我正在写一篇论文，想在章节开始处的 \begin{epigraphs} 环境中的题词之间添加一些垂直间距。
梅威瑟：
\documentclass{report}
\usepackage{setspace}
\usepackage{epigraph}
\setlength{\epigraphrule}{0pt}
\onehalfspacing
\begin{document}
\chapter{Introduction}
\setlength{\epigraphwidth}{.95\textwidth}
\begin{epigraphs}
\qitem{``It's a poor sort of memory that only works backwards.'' \\*%
The White Queen to Alice}%
{--\textsc{Lewis Carroll} $\sim$ Through the Looking Glass}
\qitem{\textbf{Science is}, I believe, \textbf{nothing} but \emph{trained and organised common sense}, differing from the latter only as a veteran may differ from a raw recruit: and its methods differ from those of common sense only so far as the guardsman's cut and thrust differs from the manner in which a savage wields his club.}%
{---\textsc{Aldous Huxley}}
\end{epigraphs}
\end{document}

环境epigraphs是根据 定义的list；所以
\begin{epigraphs}\setlength{\itemsep}{<dimen>}
将会做你所希望的事。
\itemsep要为所有epigraphs环境设置值，请写入
\usepackage{etoolbox}
\patchcmd{\epigraphs}{\qitemlabel}{\qitemlabel\itemsep=<dimen>}{}{}
加载后epigraph（我们在 的定义中的适当位置添加设置\epigraphs，这是 LaTeX 看到 时执行的命令\begin{epigraphs}）。
