我正在使用带有 natbib 的 APA6 包，我注意到我的一些 bib 条目有垂直空格。我认为这与条目末尾有一个特别长的“单词”（例如 URL 或 doi）有关。
它看起来是这样的：
以下是 MWE：

我可以告诉它添加换行符或者其他内容吗？
答案1
如果不需要反向引用，则apacite.sty类加载的包会错误地定义。\PrintBackRefs
确实，它将其定义为与相同\@gobble，但生成的文件中条目的结尾.bbl就像
\APACjournalVolNumPages{Journal of Economic Psychology}{25}{5}{565--580}.
\newblock
\begin{APACrefDOI} \doi{10.1016/S0167-4870(03)00064-3} \end{APACrefDOI}
\PrintBackRefs{\CurrentBib}
这就是问题：二此处可以看到空格，从最后两个行尾开始，\par自动提供的空格只会删除一个。如果最后一个单词的结尾非常靠近右边缘，则这样的空格可以“转到下一行”，从而创建一个新行。
您可以通过添加来解决问题
\makeatletter
\AtBeginDocument{%
\@ifpackageloaded{backref}{}{\renewcommand{\PrintBackRefs}[1]{\@bsphack\@esphack}}%
}
\makeatother
到文档序言中。这是在 LaTeX 中制作命令的标准方法透明的如果它不执行任何操作并且可以在前面加上空格。
