Characteristics of preprint system
1. Accelerate the progress of scientific research: the preprint system can spread the research results to peer experts and readers more quickly so that they can evaluate and discuss them in time. This will help to speed up the progress of scientific research, improve the quality of scientific research and reduce the waste of scientific research.
2. High stability: the preprint system has a short publishing cycle and can quickly reflect the latest research results, so it is welcomed by more and more scholars and research institutions. In academic circles, preprint has become one of the recognized channels for information exchange.
3. Open and transparent process: The preprint system is very open and transparent in the process of receiving, reviewing and modifying research papers, which makes the process of evaluating the quality of papers more objective, fair and sustainable. Some institutions have also begun to publicize the evaluation contents for researchers to discuss and exchange evaluation opinions.
