使用 tikz 图:
\documentclass{article}
\usepackage{tikz}
\usepackage{siunitx}
\begin{document}
\begin{tikzpicture}[>=latex,scale=1]
\node[blue] at (-180:4) (t) {\bf TEXT};
\coordinate (a) at (220:2);
\coordinate (b) at (90:2);
\coordinate (c) at (0:2);
\draw[->,thick,black] (0,0) -- (a) node[left] {$\vec{i}$};
\draw[->,thick,black] (0,0) -- (b) node[right] {$\vec{k}$};
\draw[->,thick,black] (0,0) -- (c) node[right] {$\vec{j}$};
\end{tikzpicture}
\end{document}
