我无论如何都无法让我的章节标题正确居中。我希望文档的总体布局有一个相当大的左边距（3.0 英寸）。当我想将某个东西（比如图片）移到该边距中时，我会使用调整宽度。这对于图形等东西很有效。我试图对章节标题采取类似的方法，但不起作用。它一直将其置于边距为 3.0 英寸的文本上方，而不是像我希望的那样将其置于页面中央。或者它会将其放置在页面的 1/3 左右。我做错了什么？

您实际上不必使用adjustwidth:titlesec有工具来实现这一点：\titlespacing它接受 3 个参数，第一个参数用于更改标题的左边距。操作如下：
\documentclass{article}
\usepackage[left=3.0in, right=1.0in, top=1.0in, bottom=1.0in, marginparwidth=2.0in, showframe]{geometry}
\usepackage[export]{adjustbox}
\usepackage{marginnote}
\usepackage{titlesec}
%\titleformat{command}[shape]{format}{label}{sep}{before code}[after code]
\titleformat{\section}[display]{\bfseries\Large\filcenter}{Section \thesection}{0ex}{}[]
\titlespacing*{\section}{-2in}{4.5ex}{2.5ex}
