我使用以下定义来生成argmax运算符：
\DeclareMathOperator*{\argmax}{\arg\!\max}
但是问题是当我在某个部分使用它时，由于argmin下一行下方的书面参数以异常距离出现，因此存在某些文本，以保持与 argmin 下的参数的距离。但是当我使用\frac例如这次时，比例会自行调整以不与下一行重叠。我如何更改上述命令以使其表现得像frac？
例子：
\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator*{\argmax}{\arg\!\max}
\begin{document}
This is a test. This is a test. $\argmax\limits_{x}{x^2}$ This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test.
\end{document}

相反的是：
\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator*{\argmax}{\arg\!\max}
\begin{document}
This is a test. This is a test. $\frac{x}{x^2}$ This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test.
\end{document}

据我了解，您想手动校正垂直间距，使其更接近此值，而无需操作员。恐怕结果不会很漂亮。此类解决方案的一个例子如下（手动选择垂直间距）：
\documentclass{article}
\usepackage{amsmath}
%\DeclareMathOperator*{\argmax}{\arg\!\max}
\DeclareMathOperator*{\argmax}{argmax}
\begin{document}
This is a test. This is a test. $\argmax\limits_{\raise3pt\hbox{$\scriptstyle x$}}{x^2}$ \vspace{-5pt}
This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. This is a test.
\end{document}
