我正在使用文档类svmono.cls，版本 v5.5，2009/12/17，写一本书。我在获取灰框环境生成灰色框，其边缘与外部文本的边缘对齐，并且其文本内容的边缘在框内对称对齐。
下面给出的样本文本中的灰色框说明了我的问题。样本文本 1 摘自例子.pdfSpringer 提供的文件。它显示了所需的灰色框。示例文本 2。显示了我实际得到的灰色框。它与我应该得到的有很大不同。
示例文本 1。
示例文本 2。
产生示例文本 2 的 MWE 代码如下所示。
\documentclass[graybox,envcountchap,sectrefs]{svmono}
\usepackage{mathptmx}
\usepackage{helvet}
\usepackage{courier}
\usepackage{type1cm}
\usepackage{makeidx}

\usepackage{multicol}
\usepackage[bottom]{footmisc}
\begin{document}
\setcounter{chapter}{1}
\setcounter{section}{3}
\subsection{Subsection Heading}%
In order to avoid simply listing headings of different levels we recommend
to let every heading be followed by at least a short passage of text.
Use the \LaTeX automatism for all your cross-references and citations
citations as has already been described in Sect. 1.2.
Please note that the first line of text that follows a heading is not
indented, whereas the first lines of all subsequent paragraphs are.
\begin{svgraybox}
If you want to emphasize complete paragraphs of texts we recommend to use
the newly defined Springer class option \verb|graybox| and the newly
defined environment \verb|svgraybox|. This will produce a 15 percent
screened box 'behind' your text.

答案1
类中的定义svgraybox是错误的：它将右边距设置为 24pt，结果正是您所看到的。
\documentclass[graybox,envcountchap,sectrefs]{svmono}
\usepackage{newtxtext,newtxmath}
\usepackage{makeidx}
\usepackage{graphicx}
\usepackage{multicol}
\usepackage[bottom]{footmisc}
\makeatletter
\renewenvironment{svgraybox}%
{\begin{shaded}%
\list{}{\leftmargin=\z@\rightmargin=\z@\topsep=\z@}%
\expandafter\item\parindent=\svparindent
\hskip-\listparindent}
{\endlist\end{shaded}}

我建议用newtxtext和newtxmath代替mathptmx。不过你可以用你喜欢的任何方式。
答案2
感谢@egreg 对我所提问题的回复，我已成功使用下面给出的代码获取所需的灰色框。我的灰框环境是 egreg 所建议的形式的稍微修改的形式。
\documentclass[graybox,envcountchap,sectrefs]{svmono}
\usepackage{newtxtext,newtxmath}
\usepackage{makeidx}
\usepackage{graphicx}
\usepackage{multicol}
\usepackage[bottom]{footmisc}
\makeatletter
\renewenvironment{svgraybox}
{\begin{shaded*}%
\list{}{\leftmargin=\p@\rightmargin=\p@\topsep=\p@}%
\expandafter\item\parindent=\svparindent
\hskip-\listparindent}
{\endlist\end{shaded*}}
\makeatother
\begin{document}

结果非常棒！
