在下面的乳胶模板中，我需要减少左右边距仅有的在扉页上：
Latex模板： 牛津大学数学研究所博士论文模板
注意：@John Smith 提出的方法也会改变其他页面的边距……
为了澄清问题，请参阅附图：
笔记：我的标题比这个长得多，占据了多行并导致其他信息的空间有限。

答案1
首先在 .cls 文件中添加以下内容：
\RequirePackage{geometry}
然后用以下命令替换\maketitle.cls文件中的命令：
\newgeometry{left=1in, right=1in}将左右边距设置为 1 英寸（您可以更改），然后\restoregeometry恢复为原始布局设置。
\renewcommand{\maketitle}{%
\begin{alwayssingle}
\newgeometry{left=1in, right=1in} % Adjust margins for the title page
\renewcommand{\footnotesize}{\small}
\renewcommand{\footnoterule}{\relax}

我会使用titlepage环境和geometry包命令
\documentclass[12pt]{ociamthesis} % default square logo
%\documentclass[12pt,beltcrest]{ociamthesis} % use old belt crest logo
%\documentclass[12pt,shieldcrest]{ociamthesis} % use older shield crest logo
%load any additional packages
\usepackage{amssymb}
%input macros (i.e. write your own macros file called mymacros.tex
%and uncomment the next line)
%\include{mymacros}
\usepackage[paper=a4paper,top=1in,bottom=1in,right=1.5in,left=1.5in]{geometry}% http://ctan.org/pkg/geometry
%end the preamble and start the document
\begin{document}
\newgeometry{top=1in,bottom=1in,right=2.5in,left=2.5in}
\begin{titlepage}

\author{Keith Gillow} %your name
\college{St Catherine's College} %your college
%\renewcommand{\submittedtext}{change the default text here if needed}
\degree{Doctor of Philosophy} %the degree
\degreedate{Trinity 1998} %the degree date
\maketitle
\end{titlepage}
\restoregeometry
%this baselineskip gives sufficient line spacing for an examiner to easily
%markup the thesis with comments
\baselineskip=18pt plus1pt
%set the number of sectioning levels that get number and appear in the contents
\setcounter{secnumdepth}{3}

% create a title page from the preamble info
\include{dedication} % include a dedication.tex file
