在 beamer 中使用 parencite 和 biblatex 包之后有额外的空格 (

tag-icon • tag-icon beamer biblatex citing
在 beamer 中使用 parencite 和 biblatex 包之后有额外的空格 (

这是我的代码：

\documentclass[10pt]{beamer}
\usetheme{CambridgeUS}
\usepackage[backend=biber,style=ieee,citestyle=authoryear]{biblatex}

\bibliography{literature.bib}

\begin{document}
    network design\parencite{sb2016}
\end{document}

现在它会产生如下结果： 在此处输入图片描述

请注意 ( 和作者姓名之间有一个空格。

我尝试过这个：Biblatex[-chicago, authordate] 首次引用的脚注。额外的空格放在括号中但它告诉我 cite:init 未定义。

我以前从未遇到过这个问题。我甚至更新了所需的软件包，看看它是否能纠正错误。没有，它不起作用。很奇怪。

更新：bibentry

@article{sb2016,
  title={Strategic design of public bicycle sharing systems with service level constraints},
  author={Lin, Jenn-Rong and Yang, Ta-Hui},
  journal={Transportation research part E: logistics and transportation review},
  volume={47},
  number={2},
  pages={284--294},
  year={2011},
  publisher={Elsevier}
}

我正在使用 biblatex 软件包版本 3.7。和 biber 2.7。

虚假空间是由

\AtEveryCitekey{%
\ifentrytype{article}{
\clearfield{pages}%
\clearfield{volume}%
}{}
}

您需要保护（某些）行尾，以免%造成空格。请参阅行末百分号（%）有什么用？。

和

\AtEveryCitekey{%
  \ifentrytype{article}{%
    \clearfield{pages}%
    \clearfield{volume}}
  {}%
}

空格应该消失。
