latex字母字体

一. 花式字体

不同字体宏包下，同一字体的表现不同。一般不用加宏包即可。

黑板粗体字

此字体经常用来表示代表实数、整数、有理数、复数的大写字母。
$\mathbb ABCDEF$：\mathbb {ABCDEF}
$\Bbb ABCDEF$：\Bbb {ABCDEF}

黑体字

$\mathbf ABCDEFGHIJKLMNOPQRSTUVWXYZ$ : \mathbf {ABCDEFGHIJKLMNOPQRSTUVWXYZ}
$\mathbf abcdefghijklmnopqrstuvwxyz$ :\mathbf {abcdefghijklmnopqrstuvwxyz}

打印机字体

$\mathtt ABCDEFGHIJKLMNOPQRSTUVWXYZ$ : \mathtt {ABCDEFGHIJKLMNOPQRSTUVWXYZ}

不添加宏包

  1. \begin{array}{ll|l}
  2.  \texttt{"normal"}      &\texttt{}         & ABCDEFGHIJKLMNOPQRSTUVWXYZ\\
  3.  \texttt{"blackboard"}  &\texttt{\mathbb}  &\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  4.  \texttt{"boldface"}    &\texttt{\mathbf}  &\mathbf{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  5.  \texttt{"typewriter"}  &\texttt{\mathtt}  &\mathtt{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  6.  \texttt{"roman"}       &\texttt{\mathrm}  &\mathrm{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  7.  \texttt{"sans-serif"}  &\texttt{\mathsf}  &\mathsf{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  8.  \texttt{"calligraphic"}&\texttt{\mathcal} &\mathcal{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  9.  \texttt{"script"}      &\texttt{\mathscr} &\mathscr{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  10.  \texttt{"fraktur"}     &\texttt{\mathfrak}&\mathfrak{ABCDEFGHIJKLMNOPQRSTUVWXYZ}\\
  11. \end{array}

实现效果

"normal"ABCDEFGHIJKLMNOPQRSTUVWXYZ"blackboard"\mathbbABCDEFGHIJKLMNOPQRSTUVWXYZ"boldface"\mathbfABCDEFGHIJKLMNOPQRSTUVWXYZ"typewriter"\mathttABCDEFGHIJKLMNOPQRSTUVWXYZ"roman"\mathrmABCDEFGHIJKLMNOPQRSTUVWXYZ"sans-serif"\mathsfABCDEFGHIJKLMNOPQRSTUVWXYZ"calligraphic"\mathcalABCDEFGHIJKLMNOPQRSTUVWXYZ"script"\mathscrABCDEFGHIJKLMNOPQRSTUVWXYZ"fraktur"\mathfrakABCDEFGHIJKLMNOPQRSTUVWXYZ

宏包1：\usepackage[mathscr]{eucal}

  1. \begin{array}{ll}
  2.  \texttt{"normal"}      & ABCDEFGHIJKLMNOPQRSTUVWXYZ\\
  3.  \texttt{"blackboard"}  &$\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  4.  \texttt{"boldface"}    &$\mathbf{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  5.  \texttt{"typewriter"}  &$\mathtt{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  6.  \texttt{"roman"}       &$\mathrm{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  7.  \texttt{"sans-serif"}  &$\mathsf{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  8.  \texttt{"calligraphic"}&$\mathcal{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  9.  \texttt{"script"}      &$\mathscr{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  10.  \texttt{"fraktur"}     &$\mathfrak{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$\\
  11. \end{array}

输出结果

"normal"ABCDEFGHIJKLMNOPQRSTUVWXYZ"blackboard"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"boldface"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"typewriter"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"roman"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"sans-serif"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"calligraphic"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"script"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$"fraktur"$ABCDEFGHIJKLMNOPQRSTUVWXYZ$

宏包2：\usepackage{mathrsfs}

二. 希腊字母

 小写希腊字母

大写希腊字母
