该类jura基于 KOMA 脚本，因此我认为该\lowertitleback命令可能有效，但不幸的是它无法识别（未定义的控制序列）。我正在排版一份法律文件，jura 默认设置解决了我很多问题。不幸的是，文档只有德语版本。
编辑：该\lowertitleback命令需要在之前\maketitle。
梅威瑟：
\documentclass{jura}
\title{big book}
\author{}
\date{}
\begin{document}
\lowertitleback{
here is some text}
\maketitle
\tableofcontents
here is more text
\end{document}

类jura有点过时了。最好使用带有类scrbook和调用包的KOMA-Script scrjura。
可以使用using scrbook（或scrreprt带有选项的类twoside）命令。\lowertitleback
因此，使用以下代码即可获得完整的scrjura文档
\documentclass[%
