正如 DLichti 所说,你可以使用 Ti钾Z。
\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
\begin{tikzpicture}
\draw[->] (0,0) -- (5.4,0);
\foreach \X in {0,...,3}
{\draw[thick,-latex] (\X,-0.1) node[below]{$\X$} -- ++(0,0.6) node[above]{$1$};}
\draw[thick,-latex] (4.6,-0.1) node[below]{$n-1$} -- ++(0,0.6) node[above]{$1$};
\node at (3.8,0.4) {$\cdots$};
\end{tikzpicture}
\end{document}
