對於我的論文，我想將定理放在一個特殊的框框中，為此我創建了一個\specialbox利用 的命令\stackinset，這樣我就可以得到圍繞定理的部分框架。其設計歸功於 Steven B. Segletes，我找到了設計這裡。下面我附上了一張圖片來說明設計和問題（見下文），下面我還包括了 MWE。
問題：對於我已經使用過\stackinset四次的設計。如下圖所示，我們從定理 I 和方程式 (1) 到定理 XVII 和方程式 (17)，即兩者都增加了 16 \stackinset。的情況下\stackinset，計數器增加 2^4 = 16。有人知道解決這個問題的方法嗎？

答案1
在 的定義中，在呼叫 s 之前\specialbox將參數儲存到儲存中，現在應用於儲存（名為）而不是原始參數本身。\parbox\stackinset\parbox\tmpbox
