Tikz Chains 的最左边节点的一侧为粗体

大家早上好。这实际上是我第一次在这里写文章，所以感谢所有回复的人。我正在写我的本科论文，目前我被困在画一台图灵机上。我想做的事情是这样的：

在此处输入图片描述

除了我希望第一个节点的左侧（仅左侧，而不是所有 4 条边）非常厚之外。到目前为止，我所做的如下：

\begin{tikzpicture}
\edef\turingtapesize{0.7cm}
\tikzstyle{tape}=[draw,minimum size=\turingtapesize]
\tikzset{
    leftmostnode/.style={
        draw,minimum size=\turingtapesize,
        append after command={% <= for the leftside line of the leftward node
            \pgfextra{%
            \begin{pgfinterruptpath}
            \begin{pgfonlayer}[foreground]
                \draw[verythick] (\tikzlastnode.south west)--(\tikzlastnode.north west);
            \end{pgfonlayer}
            \end{pgfinterruptpath}
            }
        }
    }
}

% Drawing the tape itself
\begin{scope}[start chain=0 going right,node distance=0mm]
    \node[on chain=0,tape] (b)  {0};
    \node[left=of b,leftmostnode](a){1};
    \node[on chain=0,tape] (c)  {1};
    \node[on chain=0,tape] (d)  {0};
    \node[on chain=0,tape] (e)  {1};
    \node[on chain=0,tape] (f)  {0};
    \node[on chain=0,tape] (g)  {0};
    \node[on chain=0,tape] (h)  {1};
    \node[on chain=0,tape] (i)  {1};
    \node[on chain=0,tape] (l)  {$\sqcup$};
    \node[on chain=0,tape] (l)  {$\sqcup$};
    \node[on chain=0,tape] (l)  {$\sqcup$};
\end{scope}
\end{tikzpicture}

但是我收到一个错误：

抱歉，无法找到请求的层“[”。也许您拼错了？。

\nodeleft=of b，最左边的节点{1}；

我是否也可以问你如何得到那种“电锯”般的结尾（这个词真的存在吗？）？谢谢，干杯 ;) 资料来源：1 2

编辑 根据 moospit 的建议，我解决了“厚度问题”。现在我只需要创建那条特殊的锯齿线 ;)

EDIT2 我刚刚看到你的回复。我用一种稍微不同的方法解决了这个问题。我在下面发布了整个 tikz-image 的代码；)

\begin{tikzpicture}
\edef\turingtapesize{0.7cm}
\tikzstyle{tape}=[draw,minimum size=\turingtapesize]

% Drawing the tape itself
\begin{scope}[start chain=0 going right,node distance=0mm]
    \node[on chain=0,tape]          (a)     {1}       ;
    \node[on chain=0,tape]          (b)     {0}       ;
    \node[on chain=0,tape]          (c)     {1}       ;
    \node[on chain=0,tape]          (d)     {0}       ;
    \node[on chain=0,tape]          (e)     {1}       ;
    \node[on chain=0,tape]          (f)     {0}       ;
    \node[on chain=0,tape]          (g)     {0}       ;
    \node[on chain=0,tape]          (h)     {1}       ;
    \node[on chain=0,tape]          (i)     {1}       ;
    \node[on chain=0,tape]          (l)     {$\sqcup$};
    \node[on chain=0,tape]          (l)     {$\sqcup$};
    \node[on chain=0,tape]          (l)     {$\sqcup$};
    \node[on chain=0,tape,draw=none](m)     {}        ;
    \node[on chain=0,tape,draw=none](n)     {$\ldots$};

% Coordinates
    \coordinate(snake1) at ($ (l.north east)!0.5cm!(m.north east) $);
    \coordinate(snake2) at ($ (l.south east)!.5cm!(m.south east) $) ;

    \draw [-] (l.north east) -- (snake1);
    \draw [-] (l.south east) -- (snake2);
    \draw[snake=snake,
        segment amplitude=.4mm,
            segment length=1.75mm,
        line after snake=0mm] (snake1) -- (snake2);
\end{scope}

    \draw[ultra thick] (a.south west) -- (a.north west)                   ;
    \node[draw,above=0.75cm of e,minimum size=\turingtapesize] (Q) {$q_3$};
    \draw[-latex] (Q) -- (e)                                              ;     
\end{tikzpicture}

\begin{tikzpicture}
  \tikzset{tape/.style={minimum size=.7cm, draw}}
  \begin{scope}[start chain=0 going right, node distance=0mm]
   \foreach \x [count=\i] in {1,0,1,0,1,0,0,1,1,$\sqcup$,$\sqcup$,$\sqcup$} {
    \ifnum\i=12 % if last node reset outer sep to 0pt
      \node [on chain=0, tape, outer sep=0pt] (n\i) {\x};
      \draw (n\i.north east) -- ++(.1,0) decorate [decoration={zigzag, segment length=.12cm, amplitude=.02cm}] {-- ($(n\i.south east)+(+.1,0)$)} -- (n\i.south east) -- cycle;
     \else
      \node [on chain=0, tape] (n\i) {\x};
     \fi
     \ifnum\i=1 % if first node draw a thick line at the left
      \draw [line width=.1cm] (n\i.north west) -- (n\i.south west);
     \fi
   }
   \node [right=.25cm of n12] {$\cdots$};
   \node [tape, above left=.25cm and 1cm of n1] (q3) {$q_3$};
   \draw [>=latex, ->] (q3) -| (n5);
  \end{scope}
 \end{tikzpicture}

最终结果如下： 在此处输入图片描述

答案1

那么如何使用你的tape节点样式a并在链代码后添加它：

\draw [very thick] (a.south west) -- (a.north west);

或者

\draw [line width=.1cm] (a.south west) -- (a.north west);

这样，您就可以在节点上方添加一条额外的线a。

编辑：更新链末端的锯齿节点 (MWE)

这里还有一些关于 zigzag-node 的信息。我zigzag在下面描述的路径的一部分上使用了 -decoration。只需zigzag segment length根据您的需要调整和振幅即可。

注意将outer sep链节点的设置为0，否则曲折路径将与north east和south east坐标产生一些偏移。

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

\usetikzlibrary{decorations.pathmorphing, calc}

\begin{document}
 \begin{tikzpicture}
  \node [draw, outer sep=0pt] (n) {n};
  \draw (n.north east) -- ++(.1,0) decorate [decoration={zigzag, segment length=.12cm, amplitude=.02cm}] {-- ($(n.south east)+(+.1,0)$)} -- (n.south east) -- cycle;
 \end{tikzpicture}
\end{document}

仅剩一个编辑：无法抗拒 ;)。稍微重写一下代码，让链可以扩展到更多元素：

如果您还有更多问题，请直接提问。如果您愿意，可以轻松更改zigzag一些内容。snakes

\documentclass[tikz, border=5mm]{standalone}
\usetikzlibrary{calc, chains, decorations.pathmorphing}

    \ifnum\i=11 % if last node reset outer sep to 0pt
      \node [on chain=0, tape, outer sep=0pt] (n\i) {\x};
