以微分方程系统为中心 [英] Centering a system of differential equation

问题描述

我正在尝试编写该系统的微分方程，所有方程都是朝左的方向，但是我想问一下如何将系统在页面中居中。

I am trying write this system of differential equation, all equation it is a left direction, but I would like to ask how to centering the system in the page.

非常感谢

\begin{equation}
\left\{\begin{array}{llll}
\label{eq:siroriginal}
\frac{\mathrm{d} s}{\mathrm{d} t} = \delta -\gamma s-\beta si-sk \\
\frac{\mathrm{d} i}{\mathrm{d} t} = -\gamma i+\beta si-\mu i-ik\\
\frac{\mathrm{d} r}{\mathrm{d} t} = \mu i-rk \\
\end{array}\right.
\end{equation}

推荐答案

您尝试过

\begin{equation}\label{eq:siroriginal}
\left\{\begin{aligned}
\frac{\mathrm{d} s}{\mathrm{d} t} &= \delta -\gamma s-\beta si-sk \\
\frac{\mathrm{d} i}{\mathrm{d} t} &= -\gamma i+\beta si-\mu i-ik\\
\frac{\mathrm{d} r}{\mathrm{d} t} &= \mu i-rk \\
\end{aligned}\right.
\end{equation}

使用合适的amsamth环境并设置制表标记吗？

using an appropriate amsmath environment and setting the tabulation markers?

如果问题仍然存在，请尝试在tex.SE中使用完整的最小可编译文档提出问题。

If the problem still persists, try posing the question with a full minimal compilable document in tex.SE
