问 texstudio如何编译biblatex+biber？

问公式和参考文献引用。

还是下午的问题。你核心的地方是 \maketitle 出错而导致编译无法通过。你拿到这个模板之后，用一些有意义的单词来取代它模板原本的东西都好过直接用 * 来替换。
我现在把我改过的文本贴在这里。

We introduce the problem's setting in Section~\ref{formulation}. 

\section{Mathematical Formulation}\label{formulation}
We consider 

\begin{equation}\label{balance}
\sum_{i\in\overline S}x^0_i-\sum_{i\in \overline S}a_i=\sum_{i\in\overline S}(x^0_i-a_i)^+-\sum_{i\in\overline S}(a_i-x^0_i)^+=0.
\end{equation}

 We denote $\tilde X^0(p)$ as the set of $x^0$  that satisfies Eq. (\ref{balance})

问如何在中文文本下加彩色下划线，并随着中文换行下划线也换行

\documentclass{ctexart}
\usepackage{xeCJKfntef}
\usepackage{xcolor}

\begin{document}
\CJKunderline[format=\color{red}]{这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本这是一段长文本}

问在ctexbook使用目录、chapter 时，目录和正文的起始处，没有在第一行出现，一般第十行左右，且这个起始页没有页眉，请问如何解决？

在章的首页不出现页眉、页脚是通例了，没什么好大惊小怪的。
至于你说的第一个问题，或许是因为章标题的设置造成的？这个以往没有怎么追究过。
你的代码……嗯……一言难尽……推荐多写些基础的东西，好好练练。

问角的° ，在很多数学书中都是和数字是有一定间距的，且高度一般比较高，但LaTeX的基本 °却很近，很低。请问如何解决的

没考虑过这个问题。一般我用 siunitx 包提供的 \ang 命令。

问关于MDPI期刊模板的两个问题！

mdpi.cls 第941行规定 \AfterEndPreamble 然后就有了 \begin{paracol}{2}。除了这一处，在 mdpi.cls 中还有其他2处用了 \begin{paracol}，自己找找。
读一下 template.tex 第363-367行，你会找到你的答案。

问改变字体族和字体形状的命令与前后文之间需要插入空格吗？

其实我习惯于在所有的汉字、英文之间加上空格，不过这只是一种习惯，不知道现在 xeCJK 到底怎么规定的汉字、英文之间的间隙

问 LaTeX在VS code里面怎么用bib文件编译参考文献

同上，常规的时候我用 latexmk 完成，只不过我设计了两个，即 latexmk-pdf 和 latexmk-xe，它们的配置，我写在 install-latex-guide-zh-cn 附录里面了。

问同名参考文献同时引用

先给个最小工作示例

\documentclass{article}
\usepackage[round]{natbib}
\bibliographystyle{abbrvnat}
\begin{document}
\citep{adams2003sobolevone,adams2003sobolevtwo}
\bibliography{ref}
\end{document}

bib 文件是

% Encoding: UTF-8

@Book{adams2003sobolevtwo,
  author    = {Adams, R. A. and Fournier, J. J. F. and Somebody},
  publisher = {Academic Press},
  title     = {Sobolev Spaces Two},
  year      = {2003},
  address   = {New York},
  isbn      = {9780080541297},
  series    = {Pure and Applied Mathematics},
}

@Book{adams2003sobolevone,
  author    = {Adams, R. A. and Fournier, J. J. F. and Somebody},
  publisher = {Academic Press},
  title     = {Sobolev Spaces One},
