我正在用它写论文，pdflatex到目前为止没有遇到任何问题。当我编写论文时，我没有遇到任何错误。但是句子的一部分突然丢失（因此一行的一部分只是空白）。我试图找出原因，似乎如果我删除段落最后一句（或其他地方）中的一个或两个单词，文本看起来就没问题了。有人知道为什么会这样吗？昨天所有参考资料都很好，一切都编译得很好。今天我添加了教授的一些小更正，突然就发生了这种情况。
如果我单独编译具有相同序言的相同段落，则不会出现此问题。
我附加了两张图片来说明问题：
文档编译中：
单独编译：
如果 MWE 示例有帮助，我可以这样做，但显然一切正常，只是文本随机丢失......
这是一个或多或少最小的工作示例：

The structures of these PN ring systems have been extensively studied in the solid state
\via single crystal X\mbox{-}ray crystallography, where in a predominant number of cases
only the thermodynamically favoured \textit{cis} isomers can be observed.
\pnmr experiments on the other hand suggest that both \textit{cis} and \textit{trans}
species can be encountered in nearly equal amounts in solution.\supercite{Stahl2000}
Although there is a general consensus in the literature that the \textit{cis} isomer is
the more stable product, little is known about the reasons for this trend.
Low\mbox{-}level \textit{ab\mbox{ }initio} and semi\mbox{-}empirical calculations
presented by Haiduc and co-workers in 1994 provide insight into the source of puckering,
but fail to explain observed stabilities.\supercite{Silaghi-Dumitrescu1994}
Another related facet of cyclodiphosphazane chemistry that has received little attention
is the mechanism of ring inversion, where vertex inversion at the phosphorus, edge
inversion at the imino nitrogen and a sequence of cycloreversion and cycloaddition have
been proposed.\supercite{Chen1985,Wirringa1995,Silaghi-Dumitrescu1998,Schranz1999} %,
