文本周围有两个大括号

tag-icon • tag-icon brackets
文本周围有两个大括号

又回来了！目前正在尝试双括号：其中单词 {para}{para} 单词都在一行上。我正在尝试玩弄代码。但我似乎无法让它工作。这是我的尝试。任何建议都非常感谢！

这是我之前在这里提出的类似问题，该问题的答案如下： 文本周围的大括号

想要实现的目标示例：

答案1

使用完全不同的方法：

\documentclass{article}
\usepackage{scalerel}
\parskip 1em
\begin{document}

\def\mytext{blah blah blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah}

\def\lftmk{\{}
\def\rgtmk{\}}

word
\scaleleftright[2ex]{\lftmk}{\parbox{4cm}{\mytext}}{\rgtmk}
\scaleleftright[2ex]{\lftmk}{\parbox{4cm}{\mytext\mytext}}{\rgtmk}
word

\def\lftmk{(}
\def\rgtmk{)}

word
\scaleleftright[2ex]{\lftmk}{\parbox{4cm}{\mytext\mytext}}{\rgtmk}
\scaleleftright[2ex]{\lftmk}{\parbox{4cm}{\mytext}}{\rgtmk}
word

\end{document}

在此处输入图片描述

使用 scalerel，甚至不可调节的符号也可以用作分隔符，例如<和>等。该scalerel包将对它们进行缩放。

答案2

下面是我为解决我的问题而编写的一段代码：一种解决方法，使用两个命令包装在一个 mbox 中以使其适合一行：尽情享受吧！

命令：

%Savebox:
\newsavebox{\leftbox} \newsavebox{\rightbox}
% Dual Convo Command:
 % Dual Left Command:
 \NewDocumentCommand{\ldboxbrace}{s O{\{} O{\}} O{0.04\linewidth} m O{0.38\linewidth} m}{% \lrboxbrace[<lbrace>][<rbrace>][<lwidth>]{<ltext>}[<rwidth>]{<rtext>}
 \begin{lrbox}{\leftbox}% Left box
 \IfBooleanTF{#1}% starred/unstarred
 {\begin{varwidth}{#4}#5\end{varwidth}}
 {\begin{minipage}{#4}#5\end{minipage}}
 \end{lrbox}
 \begin{lrbox}{\rightbox}% Right box
 \IfBooleanTF{#1}% starred/unstarred
 {\begin{varwidth}{#6}#7\end{varwidth}}
 {\begin{minipage}{#6}#7\end{minipage}}
 \end{lrbox}
 \ensuremath{\usebox\leftbox\left#2\,\usebox\rightbox\,\right#3}
 }
 % Dual Right Command:
 \NewDocumentCommand{\rdboxbrace}{s O{\{} O{\}} O{0.38\linewidth} m O{0.04\linewidth} m}{% \lrboxbrace[<lbrace>][<rbrace>][<lwidth>]{<ltext>}[<rwidth>]{<rtext>}

 \begin{lrbox}{\leftbox}% Left box
 \IfBooleanTF{#1}% starred/unstarred
 {\begin{varwidth}{#4}#5\end{varwidth}}
 {\begin{minipage}{#4}#5\end{minipage}}
 \end{lrbox}
 \begin{lrbox}{\rightbox}% Right box
 \IfBooleanTF{#1}% starred/unstarred
 {\begin{varwidth}{#6}#7\end{varwidth}}
 {\begin{minipage}{#6}#7\end{minipage}}
 \end{lrbox}
 \ensuremath{\left#2\usebox\leftbox\right#3\usebox\rightbox}
 }

例子：

\begin{center}
\mbox{
\ldboxbrace {abc} % The left bracket
    {Loren ipsum dolor sit amet, consectetur adipiscing elit. Sed
  eleifend tincidunt enim, eu tincidunt felis auctor quis. Aenean eget
  enim urna.  Pellentesque tincidunt adipiscing velit a
  fermentum. \endgraf Lorem ipsum dolor sit amet, consectetur
  adipiscing elit. Sed eleifend tincidunt enim, eu tincidunt felis
  auctor quis. Aenean eget enim urna.  Pellentesque tincidunt
  adipiscing velit a fermentum.}

\rdboxbrace  {Loren ipsum dolor sit amet, consectetur adipiscing elit. Sed
  eleifend tincidunt enim, eu tincidunt felis auctor quis. Aenean eget
  enim urna.  Pellentesque tincidunt adipiscing velit a
  fermentum. \endgraf Lorem ipsum dolor sit amet, consectetur
  adipiscing elit. Sed eleifend tincidunt enim, eu tincidunt felis
  auctor quis. Aenean eget enim urna.  Pellentesque tincidunt
  adipiscing velit a fermentum.} %The rigth bracket
  {abc}
  }
\end{center}

再次感谢大家。

答案3

\begin{array}{lll}
  (\cos(\theta) + i \sin(\theta))^n = \cos(n\theta)+i \sin(n\theta) \space & 
\mbox{where} &
   \left \{
   \begin{array}{lcr}
     \theta \in \mathbb{R} \\
     n \in \mathbb{Z}: n \geq 1 \\
   \end{array}
   \right \}
\end{array}

举个例子。
