Introduction

Some mathematical elements need to be typeset using fonts containing characters/symbols of a certain style; for example, it is customary to represent real numbers with a blackboard bold font (such as $\mathbb{R}$ ), or topological spaces with calligraphic font (such as ( $\mathcal{T}$ ). This article shows how to use different font styles when typesetting mathematics, starting with the following example:

介绍

一些数学元素需要使用包含某种样式的字符/符号的字体进行排版;例如，习惯上用黑板粗体表示实数（如 $\mathbb{R}$ ），或带有书法字体的拓扑空间（例如（ $\mathcal{T}$ ).本文介绍如何在排版数学时使用不同的字体样式，从以下示例开始：

Let \( \mathcal{T} \) be a topological space, a basis is defined as
\[\mathcal{B} = \{B_{\alpha} \in \mathcal{T}\, |\,  U = \bigcup B_{\alpha} \forall U \in \mathcal{T} \}
\]

This example produces the following output:

Math fonts example

Use of some math font styles requires the line to be added to the document preamble: see the amsfonts package for further information. \usepackage{amssymb}

使用某些数学字体样式需要将该行添加到文档序言中：有关详细信息，请参阅 amsfonts 包。\usepackage{amssymb}

Capital letters-only font typefaces

There are some font typefaces which support only a limited number of characters; these fonts usually denote some special sets. For instance, to display the R in blackboard bold typeface you can use to produce $\mathbb{R}$. The following example shows calligraphic, fraktur and blackboard bold typefaces:

仅大写字母字体

有些字体仅支持有限数量的字符;这些字体通常表示一些特殊的集合。例如，要以黑板粗体字体显示 R，您可以使用它来生成$\mathbb{R}$.以下示例显示了书法、fraktur 和黑板粗体字体：

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\begin{align*}
RQSZ \\
\mathcal{RQSZ} \\
\mathfrak{RQSZ} \\
\mathbb{RQSZ}
\end{align*}
\end{document}

Open this example in Overleaf

This example produces the following output:

RQSZ \\
\mathcal{RQSZ} \\
\mathfrak{RQSZ} \\
\mathbb{RQSZ}

$RQSZ \\ \mathcal{RQSZ} \\ \mathfrak{RQSZ} \\ \mathbb{RQSZ}$

Other mathematical fonts

It is possible to set a different font family for a complete mathematical expression:

其他数学字体

可以为完整的数学表达式设置不同的字体系列：

\begin{align*}
3x^2 \in R \subset Q \\
\mathnormal{3x^2 \in R \subset Q} \\
\mathrm{3x^2 \in R \subset Q} \\
\mathit{3x^2 \in R \subset Q} \\
\mathbf{3x^2 \in R \subset Q} \\
\mathsf{3x^2 \in R \subset Q} \\
\mathtt{3x^2 \in R \subset Q}
\end{align*}

Open this example in Overleaf

This example produces the following output:

3x^2 \in R \subset Q \\
\mathnormal{3x^2 \in R \subset Q} \\
\mathrm{3x^2 \in R \subset Q} \\
\mathit{3x^2 \in R \subset Q} \\
\mathbf{3x^2 \in R \subset Q} \\
\mathsf{3x^2 \in R \subset Q} \\
\mathtt{3x^2 \in R \subset Q}

$3x^2 \in R \subset Q \\ \mathnormal{3x^2 \in R \subset Q} \\ \mathrm{3x^2 \in R \subset Q} \\ \mathit{3x^2 \in R \subset Q} \\ \mathbf{3x^2 \in R \subset Q} \\ \mathsf{3x^2 \in R \subset Q} \\ \mathtt{3x^2 \in R \subset Q}$

Changing fonts for typesetting maths

In this case, not only letters but all characters change their appearance; for example, italicises the entire expression to produce $\mathit{3x^2} $ .
