TikZ 中图片的对齐

我在用 TikZ 绘制几张图片时遇到了一些麻烦。它对两张相邻的图片进行了不同的对齐，如下所示：

在此处输入图片描述

另外，我怎样才能使“and”垂直居中？

如果这是重复的问题，我深表歉意。它以前肯定出现过，但我没有看到。这是代码。任何其他评论和建议都值得赞赏，因为我刚刚学习 TikZ。

编辑：我推测对齐方式不同是因为右侧底部包含标签。但我仍然想知道如何让“and”垂直居中。

一个简单的解决方案是使用baseline=25mm选项：

\documentclass[12pt]{article}
\usepackage{tikz}
\usetikzlibrary{calc,shapes}
\usepackage{mathrsfs}

\begin{document}
\begin{center}
\begin{tikzpicture}[baseline=25mm]
\coordinate                 (a0) at (0,0);
\coordinate                 (a1) at (5,5);
\coordinate[label=left:$g$] (a2) at (2.5,3.5);
\fill (a2) circle (2pt);
\coordinate[label=above:$X$](a3) at (2.5,5);
\coordinate[label=left:$f$] (a4) at (2.5,2.25);
\fill (a4) circle (2pt);
\coordinate[label=above:$\varepsilon$] (a5) at (3.5,1.5);
\fill (a5) circle (2pt);
\coordinate[label=below:$Y$](a6) at (1.5,0);
\coordinate                 (a8) at (4.35,2.5);
\coordinate[label=above:$L$](a9) at (4.5,5);
\draw (a0) rectangle (a1);
\draw plot [smooth] coordinates {(a4) (a5) (a8) (a9)};
\draw (a3) -- (a2) -- (a4) -- (a6);
\coordinate[label=$\mathbf{1}$]     (1) at (1,3);
\coordinate[label=$\mathscr{D}$]    (D) at (3.4,3.4);
 \coordinate[label=$\mathscr{C}$]   (C) at (3.78,.5);
\end{tikzpicture}
\hfil and\hfil
\begin{tikzpicture}[baseline=25mm]
    \draw (0,0)   rectangle (5,3);
    \draw (0,3.5) rectangle (5,5);
    \draw (2.5, 5) -- (2.5, 3.5);
    \draw (4, 5)   -- (4, 3.5);
\coordinate[label=above:$X$] (X) at (2.5,5);
\coordinate[label=above:$L$] (L) at (4.0,5);  
    \draw (2.5, 3) -- (2.5, 1.8) -- (1,0);
    \draw plot [smooth] coordinates {(2.5, 1.8) (3.4, 1) (4, 1.8) (4, 3)};
\coordinate[label=below:$\varepsilon$] (epsilon) at (3.4, 1);
    \fill (epsilon) circle (2pt);
\coordinate[label=left:$g$] (g) at (2.5, 4);
  \fill (g) circle (2pt);
\coordinate[label=left:$f$] (f) at (2.5, 1.8);
  \fill (f) circle (2pt);
\end{tikzpicture}
    \end{center}
\end{document}

在代码中，我还修复了一些小问题，正如 Alenanno 在他的评论中提到的那样，纠正了坐标名称的重复。通过这个修正，我得到了：

这就是你要找的吗？
