如题, 我的参考文献风格是plain \renewcommand\bibname{Reference} \bibliographystyle{plain} \bibliography{mybib} 然后直接插入一个bib档 bib档的格式如下 @article{GW12, author = "J. S. Guo and C. H. Wu", title = "On n free boundary problem for a two-species weak competition system", year = "2012", journal = "J. Dyn. Diff. Equat.", volume = "24", pages = "873–895" } 我预期的效果是 [5] J. S. Guo, C. H. Wu. On n free boundary problem for a two-species weak competition system. J. Dyn. Diff. Equat., 24:873–895, 2012. 但显示出来and的地方依然是and 如下 [5] J. S. Guo and C. H. Wu. On n free boundary problem for a two-species weak competition system. J. Dyn. Diff. Equat., 24:873–895, 2012. 请问如果希望作者之间以逗号连接, 该如何修改呢? 环境: book 编译: xelatex
