't demonstrate the theme of the paper, and the materials or skills used in this way are meaningless. It is suggested to delete these useless parts and find better discussion content to demonstrate the theme of the paper.
Fourth: No breakthrough.
It adds new contents to the original theory, but there is no major key breakthrough. This level of paper is actually a good paper, but it is still not enough to deliver high-scoring journals, especially foreign SCI papers. Without a key breakthrough, the innovation of the paper is insufficient.
Fifth: the most suitable medical papers for publication.
Discover new laws that have not been discovered by predecessors and put forward new theories, which have been affirmed by academic circles. There was a great invention in technology, and the old theory was overthrown by facts. Put forward new guiding ideology and methods. The last level of the paper is the basic requirement for a high-quality paper. As long as these contents are met, domestic journals and SCI papers will be included.
