减少两个或多个积分之间的间距

2024-5-24 • tag-icon

如何使用下面的代码将两个或多个积分之间的空间至少减少到四重积分，以便对它们进行更多的了解？

它可供许多人/用户使用。谢谢大家。

我没有安装mtpro2或classico包，因此无法准确重现您的代码。但是，似乎您可以通过更改定义中的字距来获得所需的输出\upinterkern。

使用你的价值观

\def\upintkern@{\mkern-7mu\mathchoice{\mkern-3.5mu}{}{}{}}

更改-3.5mu为-7mu

\def\upintkern@{\mkern-7mu\mathchoice{\mkern-7mu}{}{}{}}
