我在 Overleaf 中准备了一篇论文。在 Overleaf 或本地计算机的 TexStudio 中，PDF 文档中的参考文献编号没有任何问题。但是，当我将 TeX 文档上传到期刊时，在创建期刊的 PDF 校样后，参考文献编号显示为“问号”（“？”）。我无法解决这个问题。当我查看日志文件时，发现存在与引用相关的错误，例如：
软件包 natbib 警告：第 7 页上的引用‘xxx’在输入行 212 上未定义。
软件包 natbib 警告：第 10 页上的引用“yyy”在输入行 286 上未定义。
总之，Overleaf 中没有任何问题，但该期刊的在线 pdf 证明没有包括带有编号的参考文献，例如 (1) (2)，而是显示为问号（“????”）。
我在等你的帮助。谢谢。我还添加了我的所有 .bib 文件：
