我有以下模板：

但是，章节标题和实际页眉之间的间距很大，如下所示：

有人知道如何减少间距吗？作为一个完全的初学者，我希望以以下格式显示章节：编号：标题 1.简介，但我不知道如何做到这一点，任何帮助都将不胜感激。

Answer 1

您可以使用titlesec已加载的包。我修改了代码以使其可编译（例如，代码给出了如下错误：missing \TEST definition或missing custom-acronym style definition），并删除了不需要的包。

我使用减少了上边距和标题之间的空间\vspace{...}；您可以更改此值以获得所需的输出。

需要注意的是：latex 会给出警告，因为该文档oneside但是的设置fancyhdr是针对twoside文档的（因此，一个设置是无用的）。
