我的第一节标题与页眉冲突，但后续节标题均不冲突。我该如何修复此问题？

Answer 1

MWE 生成以下包警告fancyhdr：

Package Fancyhdr Warning: \headheight is too small (12.0pt):
 Make it at least 34.43335pt.
 We now make it that large for the rest of the document.
 This may cause the page layout to be inconsistent, however.

解决方法是\headheight根据需要增加。这可以通过headheight包选项来完成geometry：

\usepackage[
  a4paper,
  left=25mm,
  right=25mm,
  top=25mm,
  bottom=25mm,
  headheight=34.5pt,
]{geometry}
