在如何保持相同的数字重述定理？，Thomas F. Sturm给出了完美的答案，但现在我发现我希望它是“过去完成时”，因为我还希望能够而refer to the restated theorem不仅仅是原始陈述。
但是当我插入时，[label={thm:1-1a}]它\begin{duplicate}{thm:1-1}{~}会编译为重述定理所在的小节的引用或??，具体取决于我插入的位置。当然，这意味着我应该修改的定义，\newtcolorbox{duplicate}但我不知道该怎么做。
答案1
最简单的方法似乎是
\newtcolorbox[auto counter,number within=chapter]%
{duplicate}%
[3][]%
{% Rest of options
}
其中duplicate是单独计算的定理。这将使用\refstepcounter宏，否则将获取在组外定义的label=最后一个内容，在本例中来自。\@currentlabel\subsection

按照我在此处的回答进行更正：如何仅显示对 tcolorbox 的 cleveref 引用的标题？
