我试图避免SciTePress.sty样式引入的第一段缩进。我认为问题在于\section样式内的重新定义。因为，如果我删除它，节标题后的第一段就不会缩进。
我的问题是，如何将命令的行为更改\section为“节后不缩进”？我认为我必须在代码中重新定义它，因为我无法更改给定的样式。此外，我可以在同一次重新定义中同时将节标题设为大写吗？

您应该将beforeskip(的第 4 个参数\@startsection) 设为负数。始终使用绝对值，但如果为负数，则会忽略标题后的段落文本的缩进。
\def\section{\@startsection{section}{1}{\z@}{24pt plus 2pt minus 1pt}
{12pt plus 2pt minus 1pt}{\Large\bf\raggedright}}
然后变成
\def\section{\@startsection{section}{1}{\z@}{-24pt plus -2pt minus -1pt}
{12pt plus 2pt minus 1pt}{\Large\bf\raggedright}}
这样应该就能解决问题了。当然，您可以在自己的源代码中执行此操作（在加载样式之后），然后需要用\makeatletterand将其包装起来，\makeatother因为该@符号用于宏定义中。
