我正在使用我所在大学提供的自定义文件（实际文件名不同）撰写研究提案thesis.sty。使用此样式文件生成的节标题在页面末尾中断。因此，页面末尾有孤立的节标题。在一个实例中，节标题本身内有一个分页符，在这种情况下，节标题的长度超过一行。以下是thesis.sty定义自定义节和子节的文件的片段：

使用我必须使用的 thesis.sty 格式时，章节标题应如下所示：
我还提供了一些额外的细节，以防万一它能提供任何解决这个问题的线索。非常奇怪的是，这个 thesis.sty 的设计方式是，我们应该在节标签后添加一个空白行，否则会导致标题和下一段之间的间距出现问题。
\section{section header}
<leave a blank line>
Start Paragraph from here.
但是，我并不介意在节标签后添加一个空行。这只是一个小麻烦，我稍后会研究。现在我真的不知道如何修复这些孤立的节标题。我查看了这里很多关于同一问题的帖子，但这些解决方案对我都不起作用。如果我需要提供任何其他信息来帮助解决这个问题，请告诉我。非常感谢！
