如何僅在出版物中增加標題行之間的行高

Question

我有以下簡單的程式碼：

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[left=1in, right=1in, top=1.3in, bottom=0.85in]{geometry}
\usepackage{amsfonts, amssymb, amsthm}
\usepackage{hyperref}
\begin{document}

 \title{
 \textbf{This is the title of the paper that I will publish soon to get my degree in 
 mathematics}
 }
\date{}
\maketitle
\end{document}

我只需要增加標題行之間的行高（行距）。我怎樣才能做到這一點？

提前致謝。我真的很感謝任何幫助。

Answer 1

\setstretch包裝中的setspace可能會有所幫助。

\documentclass{article}
\usepackage{setspace,lipsum}
\begin{document}

 \title{\setstretch{2}
 \textbf{This is the title of the paper that I will publish soon to get my degree in 
 mathematics}
 }
\maketitle
Just to show that normal text is not affected:
\lipsum[1]
\end{document}
