放置在 tikz 矩形中的方程元素的移位

我想定义新命令来最小化以下代码：

 \documentclass{beamer}
 \usepackage{mathtools,tikz,lmodern, xparse}
\usetikzlibrary{shapes.geometric, arrows, matrix, positioning,  shapes.callouts,shadows,shapes,chains, shapes.misc}
\tikzset{>=stealth}

\usepackage{amsmath} %For align environement
\usepackage{color}% to define the next colors
\definecolor{airforceblue}{rgb}{0.36, 0.54, 0.66}
\definecolor{alizarin}{rgb}{0.82, 0.1, 0.26}
\definecolor{white}{rgb}{1.0, 1.0, 1.0}
\definecolor{blue(munsell)}{rgb}{0.0, 0.5, 0.69}

\begin{document}


 \begin{frame}{Quantum corrections to gauge interactions}
 \begin{align*} 
 F(\Phi)= \only<1>{\begin{tikzpicture}[remember picture, note/.style={rounded rectangle, fill=blue}]\node[rounded rectangle, draw, fill=blue!20](Alpha){$\alpha$}; 
 \end{tikzpicture}}\only<2->{\alpha} X
 +\only<2>{\begin{tikzpicture}[remember picture, note/.style={rounded rectangle, fill=blue}]\node[rounded rectangle, draw, fill=blue!20](gPhi){$g(\Phi)$};
 \end{tikzpicture}}\only<1,3->{g(\Phi)}
\end{align*}
 \begin{tikzpicture}[remember picture, 
 note/.style={rectangle        callout,rounded corners, fill=blue}]
\only<1>{\node [note=blue!50, opacity=.5, overlay,
callout absolute pointer={(Alpha.south)}] at (4,-0.3) {CommentI};}
\only<2>{\node [note=blue!50, opacity=.5, overlay,
callout absolute pointer={(gPhi.south)}] at (7,-0.3) {CommentII};}
 \end{tikzpicture}

\end{frame} 

\end{document}

我试过 ：

  \documentclass{beamer}
  \usepackage{mathtools,tikz,lmodern, xparse}
  \usetikzlibrary{shapes.geometric, arrows, matrix, positioning, shapes.callouts,shadows,shapes,chains, shapes.misc}
 \tikzset{>=stealth}

\usepackage{amsmath} %For align environement
\usepackage{color}% to define the next colors
\definecolor{airforceblue}{rgb}{0.36, 0.54, 0.66}
\definecolor{alizarin}{rgb}{0.82, 0.1, 0.26}
\definecolor{white}{rgb}{1.0, 1.0, 1.0}
\definecolor{blue(munsell)}{rgb}{0.0, 0.5, 0.69}

\NewDocumentCommand{\rect}{ m m m m m}{\begin{tikzpicture}[remember picture, note/.style={rounded rectangle,rounded corners}]
\node[rounded rectangle, draw, fill=#1!#2](#3){#4};\end{tikzpicture}}

\newcommand{\mycallout}[9]{\begin{tikzpicture}[remember picture, note/.style={rectangle callout,rounded corners}]
\node [note=#3!#4, opacity=.5, overlay,
callout absolute pointer={(#5)}] at (#7,#8) {#9};
\end{tikzpicture}}

\begin{document}


 \begin{frame}{Quantum corrections to gauge interactions}
 \begin{align*} 
 F(\Phi)= \only<1>{\rect{blue}{20}{Alpha}{$\alpha$}}\only<2->{\alpha} X
 +\only<2>{\rect{blue}{20}{gPhi}{$g(\Phi)$}}\only<1,3->{g(\Phi)}
\end{align*}

\only<1>{\mycallout{blue}{50}{Alpha.south}{4}{0.3} {CommentI}}
\only<2>{\mycallout{blue}{50}{gPhi.south}{7}{-0.3} {CommentII}} 
\end{frame}     
\end{document}

但它给了我错误File ended while scanning use of \frame.。我想要修复的另一个问题是由于 tikz 框导致的$\alpha$和的偏移。${g(\Phi)}$

答案1

我设法修复并优化了你的第一个例子，看看在这之后你是否仍然需要在第二个例子中定义新命令：

    \documentclass{beamer}
        \usepackage{mathtools,tikz,lmodern, xparse}
    \usetikzlibrary{%arrows, chains, matrix, 
                    positioning, 
                    %shadows,
                    shapes, shapes.callouts,
                    %shapes.geometric,
                    %shapes.misc
                    }

    \tikzset{>=stealth,
             note/.style={rectangle callout, 
                          callout absolute pointer={#1},
                          rounded corners, draw, fill=blue!20,
                          %, fill opacity=.5  %<-- is this necessary?
                          }
             }

    \usepackage{amsmath} %For align environement
    %\definecolor{airforceblue}{rgb}{0.36, 0.54, 0.66}
    %\definecolor{alizarin}{rgb}{0.82, 0.1, 0.26}
    %\definecolor{white}{rgb}{1.0, 1.0, 1.0}
    %\definecolor{blue(munsell)}{rgb}{0.0, 0.5, 0.69}

\newcommand{\rect}[2]{%
        \tikz[remember picture,baseline=-0.5ex]
        \node[name=#1,rounded corners, draw, fill=blue!20] {#2};}

    \begin{document}
    \begin{frame}{Quantum corrections to gauge interactions}
        \begin{align*}
 F(\Phi)=   \only<1>{\rect{Alpha}{$\alpha$}}
            \only<2->{\alpha} X +
            \only<2>{\rect{gPhi}{$g(\Phi)$};}
            \only<3->{g(\Phi)}
        \end{align*}

        \begin{tikzpicture}[remember picture,overlay,
                            node distance=7mm and 1mm]
    \only<1>{\node [note=(Alpha.south),
                    below left= of Alpha] 
                    {Comment I};}
    \only<2>{\node [note=(gPhi.south),
                    below right= of gPhi] 
                    {Comment II};}
        \end{tikzpicture}
    \end{frame}
    \end{document}

编辑（1）：我添加了newcommand输入方程式的功能rect。

编辑（2）： newcommand用于输入mycall方程式的注释：

\newcommand{\mycallout}[4]{%
    \tikz[remember picture,overlay,
          node distance=7mm and 1mm]{%
          \node [note=(#1.#2),
                below #3= of #1]
                {#4};}     }

并根据您的情况如下使用：

\only<1>{\mycallout{Alpha}{south}{left}{Comment I}}
\only<2>{\mycallout{gPhi}{south}{right}{Comment II}}

正如我所见，它并没有使代码变得更短。
