在编辑论文某一章的引文时，我遇到了几十个如下的错误，并且无法再将文件编译为 pdf：
*Missing \endcsname inserted.
<to be read again>
\unhbox
l.420 ...dre_left_2007}{nyt/global//global/global}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.*
看来引用或 output.aux 文件有问题。我尝试清除缓存，但没有帮助。
有人知道这是怎么回事吗？我会很感激任何提示！这是我的 .tex 文件：
