认真阅读guide for author

应该写作者贡献吧，很好写

就是各作者贡献：For transparency, we encourage authors to submit an author statement file outlining their individual contributions to the paper using the relevant CRediT roles: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualization; Roles/Writing - original draft; Writing - review & editing. Authorship statements should be formatted with the names of authors first and CRediT role(s) following，

就是写各个作者的贡献，名字按作者的先后顺序分别加贡献，全部写完就好了
主要贡献的清单可以参考这个表：
