\documentclass{article}
\usepackage[margin=6cm]{geometry}
\usepackage{graphicx}
\newcommand\mysymbol
{\ensuremath{\stackrel{(\mathsf{lin})}{\longrightarrow_{(1)}}}}
\begin{document}
This is an example of what happens and what I want.
I want this: \mysymbol\ to be inline but not to
change the vertical line spacing. However, with
\verb|\smash| I get $\smash{\mysymbol}$, which is
not what I want. I want to change the symbol so it
fits in a line, not to change the line so it
superposes the symbol with another line. For example,
\verb|\scalebox{1}[0.6]{\mysymbol}| almost works, but
looks awful: \scalebox{1}[0.6]{\mysymbol}, and also
changes the symbol. The most important would be not
to change the shape of the \verb|\longrightarrow_{(1)}|.
\end{document}
有什么建议吗？

虽然很严格，但似乎有效：
\documentclass{article}
\usepackage[margin=6cm]{geometry}
\usepackage{amsmath}
\newcommand{\linto}[1]{%
\overset{\scriptscriptstyle\smash{(\mathsf{lin})}\vphantom{x}}{\longrightarrow_{(#1)}}%
}
\begin{document}
\lineskip=30pt % would kick in if lines have to be spread
This is an example of what happens and what I want.
I want this: $\linto{1}$ to be inline but not to
change the vertical line spacing.

$\linto{1}$
\end{document}
设置为高\lineskip是为了表明线条必须放大。如果没有，\smash我们会得到
所以我们看到\smash参数\lineskip没有起作用。
