我如何调整参考书目中的符号？

我怎样才能调整参考书目中的符号，使其变成 [1a]、[1b]、[1c] 等，而不是 [1]？

由于这个问题没有可用的 MWE，我现在假设article没有natbib包的类。因此，以下示例将根据请求生成引用：

    \documentclass{article}

    \RequirePackage{alphalph}% You could now use more than 26 sub-refs

    \begin{document}
    \makeatletter
    \newif\ifmbib\mbibfalse
    \def\@bibitem#1{\setcounter{mCtr}{0}%
           \stepcounter{enumiv}%
           \renewcommand\theenumiv{\arabic{enumiv}}%
           \global\mbibfalse\item[{[\theenumiv]}]%
           \xdef\bibCtr{\theenumiv}%
           \if@filesw\immediate\write\@auxout{\string\bibcite{#1}{\bibCtr}}\fi%
           \ignorespaces}
    \newcounter{mCtr}
    \def\mbibitem#1{\stepcounter{mCtr}%
           \ifnum\value{mCtr}=1\stepcounter{enumiv}\fi%
           \renewcommand\theenumiv{\arabic{enumiv}\alphalph{\value{mCtr}}}%
           \item[{[\theenumiv]}]\xdef\bibCtr{\theenumiv}%
           \if@filesw\immediate\write\@auxout{\string\bibcite{#1}{\bibCtr}}\fi%
           \global\mbibtrue\ignorespaces}
    \makeatother

    %Citations~\cite{one-a,one-b,one-c,one-d,two,three,four-a,four-b,four-c,five}.

    \begin{thebibliography}{10aa}
    \bibitem{zero} Zero. % This item was added at the end to check whether it works
    \mbibitem{one-a} One of One.
    \mbibitem{one-b} Two of One.
    \mbibitem{one-c} Three of One.
    \mbibitem{one-d} Four of One.
    \bibitem{two} Two.
    \bibitem{three} Three.
    \mbibitem{four-a} One of Four.
    \mbibitem{four-b} Two of Four.
    \mbibitem{four-c} Three of Four.
    \bibitem{five} Five.
    \end{thebibliography}

    \end{document}

注意：该命令\mbibitem{}可用于多部分引用，也\bibitem{}可用于普通引用。希望这对您有所帮助。
