From submission to employment, a paper has to go through three stages: preliminary examination, review and final examination. Every level has the possibility of being eliminated, but the probability of being eliminated is different. There is no uniform standard for the probability of rejection of papers after preliminary examination. Some journals will be higher, while others will be lower, perhaps around 40%-50% or higher.
Re-examination is a peer expert review link, and experts in the same field generally review the professionalism of the paper, such as the accuracy and authenticity of experimental data, the rationality of experimental results, and the scientific research methods. This is the most difficult level in the process of paper review, and it is also a link to evaluate the quality level of papers. Whether it is severity, time or rejection probability, it will be stricter, longer and higher than the first instance.
After peer experts finish, they will feed back the opinions or suggestions of peer review to the editorial department of the journal. The editorial department of the journal synthesizes the opinions of many experts and makes the final processing result. Once a paper is rejected, it contributes to the probability of rejection, but it is hard to say clearly what the probability of rejection is, only that it is not low.
Journals that publish papers include Chinese general journals, English general journals, domestic cores and international cores. Different levels of requirements for papers have different probability of rejection. Relatively speaking, the higher the level or influence of a journal, the higher the probability of rejection. Generally speaking, you can use the rejection probability of about 40%-50% as a reference.
