tikz 上的箭头

Question

到目前为止我一直在编写这个代码：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}
\begin{document}
  \begin{tikzpicture}
    \path     
      node (A) {$A$}
      (0:4cm)   node (B) {$B$}
      (-60:4cm) node (C) {$C$};
    \path[-stealth]
    (A) edge [bend right] node [left]  {}      (C)
    (C) edge              node [right] {} (A)
    (B) edge              node [right] {}      (C)
    (C) edge [bend right]             node [left] {}      (B)
    ([yshift=-2.5pt]A.east) edge node [above,yshift= 1.0ex]  {} ([yshift=-2.5pt]B.west)
    ([yshift= 2.5pt]B.west) edge node [below,yshift=-1.0ex]  {} ([yshift= 2.5pt]A.east);
    \end{tikzpicture}
\end{document}

结果如下：

但是，我需要一些划线箭头，例如从 C 到 B、从 C 到 A 以及从 A 到 B。我该如何制作它们？另外，如果可能的话，我可以在那里制作直箭头而不是弯曲的箭头吗？谢谢！

Answer 1

你可以将节点的度锚与这方法。像这样：

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

\tikzset{every node/.style={circle}, 
         strike through/.append style={
    decoration={markings, mark=at position 0.5 with {
    \draw[-] ++ (-2pt,-2pt) -- (2pt,2pt);}
  },postaction={decorate}}
}

\begin{document}
  \begin{tikzpicture}
    \path       node (A) {$A$}
      (0:4cm)   node (B) {$B$}
      (-60:4cm) node (C) {$C$};
    \path[-stealth]
      (A.315) edge [strike through] (C.105)
      (C.135) edge                  (A.285)
      (B.255) edge                  (C.45)
      (C.75)  edge [strike through] (B.225) 
      (B.165) edge                  (A.15)
      (A.345) edge [strike through] (B.195);
    \end{tikzpicture}
\end{document}

Answer 2

像这样？

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows, positioning}

\begin{document}
  \begin{tikzpicture}[
  node distance = 34mm and 17mm
                        ]
    \node (A) {$A$};
    \node (C) [below right=of A]    {$C$};
    \node (B) [above right=of C]    {$C$};
    \path[-stealth]
    (A) edge [bend right]   (C)
    (C) edge    node[sloped] {$|$}  (A)
    (B) edge [bend  left]   (C)
    (C) edge    node[sloped]  {$|$} (B)
    ([yshift=-2.5pt] A.east)    edge ([yshift=-2.5pt] B.west)
    ([yshift= 2.5pt] B.west)    edge ([yshift= 2.5pt] A.east);
    \end{tikzpicture}
\end{document}
