问希望能显示出subsubsection，并且把\words{...}放入书签显示，与subsubsection同一层次

希望在书签里能显示出subsubsection

默认情况下就能显示出subsubsection...请展示你「不能体现出subsubsection书签」的具体截图。

\documentclass[fontset=fandol]{ctexart}
\usepackage{hyperref}
\begin{document}
\section{单词}
\subsection{词汇}
\subsubsection{二级词汇}
\end{document}

并且把\words{...}中的单词放入书签显示，与subsection或subsubsection同一层次.

我没有这个字体，字体问题显然与是不是在书签显示，是不是同一层次无关。

加上hyperref提供的\pdfbookmark命令即可。其中level的含义是自解释的。

\documentclass[fontset=fandol]{ctexart}
\usepackage{hyperref}
\usepackage{xcolor}
\newcommand{\words}[1]{\pdfbookmark[2]{#1}{word:#1}\noindent{\huge\textbf{\textcolor{red}{#1}}~~}} 
% \newcommand{\words}[1]{\pdfbookmark[2]{#1}{work:#1}\noindent{\huge\textbf{\textcolor{red}{\fontspec{Avenir}#1}}~~}} 
\begin{document}
\section{单词}
\subsection{词汇}
\subsubsection{二级词汇}
\words{chenchen}
\words{辰辰}
\words{你好}
\end{document}

另外，我不觉得单词应该与\subsection或者\subsubsection同level.

问使用algorithmicx宏包实现论文mamba中算法图微调问题

与原文的最大差异是12pt的字体相对于版面太大了，改用默认的10pt并微调\item[]的定义即可：

\algnewcommand\algorithmicinput{\textbf{Input:}}
\algnewcommand\Input[1]{\item[\,\algorithmicinput]\ #1}
\algnewcommand\algorithmicoutput{\noindent\textbf{Output:}}

问使用forest宏包排版树状结构图对于多行文本如何保持节点的对齐？

基于schemata宏包不做任何微调的话：

\begin{document}
\schema
{
    \schemabox{1 一级标题}

    }
    {
        \schema
        {
            \schemabox{1.1.1 三级标题}

        {
            \schemabox{1.1.2.1 四级标题}

Edit微调

修改\Schema[⟨type⟩]{⟨adjust⟩}{⟨size⟩}调整brace的位置：

Missing character: There is no ) ("29) in font nullfont!
Missing character: There is no ) ("29) in font nullfont!

这不是可忽视的警告！

出现问题的语句是要传给overlay unbroken中的\settowidth：

\newcommand{\my@lemma@overlay@unbroken}[2]{
   %%============== First ==============%%
   \def\rad{7pt}%
   \settowidth{\thmtcbtextlen}{\hspace*{10pt}#1.\ \ifdefvoid{\tcbtitletext}{}{(\itshape\tcbtitletext)}} %<-

这个问题的一个等价的MWE如下：

\documentclass{article}
\usepackage[most]{tcolorbox}
\newlength{\mylength}
\newcommand\mycmd[1]{%
    \settowidth{\mylength}{abcdefg}
    \node at (frame.south west) {\the\mylength};
    \draw[ultra thick,magenta] 
        (frame.north west) 
        -- 
        ([xshift=\mylength]frame.north west)
        node[right,font=\ttfamily] {#1:\the\mylength}
    ;
}
\begin{document}
\begin{tcolorbox}[
        title=A Simple Box,enhanced,
        overlay={\mycmd{A Simple Box}}
    ]
    This is a simple tcolorbox.
\end{tcolorbox}

\newlength{\anotherlength}
\settowidth{\anotherlength}{abcdefg}
\texttt{\the\anotherlength}

\end{document}

这个MWE编译会得到如下警告：

Missing character: There is no a in font nullfont!
Missing character: There is no b in font nullfont!
Missing character: There is no c in font nullfont!
Missing character: There is no d in font nullfont!
Missing character: There is no e in font nullfont!
Missing character: There is no f in font nullfont!
Missing character: There is no g in font nullfont!

且对宽度的测量是不准确的。

该问题又可以进一步简化为「在tikz环境内不能直接使用\settowidth」:

\documentclass[tikz,border=5pt]{standalone}
\newlength{\mylength}
\begin{document}
\begin{tikzpicture}
    \settowidth{\mylength}{abcde}
    % \settowidth{\mylength}{\pgfinterruptpicture abcde\endpgfinterruptpicture}
    \draw (0,0) -- (\mylength,0) node[above right] {\the\mylength};
\end{tikzpicture}

\end{document}

会出现警告：

Missing character: There is no a in font nullfont!
Missing character: There is no b in font nullfont!
Missing character: There is no c in font nullfont!
Missing character: There is no d in font nullfont!
Missing character: There is no e in font nullfont!

解决方法和解释在这里。

不知道是不是：

我想要根据标题长度切换不同的装饰样式，目前无论长度如何都没法切换成功

的一个体现。

问 tcolorbox盒子的定制问题

问题要一个一个问，同时尽可能详细描述。 且同时问多个问题会令人难以回答，也会导致问题严重缺少针对性。试想有人需要查询类似问题，看到这个页面十分难以知道解决问题的核心点在哪里，会大大削弱本提问站的意义。

从你上述的描述中：

我想要根据标题长度切换不同的装饰样式，目前无论长度如何都没法切换成功？

不能期望别人很快读完这100多行之后准确get到什么是「目前无论长度如何都没法切换成功」。请详细说明你是具体是用哪些代码，具体是如何切换的，又是如何体现的「不成功」。

我想要底部装饰采用blur shadow而非drop shadow, 目前报错

如果遇到报错，请贴出命令行的报错信息。我将你的代码中的:

drop shadow={opacity=0.3,shadow xshift=.3pt}

替换为你注释掉的

blur shadow={shadow blur steps=10,shadow xshift=-1pt, shadow yshift=-1pt,shadow blur radius=1.5pt,shadow opacity=35} %一旦改成这个就会报错

在tcolorbox-v6.9.0下并没有报错。

我想要使得背景的渐变颜色更加柔和，也就是增加middle部分（猜的，但是应该也只能这样了），目前一旦盒子跨页，就会出现背景中间很白，怪怪的，出现了背景颜色断层，目前的背景颜色逻辑貌似是在盒子跨页后，上下部分各画各的，都把top color和bottom color来上一遍，颜色的过度太生硬了且出现了断层，与shade[top/middle/bottom color] 这种比起来还有点差距，希望能有个更好点的方案

问题描述中出现了"跨页"，以及大量对颜色形态的描述。但你提供的代码中盒子并未跨页，也缺少图示说明背景颜色如何令人不满意。没有人有魔法水晶球知道你想表达什么。请用提供图片和能直接体现这个需求的例子，另开问题询问为佳。

问 `elegantbook`宏包的使用`biblatex`选项backref=true时跳转位置不准确？

问题冲突的根源在于\maketitle内的这一行：

\renewcommand*{\maketitle}{%
\hypersetup{pageanchor=false}
\pagenumbering{Alph}
\begin{titlepage}
...
\end{titlepage}
\restoregeometry
\thispagestyle{empty}}

至于模板设计时为何要在标题去掉pageanchor，有没有其他重要的考量....暂时没什么头绪...

应该可以直接patch掉...

\begin{filecontents*}[overwrite]{refs.bib}

  author       = {Aristotle},
  title        = {De Anima},

\section{Bibliography}

This template uses biblatex to generate the bibliography, the default citestyle and bibliography style are both \lstinline{numeric}. Let's take a glance at the citation effect. ~\cite{anima} use data from a major peer-to-peer lending

In order to get the editors' auto-completion working, you need to add following code in your preamble:

\lipsum

\printbibliography[heading=bibintoc, title=\ebibname]

\end{document}

问为什么目录超过一页就会产生空白页？

甚至不愿意给一个链接来说明是哪个美赛模板...提问要言之有物。

群里已由@u128385 老师解决。

应该在这里补上相关信息...否则这个链接的提问毫无意义...

问如何调整图表标题与正文之间的间距

应该掌握正确的提问姿势，提供最小工作示例。

阅读：https://ask.latexstudio.net/ask/article/644.html

文档具体采用的是哪一种字号(`10pt`?)? 是否调用`caption`宏包? 对间距的行为都有影响，因此MWE总是重要的。

既然已经在本站提过30+个问题，我不认为你不知道应该提供MWE...

问如何输出垂直居中的文本

模仿\raggedbottom、\flushbottom的方案：

\documentclass{article}
\usepackage[
  paperwidth=120mm,
  paperheight=80mm,
  margin=10mm,
  showframe
]{geometry}
\usepackage{lipsum}

\begin{document}

\makeatletter
\def\@texttop{\vskip \z@ \@plus 1fil}
\makeatother

\section{abc}

\lipsum[2-3]

\newpage
\section{def}

\lipsum[2][1-3]

\end{document}

忽然发现我有一点理解错...我以为你需要的是对所有文本没垂直居中的页面都居中... Anyway...

问 circuitikz宏包绘制滑动电阻问题及微调元件位置

本着学习的心态，我咨询了 TSE 上circuitikz的大神 @cis

这里的目标是要实现「单端的」电位器元件Potentiometer，可以只使用其genericpotentiometershape 这一底层的 PGF 节点形状：

其他内容手动使用tikz的路径实现即可：

    % circuitikz/resistors/width=0.7,% default 0.8 ---> R and pR
