我不知道为什么代码会返回警告错误。我想对齐命名法,但等号没有在同一列下对齐
\begin{equation}\label{key}
\frac{\partial u}{\partial t}=-v\circ \nabla u-u \left(v \left(\mu _a+\mu _s\right)\right)+\int _{4 \pi }\text{v$\mu $}_sp_s \left(\Omega '\rightarrow \Omega \right)u\left(r,\Omega ',t\right)d\Omega '+q(r,\Omega ,t)
\end{equation}
Where,\\
$u(r,\Omega,\textit{E},t)$ &= & angular photon density\\
$t$ & = & time(s)\\
$\mathbit{\Omega}$ &= & direction vector of solid angle in steradian\\
$\mathbit{r}$ &= &position vector\\
$\textbf{v}$ &= & speed vector of photon in the medium\\
$\textit{E}$ &= & Energy of the photon\\
$\mu_a$ &= & absorption coefficients mm^{-1}\\
$\mu_s$ &= & scattering coefficients mm^{-1}\\
$p_s\left(\mathrm{\Omega}^\prime\rightarrow\mathrm{\Omega}\right)$ = is the normalized probability of inscattering events of photons from \mathrm{\Omega}^\prime\ to\ \mathrm{\Omega}\\
$q\left(\mathbit{r},\mathbit{\Omega},t\right)$ &= &photon source term including emission events\\

在这么小的范围内,存在着相当多的差异,包括第一个定义带有 E没有出现在当前等式中。?
我擅自将其重构为对齐环境,我的一些查找和替换快捷方式可能匆忙中被弄脏了。重新查看后,我注意到在第一个 E 之前仍有一个 \textit,不清楚 V 是否需要那个 \textbf
使用 {align} 需要 \usepackage{amsmath},但我可能已将其加载到您的序言中。回顾一下,我还注意到 \text 是 \texttt,如果您希望使用find and replace
ttt,那么最好在添加到您自己的主文件之前在测试副本中执行此操作。
如果您不喜欢,请提出评论,其他更有技能的人可以帮忙。
