背景
我最近将我正在撰写的出版物从elsarticle课堂转到了cas-dc符合期刊出版建议的期刊。
elsarticle
在elsarticle可能会使用类似下面的内容（从这里）让注释出现在标题上：
\title{This is a specimen title\tnoteref{t1,t2}}
\tnotetext[t1]{This document is the results of the research project funded by the National Science Foundation.}
\tnotetext[t2]{The second title footnote which is a longer text matter to fill through the whole text width and over flow into another line in the footnotes area of the first page.}
cas-dc
然而根据文档现在已变成如下形式：
\title [mode = title]{This is a specimen $a_b$ title}
\tnotemark[1,2]
\tnotetext[1]{This document is the results of the research project funded by the National Science Foundation.}
\tnotetext[2]{The second title footnote which is a longer text matter to fill through the whole text width and overflow in to another line in the footnotes area of the first page.}
我已经玩了后者一段时间，但无济于事……文档编译/排版，我看到了作者和标题，我甚至请参阅标题和作者的注释。然而，我不要请参见作者/标题旁边的星号或星号，以表明该注释属于谁。
来自文档的 MWE cas-dc：

此问题是由于一系列不幸的事故造成的：
该
\tnotemark命令将信息保存到.aux文件中，以便在下次运行时生效，但它确实不是（它可能应该）定义该信息在当前运行中生效。els-cas需要一些缩略图，但没有将它们安装在 TeX 可以看到的地方，因此文档类几乎默认会引发错误（修复此问题应该可以解决整个问题：参见https://tex.stackexchange.com/a/514678/134574）。缩略图引发的错误导致您的文档无法成功构建，显然您的 LaTeX IDE/编辑器发现 LaTeX 运行失败并删除了该文件，因此由于缩略图问题，
