你好,我想在乳胶中按原样写下上面的方程式。到目前为止,我有这个:
\begin{multline}\label{EEDIeq}
\frac{\Bigg(\prod_{j=1}^n f_j\Bigg)
\Bigg(\sum_{i=1}^{nME}P_{ME(i)}.C_{FME(i)}.SFC_{ME(i)}\Bigg) +
(P_{AE}.C_{FAE}.SFC_{AE})+ \\
\Bigg(\Bigg(\prod_{j=1}^n f_j.\sum_{i=1}^{nPTI} P_{PTI(i)}-
\sum_{i=1}^{neff}f_{eff(i)}.P_{AEeff(i)}\Bigg) C_{FAE}.SFC_{AE}\Bigg) -\\
\Bigg(\sum_{i=1}^{neff}f_{eff(i)}.P_{eff(i)}.C_{FME}.SFC_{ME}\Bigg)}{f_i.f_c.f_l.Capacity.f_w.V_{ref}}
\end{multline}
但这给出了错误。我该如何修复?

一些不需要的回车符导致了该问题,下面是更新后的代码:
\documentclass{book}
\usepackage{amsmath}
\begin{document}
\begin{multline}\label{EEDIeq}
\frac{\Biggl(\prod_{j=1}^n f_j\Biggr)
\Biggl(\sum_{i=1}^{nME}P_{ME(i)}.C_{FME(i)}.SFC_{ME(i)}\Biggr) +
(P_{AE}.C_{FAE}.SFC_{AE})+
\Biggl(\Biggl(\prod_{j=1}^n f_j.\sum_{i=1}^{nPTI} P_{PTI(i)}-
\sum_{i=1}^{neff}f_{eff(i)}.P_{AEeff(i)}\Biggr)
C_{FAE}.SFC_{AE}\Biggr) -
\Biggl(\sum_{i=1}^{neff}f_{eff(i)}.P_{eff(i)}.C_{FME}.SFC_{ME}\Biggr)}{f_i.f_c.f_l.Capacity.f_w.V_{ref}}
\end{multline}
\end{document}
但请确认您确实希望该等式在同一行吗?
