外部链接的引入方法。注意，链接的名字和用一对尖括号包裹起来的链接地址之间必须有一个空格。链接最后的下划线和片段的后续内容之间也需要
有一个空格。</p>

<p>基本的文本样式：这是 <em>斜体</em> ，这是 <strong>加粗</strong> ，接下来的则是行间公式 <code class="docutils literal notranslate"><span class="pre">a0</span></code> 。它们的前后都需要有一个空格隔开其他内容，这个让人挺不爽的…</p>
<p><a class="reference external" href="https://docs.readthedocs.io/en/stable/guides/cross-referencing-with-sphinx.html#the-doc-role">这是</a> 一个全面展示
章节分布的例子，来自于 ReadTheDocs 的官方文档。事实上，现在我们也采用 ReadTheDocs 主题了，它非常美观大方。</p>
