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 ), or topological spaces with calligraphic font (such as (
). 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
），或带有书法字体的拓扑空间（例如 （
).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
\[
\mathcal{B} = \{B_{\alpha} \in \mathcal{T}\, |\, U = \bigcup B_{\alpha} \forall U \in \mathcal{T} \}
\]Open this example in Overleaf
This example produces the following output:
此示例生成以下输出：
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}
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}
In this case, not only letters but all characters change their appearance; for example, italicises the entire expression to produce $\mathit{3x^2} $.
在这种情况下，不仅字母，而且所有字符都会改变它们的外观;例如，将整个表达式斜体化以生成
$\mathit{3x^2}.
