Latex如何将题目和作者左对齐

在导言区写：

\makeatletter
\newcommand\sixteen{\@setfontsize\sixteen{17pt}{6}}
\renewcommand{\maketitle}{\bgroup\setlength{\parindent}{0pt}
\begin{flushleft}
\sixteen\bfseries \@title
\medskip
\end{flushleft}
\textit{\@author}
\egroup}
\makeatother

然后设置题目和作者：

\title{This is caption}

\author{
	Author1$^{1}$, Author2*$^{1,2}$ \\ \medskip 
	$^{1}$School in China \\ 
	$^{2}$School in UK
}
