我有一份报告的文档样式，需要将其复制到 LaTeX 格式。我使用的是 pdfLaTeX，仅供参考。本质上，该系统是段落与小节处于同一级别，直到一个部分的第一个小节，之后段落处于小节以下的级别。
它看起来应该是这样的：
1.00 第一部分
1.01 这是第一节中小节级别的段落。
1.02 这也是第一节中小节级别的段落。
1.03 第一小节
1.03.1 这是第一节第一小节的段落级别的段落。
1.03.2 这是第一节第一小节的段落级别的段落。
1.04 第二小节
1.04.1 这是第一节第二小节的段落级别的段落。
尽管我已经使用 LaTeX 很长时间了，但我还是无法掌握这种风格。我得到的是以下 MWE：
\documentclass{article}
%%% TITLE DEFINITIONS %%%
\usepackage{chngcntr} % change the display of counters
\counterwithin{table}{section}
\counterwithin{paragraph}{subsection} % paragraphs counted within subsections
\usepackage[tiny,raggedright,uppercase,noindentafter,toctitles,explicit]%
{titlesec}
\newcommand*{\newpar}{\paragraph{}}
\newcounter{paraintro}[section]
\setcounter{paraintro}{0}
\makeatletter
\@addtoreset{paragraph}{section}
\@addtoreset{subsection}{section}
\renewcommand\thesection{\arabic{section}.\two@digits{\arabic{subsection}}}
\renewcommand\thesubsection{%

\addtocounter{subsection}{\arabic{paraintro}}%
\fi%
\arabic{section}.\two@digits{\arabic{subsection}}%
\addtocounter{paraintro}{-\arabic{paraintro}}%
}
\renewcommand\theparagraph{%

\addtocounter{paraintro}{1}%
\arabic{section}.\two@digits{\arabic{paraintro}}%
\else
\arabic{section}.\two@digits{\arabic{subsection}}.\arabic{paragraph}%
\fi
}
\renewcommand{\thetable}{%
\arabic{section}.\two@digits{\arabic{subsection}} (\alph{table})%
}
\let\oldsection\section
\newcommand{\mysection}[1]{\oldsection{\uppercase{#1}}}
\def\section{\@ifstar{\oldsection}{\mysection}}
\makeatother
\setcounter{secnumdepth}{5}
\begin{document}
\section{First Section}\label{sec:first}
\newpar This is a paragraph at subsection level in the first section.\label{intropar:first}
\newpar This is also a paragraph at subsection level in the first section.It comes after intropar \ref{intropar:first}. \label{intropar:second}
\subsection{First Subsection}\label{ssec:first}
\newpar This is a paragraph at paragraph level in subsection \ref{ssec:first} in section \ref{sec:first}.\label{par:first}
\newpar This is a paragraph at paragraph level in subsection \ref{ssec:first} in section \ref{sec:first}. It comes after paragraph \ref{par:first}.\label{par:second}.
\subsection{Second Subsection}\label{ssec:second}
\newpar This is a paragraph at paragraph level in subsection \ref{ssec:second} in section \ref{sec:first}. It comes after paragraphs \ref{par:first} and \ref{par:second}.\label{par:third}
\end{document}
这并没有给我想要的结果；数字乱七八糟。似乎引用把事情搞砸了。我怀疑这与调用\theparagraph及其同类\ref有关，但我已经搞砸了很长时间，不知道如何解决这个问题。
有人能帮忙吗？
