我在我的论文中使用多字母标识符，为其编写了宏，例如：
\newcommand{\spec}{\mathit{Spec}}
在文本中，我总是将这些标识符称为：
some words $\spec$ even more words
然而，在某些文本中，LaTeX 会改变字母之间的间距：输出如下所示
“有些词 S pec 甚至更多词”
而不是通常的
“一些词语指定甚至更多的词语”。
如何防止 latex 添加空格并始终输出后者？
编辑：这是一个最小示例。第一页的间距很奇怪，第二页的间距是正确的。有什么想法吗？

这似乎是 的一个错误；当使用时，它会在章节标题中classicthesis被触发。\b\mathit
\textit当您使用而不是 时，这种情况似乎不会发生\mathit。

还要注意，b标题中的不是大写的；用于\texorpdfstring避免虚假警告。
请不要使用parskip-。
