并发章节标题和段落之间的垂直间距 (parskip) 不同

Question

我正在尝试删除章节标题之间的间距，但保留段落与章节标题之间的间距。

即使我将titlespacing前后设置为*0，仍然会有间距——在 的情况下间距会大得多\section。

我尝试了很多方法，设置得比较接近titlespacing{\<eachone>}{*0}{-5.8pt}，但还不完整，而且有很多问题。删除第一个段落和部分的垂直空间仍然比预期的多。

以下是我所拥有的：

对最新编辑的评论：

为了回应克拉克先生不喜欢\vskips 的规定，这些 s 已被成功删除。此外，所有间距都是通过titlesec包发出的，现在以 为单位指定\baselineskip，这应该为字体大小的更改提供更大的灵活性。这次编辑中有几个重大变化。首先，将 titlesec 格式从“display”更改为“hang”，这取得了很大的成就。然而， 的问题\lineskiplimit被证明是决定性的。Jeff\boxedsection创建的命令的大小不接近 的偶数倍\baselineskip，因此 LaTeX 不断添加一行来纠正一个可察觉的问题。将 line-skip-limit 设置为更负的值解决了这个问题。它允许我仅使用参数titlesec来实现结果，而无需任何 vspaces。

尽管如此，仍然存在粘合问题，我在其中一条评论中提到了这一点。我基本上可以通过将其设置\parskip为 0 并\textfloatsep使其无法增长来解决这个问题（我不确定我是否正确使用了该命令）。但是，在刷新的节标题上进行超级缩放仍然偶尔会感觉到一些粘合间隙。也许有另一个粘合参数可以提供帮助。

对早期编辑的评论：

针对可能不需要为刷新的子节和子子节标题使用单独命令的评论，我已经解决了该问题，但有一个条件。该方法通过计算\par在更高级别的节调用之后发出了多少个 s 来工作。它首先假设您有一个刷新标题的子*节。然后它开始计数\pars。一旦达到临界数字，它就会得出结论，您已将文本添加到节中，并将标题更改\sub*section为下一个较低标题级别。因此，用户在向节中添加文本的方式必须保持一致。目前，触发器设置为以下结构

\section{name}
<blank line>
text
<blank line>
\subsection{name}
<blank line>
text
<blank line>
\subsubsection{name}

或用于平齐标题

\section{name}
<blank line>
\subsection{name}
<blank line>
\subsubsection{name}

因此，仍然需要用户一致地输入其章节标题。并且由于 texexchange 会从列表中挤出空行的功能，正文中所需的空行不会显示在下面的列表中。
