使用 iosart2x 时如何删除 latex 中的行号

Question 1

对于 (2022/09/12) 的 1.3.50 版本iosart2x，可在https://github.com/vtex-soft/texsupport.iospress-sat/tree/master在撰写本文时（2024 年 3 月），类选项crcready实际上正在运行（类的 1.3.12 版本并非如此）。该类选项会删除行号。此外，它还会删除页面顶部的期刊信息和版权声明，并删除页码。

要仅删除行号并保留其余信息，另一种方法是在序言\numberlinesfalse之后使用\begin{document}，或者等效地\AtBeginDocument{\numberlinesfalse}在序言中使用。

\begin{abstract}
The abstract should be clear, descriptive, self-explanatory and no longer than 200 words. It should also
be suitable for publication in abstracting services. Do not include references or formulae in the abstract.
\end{abstract}

\begin{keyword}
\kwd{Keyword one}
\kwd{keyword two}
\kwd{keyword three}
\kwd{keyword four}
\kwd{keyword five}

\section{Introduction}
The instructions are designed for the preparation of a camera-ready and accepted paper in \LaTeX{} and should be read carefully.
Prepare your paper in the same style as used in this sample pdf file.
These instructions also contain the necessary information for manual editing.

Manuscripts must be written in English. Authors whose native language is not English are recommended to seek the advice of a native English speaker,
if possible, before submitting their manuscripts. In the text no reference should be made
to page numbers; if necessary, one may refer to sections. Try to avoid excessive use of italics and bold face.

\begin{document}
\numberlinesfalse
\begin{frontmatter} % The preamble begins here.
% etc, same as above

对于 1.3.12 版本iosart2x（2019/11/20），解决方案与其他答案。以下代码删除行号（注意添加的代码需要放在后 \begin{document})：

\begin{document}
\makeatletter
\let\put@numberlines@box\relax
\makeatother
\begin{frontmatter} % The preamble begins here.

还要注意，crcready不使用类选项（与类手册中当前提供的说明相反）。

结果：
