改变乳胶样式的箭头

Question

是的，我知道有一个arrowhead选项，但由于某种原因它不起作用。还有其他选择吗？

\documentclass{article}
\usepackage[
  a4paper,
  margin=15mm,
  bindingoffset=2mm,
  heightrounded,
]{geometry}
\usepackage{mathptmx}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes.arrows,arrows.meta}


\begin{document}

\begin{flushleft}

\begin{tikzpicture}
\draw[blue, ultra thick] (0,0) -- (4,0);
\draw[blue, ultra thick] (0,5) -- (4,5);

\node at (-1, 0) {\huge{$E_0$}};
\node at (-1, 5) {\huge{$E_1$}};

\foreach \x in {0,1,2,3} 
      \draw[red, very thick] (6,\x) -- (10,\x);

\foreach \x in {0,0.2,0.4,0.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\foreach \x in {1,1.2,1.4,1.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\foreach \x in {2,2.2,2.4,2.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\foreach \x in {5,6,7,8} 
      \draw[red, very thick] (6,\x) -- (10,\x);

\foreach \x in {5,5.2,5.4,5.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\foreach \x in {6,6.2,6.4,6.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\foreach \x in {7,7.2,7.4,7.6} 
      \draw[black, thick] (12,\x) -- (16,\x);

\draw[latex-latex] (2,0) -- (2,5) node[midway,fill=white]{\huge{$\Delta E_1$}};
               
\end{tikzpicture}
\end{flushleft}
\end{document}

我不知道这是否是你感兴趣的，但你可以使用隐形箭，

\documentclass{article}

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

\begin{document}

\begin{figure}
\begin{tikzpicture}
    \draw[very thick, {Stealth[length=3mm, width=2.5mm]}-{Stealth[length=3mm, width=8mm]}] (0,-1)--(10,-1);
\end{tikzpicture}
\end{figure}

\end{document}

得到以下结果
