我正在尝试重现下面的燃料组件图片。我的问题是使用循环（即 \foreach）重复组件的 19 个板。有没有办法避免对所有 19 个板重复使用 \foreach 循环？基本上，我需要构建一次板，然后像附图中那样重复 19 次。提前感谢您的帮助。在此处输入图片描述

Tikz 默认包含 calc 包。这意味着您可以使用 + 和 - 等常规操作。要绘制包含的图片，我会使用类似这样的操作。

\documentclass[border={5mm}]{standalone}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[scale=1,
  default rectangle/.style={rectangle, draw=black,thin, minimum size=1cm}]
  % ----------------------------------------------------------------------------
  % fuel Assembly
  % ----------------------------------------------------------------------------
  % Water around the assembly
  \def\numRep{19}
  \def\Marg{0.1}
  \draw[blue,fill=blue](0-\Marg,0-\Marg) rectangle (15+\Marg,\numRep+\Marg);
  \foreach \Y in {1,2,...,\numRep}{
    \draw[blue,fill=green] (0,\Y-1) rectangle (15,\Y);
    \draw[blue,fill=blue] (1,\Y-1) rectangle (14,\Y-0.65);
    \draw[blue,fill=blue] (1,\Y-0.35) rectangle (14,\Y);
    \draw[blue,fill=red] (1.5,\Y-0.55) rectangle (13.5,\Y-0.45);
    %% Lines horisontal
    \foreach \Yline in {0.35,0.45,0.55,0.65} \draw[blue] (1,\Y-\Yline) -- +(13,0);
  };
  %% Lines vertical
  \foreach \Xline in {0,1,...,6} \draw[blue] (2*\Xline+1.5,0) -- +(0,\numRep);
  \draw[blue] (1,0) -- +(0,\numRep);
  \draw[blue] (14,0) -- +(0,\numRep);
\end{tikzpicture}
\end{document}
