这是正常的，因为有些字段缺省，下面是引用会议和专著的例子：

• 会议需要注意是否有address和publisher字段。

  @inproceedings{foerster2018counterfactual,
  address = {New Orleans, Louisiana},
  author = {Foerster, Jakob N. and Farquhar, Gregory and Afouras, Triantafyllos and others},
  booktitle = {Proceedings of AAAI Conference on Artificial Intelligence (AAAI)},
  pages = {2974--2982},
  publisher = {AAAI},
  title = {{Counterfactual multi-agent policy gradients}},
  year = {2018}
  }

• 专著类似，需要注意是否有address和publisher字段。

  @book{chen2023cellular,
  title={{Cellular vehicle-to-everything (C-V2X)}},
  address = {London},
  author={Chen, Shanzhi and Hu, Jinling and Zhao, Li and others},
  year={2023},
  publisher={Springer Nature}
  }
