Latex 中对齐编号后添加逗号

Question

我的问题是我想在

align

环境中的方程组中的每个方程/行的末尾添加一个彗差。

这是我的方程组：

\begin{align}
\frac{\partial h}{\partial t}+\frac{\partial(uh)}{\partial x}+\frac{\partial (vh)}{\partial y}&= e_wU -V_s \\
\frac{\partial (uh)}{\partial t} + \frac{\partial (u^2h+\frac{g'}{2}h^2)}{\partial x}+\frac{\partial (uvh)}{\partial y} &= +g'hS_x-\frac{\tau_{b_x}}{\rho_{eau}}+f_{corr}hv \\
\frac{\partial (vh)}{\partial t} + \frac{\partial (v^2h+\frac{g'}{2}h^2)}{\partial y}+\frac{\partial (uvh)}{\partial x} &= +g'hS_y-\frac{\tau_{b_y}}{\rho_{eau}}-f_{corr}hu \\
\frac{\partial (C_ih)}{\partial t} + \frac{\partial (uC_ih)}{\partial x}+\frac{\partial (vC_ih)}{\partial y} &= E_i-D_i\\
(1-\varphi)\frac{\partial \eta}{\partial t} &= D_{tot}-E_{tot}
\end{align}

Answer 1

如果您希望在等式末尾添加逗号（或句号），我认为除了手动执行之外没有其他解决方案，可能会在像

\,

这样的小空格后面：

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{align}
     \frac{\partial h}{\partial t}+\frac{\partial(uh)}{\partial x}+\frac{\partial (vh)}{\partial y}&= e_wU -V_s\,,\\
     \frac{\partial (uh)}{\partial t} + \frac{\partial (u^2h+\frac{g'}{2}h^2)}{\partial x}+\frac{\partial (uvh)}{\partial y} &= +g'hS_x-\frac{\tau_{b_x}}{\rho_{eau}}+f_{corr}hv\,,\\
     \frac{\partial (vh)}{\partial t} + \frac{\partial (v^2h+\frac{g'}{2}h^2)}{\partial y}+\frac{\partial (uvh)}{\partial x} &= +g'hS_y-\frac{\tau_{b_y}}{\rho_{eau}}-f_{corr}hu\,,\\
     \frac{\partial (C_ih)}{\partial t} + \frac{\partial (uC_ih)}{\partial x}+\frac{\partial (vC_ih)}{\partial y} &= E_i-D_i\,,\\
     (1-\varphi)\frac{\partial \eta}{\partial t} &= D_{tot}-E_{tot}\,.
\end{align}

\end{document}

相反，如果您想要在方程式编号之后标点符号，您可以使用命令 \tag*{}

 以及诸如 

(1),

、

(2).

 等参数：

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{align}
     \frac{\partial h}{\partial t}+\frac{\partial(uh)}{\partial x}+\frac{\partial (vh)}{\partial y}&= e_wU -V_s \tag*{(1),}\\
     \frac{\partial (uh)}{\partial t} + \frac{\partial (u^2h+\frac{g'}{2}h^2)}{\partial x}+\frac{\partial (uvh)}{\partial y} &= +g'hS_x-\frac{\tau_{b_x}}{\rho_{eau}}+f_{corr}hv  \tag*{(2),}\\
     \frac{\partial (vh)}{\partial t} + \frac{\partial (v^2h+\frac{g'}{2}h^2)}{\partial y}+\frac{\partial (uvh)}{\partial x} &= +g'hS_y-\frac{\tau_{b_y}}{\rho_{eau}}-f_{corr}hu  \tag*{(3),}\\
     \frac{\partial (C_ih)}{\partial t} + \frac{\partial (uC_ih)}{\partial x}+\frac{\partial (vC_ih)}{\partial y} &= E_i-D_i \tag*{(4),}\\
     (1-\varphi)\frac{\partial \eta}{\partial t} &= D_{tot}-E_{tot} \tag*{(5).}
\end{align}

\end{document}
