当作者列表不同时，引用显示“a”“b”，例如 (2018a) 和 (2018b)

Question

因此，问题在于，即使作者列表不同，如果第一作者相同，它也会添加“a”和“b”，例如 2018a 和 2018b。如果文章类型为 @techreport 而不是 @article，则似乎不会发生此问题。

这是完整的代码。

Answer 1

这是一个有趣的效果。它可以在以下降低的 MWE 中重现

\documentclass{article}

\usepackage[style=authoryear,
  maxbibnames=99,
  maxcitenames=1,
  uniquename=false,
  uniquelist=false,
  natbib=true]{biblatex}

\begin{filecontents}{\jobname.bib}
@article{last2018test1,
  title   = {test1},
  author  = {Last, First and Lasttwo, Firsttwo},
  journal = {Journal1},
  year    = {2018},
}
@article{last2018test2,
  title   = {test2},
  author  = {Last, First and Lasthi, Firsthi and Laster, Firster},
  journal = {Journal2},
  volume  = {30},
  number  = {2},
  pages   = {47--60},
  year    = {2018},
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}
\citet*{last2018test1}

\citet*{last2018test2}

\citet{last2018test1}

\citet{last2018test2}

\printbibliography
\end{document}

显然，“a”和“b”对于唯一标识条目来说不是必需的。

这里的“问题”是带星号的natbib兼容性命令的使用\citet*。在natbib兼容模式下，无论输出内容是什么，都会产生（在说话时）\citet*的输出，但包含完整的作者列表。\citet\textcitebiblatexmaxcitenames

将其与 'normal' 的输出进行比较\citet，即

这里的“a”和“b”是必需的，以便能够将两个引用与参考书目条目唯一匹配。

---

根据所需的输出，您可以做几件事。

我可能会安排一些东西，这样我就不必一直使用。这可以通过删除和选项\citet*来实现。maxcitenamesuniquelist

\documentclass{article}

\usepackage[style=authoryear,
  maxbibnames=99,
  uniquelist=false,
  natbib=true]{biblatex}

\begin{filecontents}{\jobname.bib}
@article{last2018test1,
  title   = {test1},
  author  = {Last, First and Lasttwo, Firsttwo},
  journal = {Journal1},
  year    = {2018},
}
@article{last2018test2,
  title   = {test2},
  author  = {Last, First and Lasthi, Firsthi and Laster, Firster},
  journal = {Journal2},
  volume  = {30},
  number  = {2},
  pages   = {47--60},
  year    = {2018},
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}
\citet*{last2018test1}

\citet*{last2018test2}

\citet{last2018test1}

\citet{last2018test2}

\printbibliography
\end{document}

但如果您想要不同的输出，也许您需要稍微不同的设置。
