为了准备与 ACS 期刊进行交流，我使用了 achemso 包和以下标题
\documentclass[journal=jacsat,manuscript=communication]{achemso}
然后，在定义作者之后，我以以下内容开始撰写文档
\begin{document}
\begin{abstract}
Here goes my abstract...
\end{abstract}
令人惊讶的是，当我在不同的机器上使用 pdflatex 编译此文档时，我得到了不同的结果。使用 MacTex 编译时，我发现摘要的格式正确，使用了 ACS 所需的无衬线字体。当我使用 texlive 编译时，摘要在文档的最后一页显示为单列，位于正文、致谢和参考文献之后。
如果我在输入中包含 \listfiles 命令，我会得到两个分布的不同结果。这是执行“diff right.tex error.tex”后两者输出之间的差异
