allowframebreak 与特定幻灯片

Question

我正在尝试处理一张非常大的幻灯片，所以我用了allowframebreak那个框架。在这种情况下它不起作用。

我制造了一个平均能量损失：

\usetheme{Madrid} 
\let\Tiny=\tiny
\usecolortheme{whale} 
\usepackage[utf8]{inputenc}

\usefonttheme{professionalfonts}  
\usenavigationsymbolstemplate{} 
\setbeamertemplate{footline}[frame number]
\setbeamertemplate{frametitle}[default][center]
\setbeamersize{text margin left=2em,text margin right=2em}
\usepackage[export]{adjustbox}
\usepackage{graphicx}

\usetikzlibrary{shapes,arrows}

\setlength\PreviewBorder{5pt}%

\AtBeginSection[]
{
  \begin{frame}
    \frametitle{Tabla de contenidos}
    \tableofcontents[currentsection]
  \end{frame}
}
\begin{document}

\section{Metodología}

\subsection{Consideraciones termodinámicas}
\begin{frame}[allowframebreaks]{Title}  %HERE STARTS THE TROUBLE
\pagestyle{empty}
% Define block styles
\tikzstyle{block} = [rectangle, draw, fill=blue!20, 
    text width=8em, text centered, rounded corners, minimum height=3em]
\tikzstyle{line} = [draw, -latex']
\tikzstyle{cloud} = [draw, ellipse,fill=red!20,
    minimum height=2em]
\begin{tikzpicture}[node distance = 2cm, auto]
% Place nodes
\node [block] (react) {Reactantes};
\node [block, below of=react] (myc) {Generar microespecies y conformeros};
\node [block, below of=myc] (opt1) {Optimización (MOPAC)};
\node [block, below of=opt1] (solv) {Solvatación (programas)};
\node [block, below of=solv] (opt2) {Optimización (MOPAC)};
\node [block, left of=opt2, node distance=5cm] (metodo) {Revisar metodología};
\node [block, below of=opt2] (termo) {Cálculo termodinámico};
\node [block, below of=termo] (exp) {Contraste experiental};
\node [block, below of=exp] (decide) {¿Resultado aceptable?};
\node [block, below of=decide] (stop) {stop};
% Draw edges
\path [line] (react) -- (myc);
\path [line] (myc) -- (opt1);
\path [line] (opt1) -- (solv);
\path [line] (solv) -- (opt2);
\path [line] (opt2) -- (termo);
\path [line] (termo) -- (exp);
\path [line] (exp) -- (decide);
\path [line] (decide) -| node [near start] {no} (metodo);
\path [line] (decide) -- node {sí}(stop);
\path [line] (metodo) |- (myc);


\end{tikzpicture}

    \end{frame}
    \end{document}

您可以看到framebreak已激活。图片对于幻灯片来说太长了，下面是一张：

不要破坏流程图，而是以另一种方式绘制它。

我已经使用了 来tikz matrix帮tikz你完成节点定位。
