如何将段落（仅在“ltxmdf”类中有效）插入到“book”类文档中？

Question

我有下一个文档（在 ltxmdf 类中），它可以完美编译（查看图像）。

我想要放入一个文档书籍类。可以吗？

我已经尝试过了，但出现 4 个错误。我该如何更改标题？

提前致谢。

\documentclass[parskip=false,11pt]{ltxmdf}
\newcommand\Loadedframemethod{default}
\usepackage[framemethod=\Loadedframemethod]{mdframed}
\mdfsetup{skipabove=\topskip,skipbelow=\topskip}
\newrobustcmd\ExampleText{%
An \textit{inhomogeneous linear} differential equation has the form
\begin{align}
L[v ] = f,
\end{align}
where $L$ is a linear differential operator, $v$ is
the dependent variable, and $f$ is a given non-zero
function of the independent variables alone.
}

只需要对序言进行少量修改：

\documentclass[parskip=false,11pt]{book}
    \usepackage[framemethod=tikz]{mdframed}
\mdfsetup{skipabove=\topskip,skipbelow=\topskip}
    \usepackage{mathtools}

\newcommand\ExampleText{%
    An \textit{inhomogeneous linear} differential equation has the form
    \begin{align}
    L[v ] = f,
    \end{align}
    where $L$ is a linear differential operator, $v$ is
    the dependent variable, and $f$ is a given non-zero
    function of the independent variables alone.
                        }

代码的其他部分与你的 MWE 中的相同。得到的定理图像也相同。
