我正在使用 xelatex 撰写论文。我使用 TikZ 包来制作图表。虽然当我检查我的 pdf 时它可以正确地制作图表，但它给出了以下错误
“！缺少 { 插入。”
并且章节标题到处都消失了，尽管小节标题还在显示。为了清晰起见，我添加了论文代码的主文件。如果我删除 tikz 包，那么代码运行正常，只是没有生成图形。问题只出在 tikz 包上，我已经检查了好几次。

答案1
您的问题不是由包引起的，而是由节样式定义中使用的tikz属性引起的。有关详细信息，请参阅scrbook\MakeUppercaseStefan Kottwitz 回答。基于此，看看您对\titleformat{\section}以下内容的定义是否
\titleformat{\section}
{\sffamily\bfseries\fontsize{13}{11}\selectfont\uppercase}% <-- observe difference
{\sffamily\thesection}
{0.2em}
{}
给出了你所期望的：
根据上述定义，我可以无错误地编译您的文档（当然，我在文档中直接写了章节、节和小节标题）。
无关：
我必须承认，我迷失在你的文档中。你真的需要所有这些重新定义吗？顺便说一句，例如，你对字体大小的定义\fontsize{14}{11}是错误的。第一个数字是字体大小，第二个是基线跳跃（必须大于字体大小），也缺失了\selectfont。你为什么不使用更简单的small、或\large、或\Large命令？
