乳胶多线方程

问题描述

时有可能得到multline样的行为在一个聚集环境？我有一个聚集的环境一组方程，但其中之一是太长了，我想起来将其分割成两行其中第一线是左对齐，第二行是右对齐（就像multline）。如果存在对齐各行的一个方式在收集或拆分环境（如flushleft或flushright但在在mathmode功能），这将解决这个问题。

Is it possible to get multline like behavior within a gatherenvironment? I have a set of equations in a gather environment, butone of them is too long, and I'd like to split it up onto two lineswhere the first line is left-aligned and the second line is right-aligned(just like multline). If there is a way of aligning individual lineswithin the gather or split environment (like flushleft or flushright butfunctional in mathmode) this would solve the problem.

推荐答案

在 mathtools 包装具有内 multlined 类似于环境聚集和喜欢，但它需要少量的手动调整的：

The mathtools package has an inner multlined environment similar to gathered and the likes, but it required a small amount of manual tweaking:

\documentclass{article}

\usepackage{amsmath}
\usepackage{mathtools}

\begin{document}

% \begin{multline}
%   \framebox[0.65\linewidth]{\strut} \\
%   \framebox[0.6\linewidth]{\strut} \\
%   \framebox[0.65\linewidth]{\strut} \\
%   \framebox[0.6\linewidth]{\strut}
% \end{multline}

\begin{gather}
  \framebox[0.8\linewidth]{\strut} \\
  \begin{multlined}[b][\linewidth-3\multlinegap]
    \framebox[0.65\linewidth]{\strut} \\
    \framebox[0.6\linewidth]{\strut} \\
    \framebox[0.65\linewidth]{\strut} \\
    \framebox[0.6\linewidth]{\strut}
  \end{multlined} \\
  \framebox[0.4\linewidth]{\strut}
\end{gather}

\end{document}
