Answer 1

\documentclass{article}
\usepackage{mathtools}
\usepackage{unicode-math}
\setmathfont{XITSMath}
\begin{document}

\[
  \zeta\nearrow\underset
   {\mathclap{\displaystyle\Searrow \text{overshoot}\searrow}}
   {\Rightarrow \text{P.M.} \nearrow}
\]  

\[
\zeta\nearrow\underset
   {\mathclap{\Searrow \text{ overshoot }\searrow}}
   {\Rightarrow \text{ P.M. } \nearrow}
\]  

\[
  \zeta\nearrow
  \underset
     {\mathrlap{\displaystyle\Searrow\text{ overshoot}\searrow}}
     {\mathrlap{\Rightarrow\text{P.M.} \nearrow}} 
\]  
\end{document}

或者array

\[
  \zeta\nearrow
  \begin{array}[t]{@{}ll}
     \Rightarrow\text{P.M.} \nearrow \\
     \Searrow\text{ overshoot}\searrow
  \end {array}
\]
