需要有关 TikZ 中箭头的帮助

Question

我需要一个看起来像这样的箭头图：

我为此编写的乳胶代码是：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes,arrows.meta,positioning}

\begin{document}
    
    \begin{tikzpicture}
        \centering
        
        \node[ellipse,draw,minimum size=2cm,text centered,text width=0.15\textwidth] (a) {Fuzzy regular open};
        \node[ellipse,draw,minimum size=2cm] at (6,6) (b) {Fuzzy open};
        \node[ellipse,draw,minimum size=2cm] at (12,0) (c) {Fuzzy $\gamma^*$-open};
        \node[ellipse,draw,minimum size=2cm,text centered,text width=0.15\textwidth] at (9,-6) (d) {Fuzzy semi $\delta$-open};
        \node[ellipse,draw,minimum size=2cm] at (3,-6) (e) {Fuzzy $\delta$-open};
        
        \draw[->] (a)--(b);
        %\draw[->] (b)--(a);
        \draw[<->] (b)--(c);
        \draw[<->] (c)--(d);
        \draw[->] (e)--(d);
        %\draw[->] (d)--(e);
        \draw[->] (e)--(a);
        %\draw[->] (a)--(e);
        \draw[<->] (a)--(c);
        \draw[->] (e)--(b);
        %\draw[->] (b)--(e);
        \draw[<->] (a)--(d);
        \draw[<->] (c)--(e);
        \draw[<->] (a)--(d);
        
    \end{tikzpicture}
    
\end{document}

这是输出：

节点没问题，但我在箭头方面遇到了困难。我还希望箭头比现在大一点。请帮我修复箭头，使它们像第一张图片中的箭头一样。

虽然这不是最终的图片，但我认为它包含了您想要的所有元素。

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes,arrows.meta,positioning}

\begin{document}
    
\begin{tikzpicture}[
    >={Straight Barb[scale=3]},    % <--- added
    tick/.style={draw,minimum width=0pt,minimum height=3ex,inner sep=0pt,sloped},  % <--- added
]
    \centering
    
    \node[ellipse,draw,minimum size=2cm,text centered,text width=0.15\textwidth] (a) {Fuzzy regular open};
    \node[ellipse,draw,minimum size=2cm] at (6,6) (b) {Fuzzy open};
    \node[ellipse,draw,minimum size=2cm] at (12,0) (c) {Fuzzy $\gamma^*$-open};
    \node[ellipse,draw,minimum size=2cm,text centered,text width=0.15\textwidth] at (9,-6) (d) {Fuzzy semi $\delta$-open};
    \node[ellipse,draw,minimum size=2cm] at (3,-6) (e) {Fuzzy $\delta$-open};
    
    \draw[->] (a.80)--(b.200);  % <--- modified
    \draw[->] (b.230)-- node[pos=0.5,tick]{} (a.40);  % <--- modified
    \draw[<->] (b)--(c);
    \draw[<->] (c)--(d);
    \draw[->] (e)--(d);
    %\draw[->] (d)--(e);
    \draw[->] (e)--(a);
    %\draw[->] (a)--(e);
    \draw[<->] (a)--(c);
    \draw[->] (e)--(b);
    %\draw[->] (b)--(e);
    \draw[<->] (a)--(d);
    \draw[<->] (c)--(e);
    \draw[<->] (a)--(d);
    
\end{tikzpicture}
    
\end{document}

使用信息 Ti钾Z 库arrows.meta（用于箭头）、quotes（用于标记线）和shapes.geometric（用于节点定位），节点边的通用样式，其中有两条来自节点的边，它们的开始和停止由试验定义：

\documentclass[border=3.141592]{standalone}
%\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                quotes,
                shapes.geometric}

\begin{document}
    \begin{tikzpicture}[
       > = {Straight Barb[line width=0.6pt, angle=60:3pt 4]}, 
E/.style = {ellipse, draw, semithick,
            text width=5.5em, inner ysep=2pt, inner xsep=-3pt,
            align=center, font=\small\linespread{0.84}\selectfont},
every edge quotes/.append style = {font=\footnotesize,
                                   anchor=center,sloped}
                        ]
\node (P)   [regular polygon,
             regular polygon sides=5,
             minimum size =66mm] {};
%
\node[E] (e1) at (P.corner 1) {Fuzzy\\ open};
\node[E] (e2) at (P.corner 2) {Fuzzy regular open};
\node[E] (e3) at (P.corner 3) {Fuzzy\\ $\delta$-open};
\node[E] (e4) at (P.corner 4) {Fuzzy semi $\delta$-open}; % d
\node[E] (e5) at (P.corner 5) {Fuzzy $\gamma^*$-open}; % c
%
\path[<->]   
        (e1) edge["$\mid$"] (e5)
        (e1.310) edge["$\mid$"] (e4)
        (e2) edge["$\mid$"] (e5)
        (e4) edge["$\mid$"] (e5);
\path[->]
        (e1.210) edge["$\mid$"] (e2.50)
        (e1.255) edge["$\mid$"] (e3.80)
        (e2.260) edge["$\mid$"] (e3.135)
        (e3.7)   edge (e4.173);
\path[<-]
        (e1.230) edge (e2.30)
        (e1.280) edge (e3.55)
        (e2.285) edge (e3.115)
        (e3.353) edge["$\mid$"] (e4.187);
    \end{tikzpicture}
\end{document}
