先看一下效果： ![](/static/images/ext/pdf.gif)mwe_index_two.pdf 再看源码： ```tex %mwe_index_two.tex \input{preamble_QQ2019.tex} \begin{document} \begin{tikzpicture}[decoration=brace] \draw [decorate,thick] (0,7pt) -- (.8cm-1pt,.8cm-1pt); \node[] (A) at (-26pt,0){$A_{km}(x)=2$}; \node[font=\scriptsize] (A1) at (3pt,5pt){$2$}; \node[font=\scriptsize] (A2) at (8pt,8pt){$2$}; \node[font=\scriptsize] (A3) at (15pt,15pt){$\iddots$}; \node[font=\scriptsize] (A4) at (23pt,18pt){$2$}; \node[font=\scriptsize] (A5) at (26pt,21pt){$x$}; \node[font=\scriptsize] (A6) at (8pt,22pt){$k$个}; \draw [decorate,thick] (27pt,26pt) -- (47pt,41pt); \node[font=\scriptsize] (B1) at (30pt,24pt){$2$}; \node[font=\scriptsize] (B2) at (34pt,28pt){$2$}; \node[font=\scriptsize] (B3) at (41pt,35pt){$\iddots$}; \node[font=\scriptsize] (B4) at (47pt,37pt){$2$}; \node[font=\scriptsize] (B5) at (33pt,40pt){$m$个}; \node at (80pt,-2pt) {,}; \draw [decorate,thick] (130pt,7pt) -- (129pt+.8cm,.8cm-1pt); \node[] (C) at (108pt,0){$B_{k}(y)=2$}; \node[font=\scriptsize] (C1) at (133pt,5pt){$2$}; \node[font=\scriptsize] (C2) at (138pt,8pt){$2$}; \node[font=\scriptsize] (C3) at (145pt,15pt){$\iddots$}; \node[font=\scriptsize] (C4) at (153pt,18pt){$2$}; \node[font=\scriptsize] (C5) at (156pt,21pt){$y$}; \node[font=\scriptsize] (C6) at (138pt,22pt){$k$个}; \node at (158pt,-2pt){.}; \end{tikzpicture} \end{document} ```
