乳膠積分標誌很短

我對乳膠有點陌生，我試著用積分寫一個方程式。

如下圖所示，\int \dee x與被積函數相比，由 產生的積分符號看起來非常小。

沒有幫助的解決方案

  • 在閱讀多個類似的問題後，我得到的最接近的是使用\displaystyle.唯一的缺點是使用\displaystyle插入的不需要的行間距。
  • 我嘗試使用該bigints包，但無法編譯乳膠文件。

目標 要產生適當大小的積分符號，而不需要對佈局進行任何其他更改（例如增加行距），這很容易複製和實現（是的，我可以找到一些複雜的方法來更改所有內容並觀察我想要的內容，但必須有一種添加抽象的更好方法。

pdflatex --version這是相關情況下的輸出。

感謝您的回复，據我所知，我的問題不清楚，所以我在這裡詳細說明。

新增顯示樣式後，渲染如下所示： 在此輸入影像描述

正如您所看到的，積分的大小更合適，但線之間有很多不需要的空間。我希望行距與第一個渲染相似，積分符號與第二個渲染相似。

  • 基本上，我（希望）正在尋找的實現類似於\left[\right]它如何調整高度以匹配其內容。

答案1

您顯示的間距不是由於\displaystyle（或至少不是直接）您有平衡的列，因此 tex 拉伸空白以使它們的長度相等。如果您用於multicols*不平衡列，並使用\newcolumnnot \columnbreak，您將獲得
