如果我尝试这个;
Substituting the expression for \(\Psi\) in to the above and rearranging we derive an expression for the vacuum field \(\Psi'\) as a function of \(\mu \),
\begin{equation}
\Psi' = \frac{\Phi_t}{\mu ab\left[1+ \frac{4}{\pi^2}\sum_{m,n \mbox{ odd }} \frac{\alpha_{mn}}{mn}\right]} \\[1ex]
\end{equation}
with the sum being over odd \(m,n\). The total magnetic flux is defined as just the sum of the flu
那么这很奇怪,因为 {m,n \mbox{ odd }} 被强制放在求和的右侧而不是下方。这是因为它在分母上。我该如何解决这个问题?
答案1
总结建议:(1)使用\displaystyle
通常增加分母中和分数的大小\sum
,以及从下标位置更改为和下的极限。(2)使用包中的\textrm
或而不是。使用周围的文本字体,该字体对于下标或极限来说大小不正确,并且可能是错误的字体。(3)此外,以某种方式控制括号的大小以及和下极限所占用的垂直空间也很有用。这可以通过为括号(和)选择明确的大小命令并在极限上使用来完成。\text

如果只想改变极限的位置,则只需使用 来\sum\limits
代替\sum
(但也替换\mbox
)。
