我对 '_' 字符有些困惑。每次我运行我的 latex 文档时，它都会给出无用的错误：“！缺少 $ 插入。”。经过一番折腾，我发现是这个引用导致了这个问题：

abstract = {A central problem in cranio-maxillofacial (CMF) surgery is to restore the normal anatomy of the skeleton after defects, e.g., trauma to the face. With careful pre-operative planning, the precision and predictability of the craniofacial reconstruction can be significantly improved. In addition, morbidity can be reduced thanks to shorter operation time. An important component in surgery planning is to be able to accurately measure the extent of anatomical structures. Of particular interest are the shape and volume of the orbits (eye sockets). These properties can be measured in 3D CT images of the skull, provided that an accurate segmentation of the orbits is available. Here, we present a system for interactive segmentation of the orbit in CT images. The system utilizes 3D visualization and haptic feedback to facilitate efficient exploration and manipulation of 3D data. {\textcopyright} 2011 Springer-Verlag.},

我做错了什么？我应该加载额外的包还是其他什么？
编辑：问题已编辑，因为我问错了问题。编辑 2：将标签从 biblatex 更改为 bibtex
答案1
例如，使用url包：
\usepackage{url}
然后在 bib 文件中
doi = {\url{10.1007/978-3-642-25191-7_1}},
