我使用多行拆分方程,但在第二行它转到末尾。我们不能将第二行移得更靠前吗?

答案1
multline
如果您不希望最后一行与右侧齐平,则我不会使用它。请改用equation
+ split
。
添加\raisetag{\normalbaselineskip}
后\end{split}
得到与最后一项在同一行的方程式编号。

\newcommand*{\hpheq}{\hphantom{{}={}}}
\begin{document}
\begin{equation}
\begin{split}
\mathcal{A}(\phi + h) - \mathcal{A}(\phi) &
= c_d \int_0^T
\left\{ \int_0^\infty
\left(-\ddot{\phi} + \frac{1}{r^{d-1}}\frac{\partial}{\partial r}
\left(r^{d-1} \frac{\partial \phi}{\partial r}\right)
- 2m^2\phi\right)

答案2
你的等式的主线超出了右边距,所以我把它分成了三行。也许这更接近你想要的。
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{multline}
\mathcal{A}(\phi + h) - \mathcal{A}(\phi)\\
= c_d \int_0^T
\left\{\int_0^\infty \left(-\ddot{\phi} +
\frac{1}{r^{d-1}}\frac{\partial}{\partial r}\left(r^{d-1}
\frac{\partial \phi}{\partial r}\right) -
2m^2\phi\right)hr^{d-1}dr\right\}dt \\
\hfil+ \mbox{ Boundary Terms } + O\left(\|h^2\|\right)~~,\hfil\hfil\hfil
\end{multline}
\end{document}
