拆分带有大量括号的长等式——无法消除错误

拆分带有大量括号的长等式——无法消除错误

我已阅读所有使用alignmultline等的答案multlined,但在我的案例中我无法消除错误。此外,使用\left.\right.并不能消除错误。任何帮助表示感谢。使用自动\left\right会产生可怕的高左括号和贫血的右括号,因此所有视觉配对都付诸东流,所以我发布了第二个使用\Biggl和 的等式\Biggr,在我看来看起来好多了。但将线分成两段的错误仍然存​​在。

主要错误在于使用

\int\displaylimits_{<subscript>}{<integrand>}

被积函数周围的括号是无用的(并且是造成您麻烦的原因。

\limits足够了,当然,所有手动调整大小和间距都会产生糟糕的结果。

为了有开口,您必须使用\bigl和关闭\bigr(带有明显的变体)。此外,您选择的尺寸太大了。
