🌳🗡❀老师@u38442 指出，下面的公式排版是优雅的，并且有宏包实现之：
After searching on TSE and following this link， we can copy the following MWE:
\documentclass{article}
\usepackage{amsmath}
\usepackage{adjustbox}% http://ctan.org/pkg/adjustbox
\begin{document}
\begin{multline*}
f(x)=a_0+a_1x+a_2x^2+\clipbox{-2 0 5 0}{$\overbrace{a_3x^3+a_4x^4+\cdots+a_{i-1}x^{i-1}+\hspace{1em}}^{\text{some text}}$} \\[\jot]
\clipbox{100 0 -2 0}{$\overbrace{\phantom{\hspace{10em}}a_ix^i+a_{i+1}x^{i+1}}$}+\cdots+a_{n-1}x^{n-1}
\end{multline*}
\end{document}
How to tune the above MWE?
