如何消除公式后的缩进

Question

由于我的 LaTeX 方程式相当大，我决定按以下方式增加其大小：

%     
\begin{small}     
   \begin{eqnarray}     
       bla bla bla bla              
   \end{eqnarray}              
\end{small}             
%          
text text text

这里一切看起来都很好，除了公式后面的文本以缩进开始，尽管我%在公式和文本之间添加了缩进。我该如何消除缩进？

Answer 1

这是缩小等式的错误方法。如果您注意的话，等式上方的线条间距会不规则。您看到的小空格是 之后的行尾\end{small}。

以下是使用您的输入的示例：

等式前的行距不当非常明显，如果\footnotesize使用的话会很糟糕。

另外，eqnarray不建议使用；提供的对齐环境amsmath肯定更好。我也不建议使用\begin{small}和\end{small}。<blank line>{\small ...\par}在需要时使用（如果要排版段落，或者{\small ...}在正常大小的段落内）。

有两种可能性；第一种情况，方程式编号将是正常大小；第二种情况，方程式编号也将减小，但将更容易适应对齐环境。

我以前twocolumn只是为了并排展示这两个例子。
