我在课堂上有以下 LaTeX 代码memoir。我在处理两个顶部图之间的间距时遇到了问题。此外，子图标题 (a)、(b) 和 (c) 未居中。我是 LaTeX 的初学者，但我正在撰写博士论文。因此，任何快速帮助都将不胜感激。

为了在子火 a 和 b 之间获得更大的空间，您需要减少两个小页面的宽度，例如：
\begin{minipage}[b]{.45\linewidth}
根据您的需要进行更改.45（三次！a）、b）和c））。在两个小页面之间使用a\hfil来获得一个小的空间（1-0.45-0.45 = 0.1 \ linewidth）...
为了在 a/b 和子图 c 之间获得更大的空间，请更改\medskip tobigskip` 如下：
\par\bigskip % \medskip
子图全部居中。为了显示我为子图 b 和 c 添加了子标题。将子图 a 的较小子标题与它们进行比较。
