更改为“et al”时出现“未定义的控制序列”

2024-5-25 • tag-icon

我对 latex 还很陌生，尝试用 Rmarkdown 和 tinytex 写我的学士论文（我从教授那里得到了一个模板）。我的问题是，我无法将参考书目中的德语 ua 改为拉丁语“et al.”。我试过\DefineBibliographyStrings{ngerman}{andothers={et\addabbrvspace al\adddot}}在序言中这样做，但编译失败，出现错误“！未定义的控制序列。”

先感谢您！

编辑：我的 YAML-Header 看起来像这样

---
geometry: "a4paper,top=2cm,bottom=2cm,left=3.5cm,right=2cm"
fontsize: 12pt
linestretch: 1.5
automark: yes
indent: true
toc: false
classoption:
  - DIV=calc
  - headsepline=true
KOMAoptions:
  - headings=standardclasses
  - DIV=last  
table_caption: true
figure_caption: true
includes:  
  in_header: figure_placement.tex 
link-citations: yes
knit: "bookdown::render_book"
output:
  bookdown::pdf_book:
    includes:
      in_header: tex/praeambel.tex
    keep_tex: yes
    latex_engine: pdflatex
citation_package: biblatex

使用 Rmarkdown 时，时间安排可能很重要。在处理前言文件时，通过 YAML 文件中的选项加载的包可能可用，也可能不可用。在这种情况下，将命令包装biblatex在中会有所帮助，这样它们在加载\AtEndPremable时就会执行。biblatex

替换\DefineBibliographyStrings{ngerman}{andothers={et\addabbrvspace al\adddot}}为

\AtEndPreamble{%
  \DefineBibliographyStrings{ngerman}{andothers={et\addabbrvspace al\adddot}}%
}
