🔗 引用与参考文献交叉核对（\cite ↔ .bib、[1] ↔ 文献表）Citation Cross-check (\cite vs .bib, [1] vs reference list)
投稿前核对正文引用和参考文献是否一一对应：LaTeX 模式找出 \cite 了但 .bib 中没有的键（编译后显示 ?）、.bib 中从未引用的条目和重复键，并提示大小写或拼写相近的键；Word 模式检查 [1]、[2–5] 顺序编码引用是否超出文献表、是否有未引用条目、首次引用是否按顺序编号，以及 (Smith et al., 2020) 作者-年份引用是否都能在文献表中找到。Before submission, check that in-text citations and the reference list match. LaTeX mode finds \cite keys missing from the .bib (the “?” after compiling), entries never cited and duplicate keys, and suggests near-miss keys. Word mode checks [1]/[2–5] numeric citations against the list, uncited entries and first-citation order, and that every (Smith et al., 2020) author–year citation has a matching entry.
LaTeX 模式识别 \cite、\citep、\citet、\citeauthor、\citeyear、\parencite、\textcite、\autocite、\footcite、\nocite 等命令（含可选参数和多个键），会忽略 % 注释中的引用。顺序编码模式检查 [1]、[2–5]、[3,7] 是否都在参考文献表中、是否有从未引用的条目、首次引用是否按顺序（IEEE、GB/T 7714 顺序编码制要求）。作者-年份模式按“第一作者姓 + 年份”匹配（Smith et al., 2020a 等）。全部在浏览器本地完成。LaTeX mode understands \cite, \citep, \citet, \citeauthor, \citeyear, \parencite, \textcite, \autocite, \footcite, \nocite and more (optional arguments, multiple keys) and ignores citations inside % comments. Numbered mode checks that every [1], [2–5], [3,7] exists in the list, finds uncited entries, and checks first-citation order (required by IEEE and Vancouver). Author–year mode matches on first-author surname + year (Smith et al., 2020a). Everything runs locally.

如何使用「引用与参考文献交叉核对（\cite ↔ .bib、[1] ↔ 文献表）」？How do I use the Citation Cross-check (\cite vs .bib, [1] vs reference list)?
选择模式后，左侧粘贴正文（.tex 可以多个文件一起打开），右侧粘贴 .bib 或参考文献表，结果实时更新：红色是必须修改的问题，黄色是建议检查的项目。Choose a mode, paste the manuscript on the left (several .tex files can be opened together) and the .bib or reference list on the right. Results update live: red must be fixed, yellow is worth a look.
为什么 PDF 里显示 [?]？Why does my PDF show [?]
LaTeX 找不到 \cite 的键时会显示问号，常见原因是键拼写或大小写不一致（如 Ba2016 与 ba2016）、条目不在 .bib 中，或没有重新运行 BibTeX/Biber。本工具会列出这些键并给出最接近的正确键。LaTeX prints ? when a \cite key is not found — usually a spelling or case mismatch (Ba2016 vs ba2016), a missing entry, or BibTeX/Biber not re-run. This tool lists those keys and the closest existing key.
顺序编码制为什么要按首次出现排序？Why must numeric citations be in order?
IEEE、Vancouver、GB/T 7714 顺序编码制要求参考文献按在正文中首次被引用的先后编号，第一次出现 [5] 之前应已出现过 [1]–[4]。IEEE, Vancouver and GB/T 7714 numeric styles number references by first appearance, so [1]–[4] must appear before the first [5].
