先看一下效果：
<a href="https://static.latexstudio.net/data/attach/201911/8c19e105303b519.pdf" target="_blank">mwe_index_two.pdf</a>
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){.};

这样的制作也是可以了, 有个其他的方式, 不过要进行一大堆的代码去调整角度和显示, 还不如 TiKZ 来得快.
其他用户看看有没有更好的方法.
