정렬된 환경에 수직 공간을 추가하고 두 수집/정렬 환경 사이의 동일하지 않은 공간에 대한 설명

Question

aligned더 나은 출력을 얻기 위해 환경 사이에 공간을 두고 환경의 텍스트 아래에 공간을 두고 싶습니다 . 어떻게 해야 합니까?

또한 gather/align텍스트 사이에 텍스트가 있는 환경에서 왜 중간에는 동일한 간격이 없지만 그 위에 더 많은 공간이 있습니까?

&\oint\vec{H}\cdot\vec{dl}=NI\Rightarrow H_{z}\cdot\hat{z}\cdot l \hat{z}=nlI \Rightarrow \vec{H}=nI\hat{z}\\
&\vec{B}=\mu_{0}nI\hat{z}=\mu_{0}nI_{0}\sin (\omega t) \hat{z}\\
&\oint\vec{E}\cdot\vec{dl}=-\frac{d}{dt}\int\limits_{S}\vec{B}\cdot \vec{dS}

Answer 1

그게 더 나은가요? 나는 명령으로 제목 (Ερώτιμα α, &c.)을 amsmath로 바꾸고 만들었습니다 . 또한 Gather* 환경에 중첩되어 있으므로 로 대체됩니다. 그런데 제가 아는 한 요즘 로딩은 쓸모가 없습니다.mathtools\shortintertext\CustomAlign\CustomAlignedxltxtra
