# 字体字形

## 引言

默认情况下，LaTeX 会使用 $$\text{Computer Modern}$$ 字体族排版文档，但你可以根据需要或偏好使用 LaTeX 宏包来使用不同的字体。

## 更改默认文档字体

例如，通过添加 `\usepackage{tgbonum}` 到文档导言区，LaTeX 将使用 TEX Gyre Bonum 字体族来排版你的文档：

```latex
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tgbonum}

\begin{document}
此文档是用于测试字体
族和字体字形的示例文档。

本文本使用了不同的字体字形
\end{document}
```

[在 Overleaf 中打开此示例](https://www.overleaf.com/docs?engine=pdflatex\&snip_name=Change+LaTeX+fonts\&snip=%5Cdocumentclass%7Barticle%7D%0A%5Cusepackage%5BT1%5D%7Bfontenc%7D%0A%5Cusepackage%7Btgbonum%7D%0A%0A%5Cbegin%7Bdocument%7D%0AThis+document+is+a+sample+document+to+test+font+%0Afamilies+and+font+typefaces.%0A%0AThis+text+uses+a+different+font+typeface%0A%5Cend%7Bdocument%7D)

下图显示了上面示例生成的输出：

## 更改默认字体字形

还可以为文档中的特定元素更改字体。

```latex
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tgbonum}

\begin{document}
此文档是一个用于
测试字体族和字体字形的示例文档。

{\fontfamily{qcr}\selectfont
本文本使用了不同的字体字形
}
\end{document}
```

命令 `\fontfamily{qcr}\selectfont` 将为 *TeX Gyre Cursor* 字体字形，其字体代码为 `qcr`，用于花括号内的文本。还有更多 LaTeX 字体字形可用，参见 [参考指南](#reference-guide).

流行的 LaTeX 字体字形源自四个家族：

* *Computer Modern* （标准 LaTeX 类中的默认字体）：CM Roman、CM Sans Serif、CM Typewriter
* *Latin Modern*：LM Roman、LM Sans Serif、LM Typewriter、LM Dunhill
* *Post Script 字体*：Times、Utopia/Fourier、Palatino、Bookman、Helvetica、Courier
* *TeX Gyre*

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-cn/zi-ti/02-font-typefaces.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
