我正在尝试调整标题之间没有文字的\chapter& \section、\section&\subsection和\subsection&之间的间距，以使副标题之间的间距相同。我需要在所有标题上方留三倍空格 ( )，在所有文本之前留两倍空格 ( )。（这些尺寸也可以是s，它们只需保持一致即可）\subsubsection3ex2ex\baselineskip
在我的类文件中，我用来titlesec完全控制标题。但是，如果不添加负数，我似乎无法获得正确的间距\vspace：
\titlespacing{\chapter}

\titlespacing{\section}

我想避免的是这样的：
\chapter{\uppercase{Chapter 1}}
\vspace{-2ex} % Space between chapter and section with no text (Try to avoid this)
\section{Section 1}
\vspace{-1ex} % Space between section & subsection with no text (Try to avoid this)
\subsection{Subsection 1}
对阵
\chapter{\uppercase{Chapter 1}}
\lipsum[66]
\section{Section 1}
\lipsum[66]
\subsection{Subsection 1}
有人知道我可以在哪里进行此调整吗？
答案1
我是这样定义标题间距的（从某处复制并调整到我满意为止），结果是，无论是文本还是章节标题在章节标题上方都无关紧要。但我不想弄乱我的论文，所以请自己尝试是否可以更改加号和减号参数。我在文档中没有找到有关其工作原理的任何解释。
