在文档的最后，我得到了一个新页面，其中包含：
Temporary page!
LATEX was unable to guess the total number of pages correctly.
As there was some unprocessed data that should have been
added to the final page this extra page has been added to
receive it.
If you rerun the document (without altering it) this surplus
page will go away, because LATEX now knows how many pages
to expect for this document.
我知道只需重新编译文档，就可以消除此错误，但我想知道为什么会发生这种情况以及 LaTeX 无法处理哪些未处理的数据。对于引文、目录、表格和图表参考，LaTeX 需要运行两次，但我以前从未见过这个“临时页面！”页面。
