根据小节、文本后的换行符在 Lyx 中对定理/定义进行编号

tag-icon • tag-icon lyx theorems amsthm lyx-layouts
根据小节、文本后的换行符在 Lyx 中对定理/定义进行编号

我目前正在 Lyx 中使用“文档”>“设置”>“模块”>“定理（按章节内类型编号）”。

然而，我需要根据小节对我的定理/定义进行编号。即

2 简介

2.1 小节...

定义2.1.1

定理 2.1.2

2.2 第 2 节

定理2.2.1

此外，我还希望标签后的文本位于新行中（而不是在粗体文本后继续），即

定义2.2.2

公式的定义是...

我还想说明一下，我对 lyx 还很陌生，所以我不熟悉如何在编辑器中编辑 TeX 代码（如果需要），因此如果能提供详细的步骤我将非常感谢。

谢谢你！

编辑 1：MWE（我删除了大部分与字体相关的代码）

我不知道在 LyX 中是否可以实现这一点，但您必须将以下内容添加到序言中才能获得它：

\newtheoremstyle{break}%
{5pt}{4pt}% spaces added before and after the environment
{\itshape}{}%
{\bfseries}{}% % Note that final punctuation is omitted.
{\newline}{}
\theoremstyle{break}
\newtheorem{theorem}{Theorem}[subsection]

\newtheoremstyle{defbreak}%
{5pt}{4pt}% spaces added before and after the environment
{\upshape}{}%
{\bfseries}{}% % Note that final punctuation is omitted.
{\newline}{}
\theoremstyle{defbreak}
\newtheorem{defn}{Definition}[subsection]

在此处输入图片描述

以下是完整代码（略有修改）：

\documentclass{article}
\usepackage{amsthm}
\usepackage{lipsum}

\newtheoremstyle{break}%
{5pt}{4pt}% spaces added before and after the environment
{\itshape}{}%
{\bfseries}{}% % Note that final punctuation is omitted.
{\newline}{}
\theoremstyle{break}
\newtheorem{thm}{Theorem}[subsection]

\newtheoremstyle{defbreak}%
{5pt}{4pt}% spaces added before and after the environment
{\upshape}{}%
{\bfseries}{}% % Note that final punctuation is omitted.
{\newline}{}
\theoremstyle{defbreak}
\newtheorem{Def}{Definition}[subsection]

\begin{document}

\section{Introduction}
\subsection{A first subsection}
\lipsum[3]

\begin{thm}
  A silly test theorem. A silly test theorem. A silly test theorem. A silly test theorem. A silly test theorem.
\end{thm}

\lipsum[4]
\begin{Def}
 This is a \texttt{defbreak} style example. Some text. Some more text. Some more text. Some more text.
\end{Def}
\lipsum[5]

\end{document}

一个好的解决方案是需要制作你自己的模块，但是穷人的解决方案可能是：

1)不加载任何模块。

2）将其插入Document> Stetings...>LaTeX Preamble

\usepackage{amsthm}
\newtheoremstyle{xxx}{}{}{\itshape}{}{\scshape\bfseries}{:}%
{\newline}{\thmname{#1}\thmnumber{ #2}\thmnote{(#3)}\smallskip}%
\theoremstyle{xxx}
\newtheorem{xxx}{\protect\theoremname}[subsection]
\providecommand{\theoremname}{Smart theorem}

\begin{xxx} ... \end{xxx}3)在 ERT 框 ( Ctrl+ ) 中写上你的定理，或者分别为和L写两个 ERT 框，并将定理文本保留为普通段落。\begin{xxx}\end{xxx}

结果必须与此 LaTeX 源代码等效：

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{amsthm}
\newtheoremstyle{xxx}{}{}{\itshape}{}{\scshape\bfseries}{:}%
{\newline}{\thmname{#1}\thmnumber{ #2}\thmnote{(#3)}\smallskip}
\theoremstyle{xxx}
\newtheorem{xxx}{\protect\theoremname}[subsection]
\providecommand{\theoremname}{Smart theorem}
\begin{document}
\section{xxx}
Bla bla bla ...
\subsection{adasd}
\begin{xxx}
Bla bla bla ...
\end{xxx}
Bla bla bla ...
\end{document}

显然，您可以将样式更改xxx为更有意义的名称，并将的参数更改\newtheoremstyle为更适合您所需的布局。运行texdoc amsmath以获取有关参数的信息。
