命令的问题：titleformat 很重要

Question

这是我在此的头一篇博文。

我正在使用一些命令和包来使标题按照我的论文规范运行，但是当我使用时\titleformat 出现错误：

! Package titlesec Error: Entered in horizontal mode.

See the titlesec package documentation for explanation.
Type  H <return>  for immediate help.
...                                              

l.24 \section{THE ZEROS OF $\zeta(s)$}

我该如何解决这个问题？这是我的代码：

\documentclass[a4paper,12pt]{article}
\usepackage{amssymb,amsmath,amsthm}
\usepackage[cp1250]{inputenc}
\usepackage{indentfirst}
\usepackage{titlesec}
\newtheorem{pro}{Proposition}[section]
\renewcommand{\thesection}{\arabic{section}.}
\titleformat{\section}{\textsc}
\renewcommand{\theequation}{\thesection\arabic{equation}}

\begin{document}
...
\begin{center}
\section{THE ZEROS OF $\zeta(s)$}
\end{center}
\setcounter{equation}{0}
...
\end{document}

Answer 1

\titleformat需要更多参数，你正在使用语法\titleformat*

\documentclass[a4paper,12pt]{article}
\usepackage{amssymb,amsmath,amsthm}
\usepackage[cp1250]{inputenc}
\usepackage{indentfirst}
\usepackage{titlesec}
\newtheorem{pro}{Proposition}[section]
\renewcommand{\thesection}{\arabic{section}.}
\titleformat*{\section}{\scshape\centering}
\renewcommand{\theequation}{\thesection\arabic{equation}}

\begin{document}
...

\section{THE ZEROS OF $\zeta(s)$}

\setcounter{equation}{0}
...
\end{document}

Answer 2

一个实际工作的示例：

\documentclass[a4paper,12pt]{article}
\usepackage{amssymb,amsmath,amsthm}
\usepackage[cp1250]{inputenc}
\usepackage{indentfirst}
\usepackage{titlesec}
\newtheorem{pro}{Proposition}[section]
\renewcommand{\thesection}{\arabic{section}.}
\titleformat{\section}{}{}{0pt}{\textsc}
\renewcommand{\theequation}{\thesection\arabic{equation}}

\begin{document}


...
%\begin{center}
\section{The zeros $\zeta(s)$}
%\end{center}
\setcounter{equation}{0}
...
\end{document}

第四个参数必须是长度。
