我有一份具有奇偶规则（twoside类）的文档，因此奇数页的右侧边距有较宽的空间，偶数页的左侧边距有较宽的空间。我想将章节标题（右对齐）放在偶数页的右侧边距上，如下所示
chapter title*
odd page [left margin][content][wide right margin]
even page [wide left margin][content][right margin]*
而不是将章节标题（右对齐）放在奇数页的右边距
chapter title*
odd page [left margin][content]*[wide right margin]
even page [wide left margin][content][right margin]
其中 * 用于显示章节标题到特定边距的位置。有没有办法使用 来修改章节标题格式titlesec？

您可以\cleardoublepage按照描述重新定义这里：
\makeatletter
\renewcommand*\cleardoublepage{\clearpage\if@twoside
\ifodd\c@page \hbox{}\newpage\if@twocolumn\hbox{}%
\newpage\fi\fi\fi}
\makeatother
正如链接中解释的那样，book课程在每章末尾都使用此命令。
