If the editor sends a reason for rejection, please take it seriously, analyze the reasons for rejection, and then decide whether to revise the paper before submitting it or to submit it to other journals. Sometimes, the rejection is not the problem of the paper, but the lack of queue and the tight layout.
Rejection means that the author's formal contribution to the editorial department of sci-tech periodicals has not been accepted by the editorial department. The method of manuscript rejection is stipulated in the contract of periodical manuscripts, which generally includes full-text rejection, partial rejection (no rejection of drawings), no rejection of manuscripts, etc., and rejection by post office or e-mail.
