编辑2：我确实有这些代码，但仍然收到错误。
最后更新：
我在文档中找到了问号的原因。在 LaTeX 编码中，我没有包含“\usepackage{url}”。我不知道 url 引用需要该代码（在原始文件中，我有很多这样的代码）。一旦我将其包含进去，一切都正常了。
答案1
这个答案解决了问题的原始版本，并反映了发布的代码和参考书目条目的问题。
在文件中输入作者字段的正确方法.bib是：
Surname1, FirstName and Surname2, FirstName2 and Surname3, FirstName3
您需要用逗号分隔每个名字，并用逗号分隔姓氏和名字（或首字母）。所有名字的and顺序必须始终一致。Surname, FirstName
尽管其他一些格式也能起作用（例如，FirstName LastName能被正确处理但处理两个名字的姓氏时会失败），但使用的方法Surname, FirstName 是养成习惯的最佳实践。
.bib您发布的特定条目还存在其他问题：
- 某些字段中的逗号，例如期刊名称后的逗号
- 编辑器字段中的格式；此字段应仅包含姓名，以与常规作者姓名相同的方式输入
- 页码用连字符 (
-) 代替短划线 (--)；这并不总是必要的，但也是一个很好的习惯
但是这些问题都不会导致您在编辑的问题中描述的问题，因为您发布的是来自不同文档的错误。您发布的文档加上.bib您发布的确切条目将生成可编译的文档。虽然参考书目的格式不正确，但文档不会产生任何错误。
