我尝试在使用 tex4ht 将 LaTex 转换为 html 时生成方程式。如果我将环境放在 minipage 中，则会出现错误。
文件是
\documentclass{article}
\usepackage{amsmath}
\begin{document}
After a time $t$, the ground state $\ket{g}$ and the excited state $\ket{e}$ will each have accumulated a phase that is proportional to their energies:
\medskip
\noindent
\fbox{\begin{minipage}{0.98\textwidth}
\begin{align}
\ket{\psi(0)} \to \ket{\psi(t)} = \frac{e^{-iE_1 t/\hbar}}{\sqrt{2}} \ket{g} + \frac{e^{-iE_2 t/\hbar}}{\sqrt{2}} \ket{e}\, .
\end{align}
\end{minipage}}
We can take out the factor $e^{-iE_1 t/\hbar}$ as a global unobservable phase, and obtain
\begin{align}\label{eq:atomequator}
\ket{\psi(t)} = \frac{1}{\sqrt{2}} \ket{g} + \frac{e^{-i(E_2 - E_1)t/\hbar}}{\sqrt{2}} \ket{e}\, .
\end{align}
\end{document}
当我使用命令编译上述文件时，htlatex test.tex myconfig.cfg它给出以下错误消息
! Argument of \verbatim@ has an extra }.
<inserted text>
\par
l.13 \end{minipage}}
myconfig.cfg 包含以下代码行

如果我在 minigpage 中输入多行方程式，它会给出相同类型的错误消息
请指导

问题是\verbatim在命令参数中使用了 (\begin{align}扩展为\verbatim)。我宁愿使用框架数学的自定义环境，它可以在 中进行配置tex4ht。
修改后的 TeX 文件：
\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{braket}
\usepackage{mdframed}
\newenvironment{framedmath}{\mdframed}{\endmdframed}
\begin{document}
After a time $t$, the ground state $\ket{g}$ and the excited state $\ket{e}$ will each have accumulated a phase that is proportional to their energies:
\medskip
\noindent
\begin{framedmath}
\begin{align}
\ket{\psi(0)} \to \ket{\psi(t)} = \frac{{e}^{{-iE}_{1} t/\hbar}}{\sqrt{2}} \ket{g} + \frac{e^{-iE_2 t/\hbar}}{\sqrt{2}} \ket{e}\, .
\end{align}
\end{framedmath}
We can take out the factor $e^{-iE_1 t/\hbar}$ as a global unobservable phase, and obtain
\begin{align}\label{eq:atomequator}
\ket{\psi(t)} = \frac{1}{\sqrt{2}} \ket{g} + \frac{e^{-i(E_2 - E_1)t/\hbar}}{\sqrt{2}} \ket{e}\, .
\end{align}
\end{document}
环境mdframed是作为环境的替代来使用的，\fbox并且用于环境minipage的定义中。framedmath
如果您需要mathjax-latex-4ht.sty来自helpers4ht捆：
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml,html5}
\Configure{@HEAD}{\HCode{
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
TeX: {
Macros: {
\unexpanded{ ket: ['{\\left|\#1\\right\\rangle}',1]}
},
equationNumbers: { autoNumber: "AMS" }
}
});
</script>
}}
\begin{document}
\renewenvironment{framedmath}{\ifvmode\IgnorePar\fi\EndP\NoFonts\HCode{<div class="fbox">}\verbatim}{\endverbatim\HCode{</div>}\EndNoFonts\par}
\EndPreamble
framedmath环境的重新定义使用\verbatim命令来打印其内容不变。如果您不想使用修改后的配置文件，则可以将此定义与原始配置文件一起使用。
\renewenvironment{framedmath}{\ifvmode\IgnorePar\fi\EndP\NoFonts\HCode{<div class="fbox">}\verbatim}{\endverbatim\HCode{</div>}\EndNoFonts\par}
结果如下：
