以下是对此进行解释的 MWE：
\documentclass{article}
\newcommand{\scmacro}{{\sc macro}}
\begin{document}
why is there no space after \scmacro even though there is space in the document?
\end{document}
答案1
使用\scmacro\或\scmacro{}或\textsc{macro}并替换\sc为\scshape
\documentclass{article}
\newcommand{\scmacro}{{\scshape macro}}
\begin{document}
why is there no space after \scmacro\ or \scmacro{} or \textsc{macro} even though there is space in the document?
\end{document}
答案2
您需要{}在命令后面添加以确保生成的文档中有一个空格。
\documentclass{article}
\newcommand{\scmacro}{{\sc macro}}
\begin{document}
why is there no space after \scmacro{} even though there is space in the document?
\end{document}
输出：
