\lfloor 和 \vert 的厚度

tag-icon • tag-icon arrays delimiters vertical
\lfloor 和 \vert 的厚度

出于某种原因，我必须在 latex 文件中同时使用\lfloor和\left\vert 。但随着线条数量的增加，很明显它们的粗细不一样，这对我来说看起来不太好看 :(

这是最小的工作环境以及输出的屏幕截图。

显然\lfloor比 厚\vert。

我的问题：有没有办法为它们设置相同的厚度？

非常感谢您的帮助。 在此处输入图片描述

\documentclass[a4paper,11pt,fleqn]{article}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\begin{equation}
&\begin{array}{l}
\text{for}\;n=0,1,\ldots\\
\left\vert\left\lfloor
\begin{array}{l}
\text{for some reason, I have a mixture of
\texttt{lfloor} and \texttt{vert}}\\
\text{but their thickness are not the same}\\
\text{what are my options?}\\
\text{I would like the same thickness for both of them}
\end{array}
\right.
\end{array}
\end{equation}
\end{document}

mathabx确实有一个\thickvert可扩展的分隔符。你可能不想使用mathabx，因此您需要遵循这些步骤仅加载此符号。然后您可以\thickvert使用

\documentclass[a4paper,11pt,fleqn]{article}
\usepackage{amsmath}
\usepackage{amssymb}
\DeclareFontFamily{U}{mathb}{\hyphenchar\font45}
\DeclareFontShape{U}{mathb}{m}{n}{
      <5> <6> <7> <8> <9> <10> gen * mathb
      <10.95> mathb10 <12> <14.4> <17.28> <20.74> <24.88> mathb12
      }{}
\DeclareSymbolFont{mathb}{U}{mathb}{m}{n}
\DeclareFontSubstitution{U}{mathb}{m}{n}
\DeclareFontFamily{U}{mathx}{\hyphenchar\font45}
\DeclareFontShape{U}{mathx}{m}{n}{
      <5> <6> <7> <8> <9> <10>
      <10.95> <12> <14.4> <17.28> <20.74> <24.88>
      mathx10
      }{}
\DeclareSymbolFont{mathx}{U}{mathx}{m}{n}
\DeclareFontSubstitution{U}{mathx}{m}{n}
\DeclareMathDelimiter{\thickvert}{0}{mathb}{"7E}{mathx}{"1F}
\begin{document}
\begin{equation}
\begin{array}{l}
\text{for}\;n=0,1,\ldots\\
\left\thickvert\left\lfloor
\begin{array}{l}
\text{for some reason, I have a mixture of
\texttt{lfloor} and \texttt{vert}}\\
\text{but their thickness are not the same}\\
\text{what are my options?}\\
\text{I would like the same thickness for both of them}
\end{array}
\right.\right.
\end{array}
\end{equation}
\end{document}

您可以使用 设置垂直线，\vrule并使用 添加一条小水平线\rule。确保将内部tabular与[b]底部对齐。

在此处输入图片描述

\documentclass{article}

\usepackage{amsmath}

\begin{document}

\[
  \begin{array}{ l }
    \text{for } n = 0, 1, \dots \\
    \hspace{.5em}% Space between left margin of tabular cell and first \vrule
    \vrule \hspace{.5em}% Vertical rule + space to next \vrule
    \vrule \rule[-.4em]{.5ex}{.4pt}% Vertical rule with little horizontal line
    \begin{tabular}[b]{ l }
      for some reason, I have a mixture of \texttt{lfloor} and \texttt{vert} \\
      but their thickness are not the same                                   \\
      what are my options?                                                   \\
      I would like the same thickness for both of them
    \end{tabular}
  \end{array}
\]

\end{document}
