使用 a0poster (\include Vs. \input) 的未定义引用

Question

我有一份a0poster文档（见下面的示例），它没有加载交叉引用，尽管bibtex它运行正常并编译了引用。

我将正文写入不同的tex文件并将其包含到主 tex 文件中（两者都可以在下面找到）。

如果文件text.tex使用 包含\include，则交叉引用会失败。如果使用 包含\input，则一切正常。为什么？

PS：下面的文件main.tex有很多\usepackages以及一些类所需的定义a0poster。

您不能使用\include此类；该\include机制需要分页符，无法在海报中执行。实际上a0poster（或由其输入的包）重新定义\clearpage为不真正发出分页符。

由于\include没有看到必要的分页符，标签无法正确写入辅助.aux文件中，因此导致标签丢失。事实上，代码

\newlabel{eq:myEqn1}{{1}{1}{}{equation.0.1}{}}

出现在.log文件中，这意味着执行.aux时该文件未正确打开。\label

看何时应使用 \input 和 \include？尤其是重新定义 \include以供参考。
