为什么要重新发明轮子?enumitem
通过一套密钥系统,您就拥有了所需的所有工具:
\documentclass{book}
\usepackage{enumitem}
\setlength\parindent{1em}
\begin{document}
\begin{description}[style=nextline, leftmargin=0pt, parsep=0pt, listparindent=1em, itemsep=1ex, font =\sffamily\bfseries]
\item[Test1]
This is test 1.
\item[Test2]

This is test 3.
A second (indented) paragraph in the description of this item.
\end{description}
\end{document}
