我在 LaTeX 中遇到了一个奇怪的布局问题，由于某种原因，浮动元素可以清楚地适合一页，分布在两页上，即使使用较大的 vspace。
附图是以下代码的编译结果：
\begin{figure}[ht]
\centering
\includegraphics[width=.85\textwidth]{baseline_sensor2}
\caption{Test ID S2.1 - sensor 2}
\end{figure}
\vspace{-5cm}
\begin{figure}[ht]
\centering
\includegraphics[width=.85\textwidth]{baseline_sensor3}
\caption{Test ID S2.1 - sensor 3}
\end{figure}
我在使用此模板时曾多次遇到此问题。奇怪的是，如果我设法将尺寸缩小到足以将浮动元素集中在一页上，我仍然可以在同一页上添加一些文本，而不会弄乱布局。即使尺寸缩小与页面不适合的内容相差 1%。
这是我的序言。

抱歉，代码片段太大了，但我不知道它哪里出了问题。
答案1
浮动元素的默认位置（通常也是最佳位置）是[tbp]（顶部、底部、页面）。您可以使用宏来更改浮动元素在页面上的位置。这些宏与括号中的默认值一起，是
将其更改为\setcounter：
topnumber（2）页面顶部的最大浮动数量
bottomnumber（1）页面底部的最大浮动数量
totalnumber（3）文本页面上的最大浮动数量
dbltopnumber（2）类似于topnumber双列浮点数
更改以下内容\renewcommand：
\topfraction（0.7）页面中为顶部浮动保留的最大比例
\bottomfraction（0.3）页面底部浮动的最大分数
\textfraction（0.2）页面中必须包含文本的最小部分
\dbltopfraction（0.7）类似于\topfraction双列浮点数
\floatpagefraction（0.5）浮动页面的最小分数，必须有浮动
\dblfloatpagefraction（0.5）类似于\floatpagefraction双列浮点数
还有一些用于控制浮点数周围间距的宏。
课程memoir文档（< texdoc memoir）在其部分中提供了更多详细信息10.4 LaTeX 放置浮点数的位置。
调整上述参数，直到获得适合您的布局。
