如何将箭头样式应用于弯曲箭头？

我有一个箭头样式，它适用于直箭头。该样式的唯一目的是放大箭头，因此如果有更简单的方法可以做到这一点，请告诉我。无论如何，当我将样式应用于弯曲箭头时，不会渲染任何箭头。提供的 MWE 显示带有默认箭头的弯曲箭头，但我非常希望以某种方式应用我的箭头样式。

\documentclass{article}
\usepackage{tikz}
\usepackage{float}

\usetikzlibrary{calc,shapes.multipart,chains,arrows,decorations.markings}

\begin{document}
\begin{figure}[H]
  \centering
  \begin{tikzpicture}[list/.style={rectangle split, rectangle split parts=2,
    draw, rectangle split horizontal, thick, minimum
    height=1cm}, >=stealth, start chain]
    
    \tikzstyle{arrow} = [decoration={markings,mark=at position 1 with
    {\arrow[scale=2,>=stealth]{>}}},postaction={decorate}]

    \node[list,on chain] (A) {$A_1$};
    \node[list,on chain] (B) {$A_2$};
    \node[list,on chain] (C) {$A_3$};
    \node[list,on chain] (D) {$A_4$};
    \node[list,on chain] (E) {$A_5$};
    \node[on chain] (F) {NULL};
    \draw[arrow] let \p1 = (A.two), \p2 = (A.center) in (\x1,\y2) -- (B);
    \draw[arrow, dashed] let \p1 = (B.two), \p2 = (B.center) in (\x1,\y2) -- (C);
    
    %%%%---I would like the arrowhead style applied here---%%%%
    \draw[->,>=stealth, thick] let \p1 = (B.two), \p2 = (B.center) in (\x1,\y2) to [bend left=60] (D.one west);
    \draw[arrow] let \p1 = (C.two), \p2 = (C.center) in (\x1,\y2) -- (D);
    \draw[arrow] let \p1 = (D.two), \p2 = (D.center) in (\x1,\y2) -- (E);
    \draw[arrow] let \p1 = (E.two), \p2 = (E.center) in (\x1,\y2) -- (F);
  \end{tikzpicture}
\end{figure}
\end{document}

像这样？

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta,    % <---
                bending,
                chains,
                shapes.multipart}

\begin{document}
    \begin{tikzpicture}[
every edge/.style = {draw, -{Stealth[angle=30:7pt, bend]}}, % <---
 start chain = going right,
 list/.style = {rectangle split, rectangle split parts=2,
               rectangle split horizontal, 
               rectangle split empty part width=1.5em, 
               draw, thick, minimum height=1cm, 
               on chain}, 
               ]

\node [on chain] (F) {NULL};

\draw[semithick]
        (B.two north |- B.two east) edge[bend left=45] (D.west);
    \end{tikzpicture}

编辑： 添加了箭头尺寸的详细信息。如果箭头长度相同，则所有箭头都相同：

  • 如何确定箭头尺寸在章节中描述16.3.1 大小在里面TikZ & PGF 手册，第 194-197 页。它是您tikz安装的一部分，或者您可以在 CTAN 中找到它（使用谷歌找到它）。

  • 如果箭头是弯曲的，则将箭头头与弯曲线对齐，选项bend和flex。它们的用法在章节中描述16.3.8 弯曲和屈曲，第 202-204 页。

  • 对于这两个功能，您需要加载库arrows.meta和bending
