章节标题后的垂直空间太多

章节标题后的垂直空间太多

在一个書類文档（由于某种原因，文章类的问题没有出现）我需要插入一个只包含图像的部分（图片库）。图像的大小和纵横比各不相同，但有些代码有助于自动调整它们的大小。根据图像的不同，部分标题后的垂直空间可能太大。我猜问题是部分标题后的空间被拉得太长，以避免页面末尾出现空白。我尝试增加标题前和“行”（如果我可以这样称呼它们）之间的垂直空间，但没有成功。

这是 MWE。如何增加标题前和行之间的垂直空间？我正在寻找一个通用的解决方案，而不是针对特定的图像组合进行定制。

提前感谢任何线索。

PS 我的实际文档是用 XeLaTex 编译的，我希望这不会影响解决方案。

给定代码的主要问题是底部图片不适合并被移动到下一页。

\raggedbottom环境持续时间的问题center，\clearpage最后以 结尾。

我对代码做了一些小改动：\setbox0=\hbox应该是\sbox0；而不是\hspace{1pt}使用\linebreak[0]，因此不会插入额外的空格，但是仍然允许在每个图像后换行。
