答案1
我建议你更换
e^{\left(t-\dfrac{t}{RC}\right)}
和
\exp( t-t/RC )
对于内联数学模式和
\exp\Bigl(t-\frac{t}{RC}\Bigr)
用于显示数学模式。对于这两种数学样式,我也会\times
用\cdot
-- 替换,或者干脆\times
完全省略。
请注意以下屏幕截图第一行中两个内联样式分数表达式的使用:
\documentclass{article}
\begin{document}
$v = [Et/RC + 1] \cdot \exp(t-t/RC)$
\bigskip
$\displaystyle v=\Bigl[\frac{Et}{RC}+1\Bigr] \cdot
\exp\Bigl(t-\frac{t}{RC}\Bigr)$
\end{document}

答案2
让我解释一下@david 的评论:
\documentclass{article}
\usepackage{amsmath}
\usepackage{lipsum}
\begin{document}
\lipsum[1][1-2] and more text which contain the following equation
$v = \left[\dfrac{Et}{RC} + 1 \right] \times e^{\left(\textstyle t-\dfrac{t}{RC}\right)}$
and more text \lipsum[1][3-5]
Slightly better result you will get when you not use \verb+\dfrac+ and for exponent use \verb+\exp+:
$v = \left[\frac{Et}{RC} + 1 \right] \times \exp{\left(t-\frac{t}{RC}\right)}$.
\lipsum[66].
However, better is:
\lipsum[1][1-2]
\[
v = \left[\dfrac{Et}{RC} + 1 \right] \times e^{\left(\textstyle t-\dfrac{t}{RC}\right)}
\]
\lipsum[1][3-5] Or better:
\[
v = \left[\frac{Et}{RC} + 1 \right] \times \exp{\left(t-\frac{t}{RC}\right)}
\]
\lipsum[1][6-9]
\end{document}
