Tips: ChinaXiv supports the online dissemination of the latest research achievements at home and abroad, guarantees the authors' online first publishing rights, and provides the fastest academic information exchange. These papers have undergone preliminary political and academic review, without strict peer review, but after publication, this platform implements open post evaluation. Encourage authors to publish their results in preprint editions in academic journals, as they do not constitute duplicate publications. The preprint platform is also an important source of information for readers to access the latest scientific research progress. Authors and readers should adhere to a pragmatic attitude and a serious and responsible spirit, and jointly create a new type of academic exchange system for preprint.
