当我从备份中首次编译代码时，它运行良好。当我将另一个文档中的一段复制到仅包含文本和少量引文的第 2 章时，它会在下一章（第 3 章）的enumerate命令中给出错误，而之前该命令运行良好。错误消息是“定义中的参数编号非法\NewCount。\begin{enumerate}”。然后，如果我撤消所做的更改并尝试编译，它再次给出相同的错误。我不知道如何解决这个问题，我迫切需要快速帮助，因为我必须尽快完成我的报告。
我正在尝试创建最小工作示例。但是，与此同时，我卸载了 MikTex 和 Texstudio，然后重新安装它们。然后尝试编译，它工作正常，除了 biber 不是最新的，并且引用没有显示。因此，我从控制台更新了 MikTex，然后编译并出现旧错误。我认为更新有问题？
这是我创建的 MWE 和相应错误消息的屏幕截图。

答案1
这更像是一个扩展的评论而不是答案：
- 显然，您使用了一个非常古老的“模板”，该模板使用的语法
\it\bf已经过时 20 多年了（但不知何故仍然有效……）。在文本中，正确的语法是\textit{...}或{\itshape ...}，\textbf{...}或{\bfseries ...}，和 在数学环境中\mathbf{...}，或者\bm{...}如果您使用bm粗体数学字母包（变量） - 我怀疑粗体变量表示向量和矩阵，如果是这样，为什么在某些方程式中使用符号
\vec{x}？ - 在编写数学表达式时可以方便地
physics或esdiff打包。它们支持方便的方式来编写导数，以及其他数学运算符，例如梯度等。 - 我提到了我的问题
biblatex：我的biblatex安装有问题（我没有使用它），选项maxcitenames不起作用（但这似乎对你有用） 为了消除您的问题，我建议您测试以下 MWE：

- 下一步是将您的文本添加到我的平均能量损失。在文本中，请首先纠正我在评论中提到的所有内容，并考虑上面的方法平均能量损失书面。
- 如果上述平均能量损失不起作用，那么首先查看编辑器中的设置（如果它使用 Unicode 编码），如果没有任何帮助，请尝试重新安装 LaTeX 发行版或尝试使用 Overleaf 在线服务。
- 如果我的平均能量损失无法与您的 配合使用
\documentclass，那么它可能以某种方式损坏或对itemize环境进行了重新定义。在这种情况下，您需要查看其代码或最好使用其他最新的“模板”。
我希望这个扩展评论能对你有所帮助。平均能量损失以上产生以下结果，没有任何错误，坏框或警告：
