Question

以下是我想以同样的方式在乳胶中写入的方程式：

Answer 1

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
 a=b
\end{equation}
\begin{equation}
 c=d
\end{equation}
\begin{equation}
a^2+b^2=c^2\quad\text{and}\quad\mathrm{e}^{\mathrm{i}\omega t}
\tag{\stepcounter{equation}\theequation,\stepcounter{equation}\theequation}
\end{equation}
\begin{equation}
 h=k
\end{equation}
\end{document}

Answer 2

\documentclass[preview,margin=5mm]{standalone}
\usepackage{amsmath}
\begin{document}
\begin{equation}
a\times b = c \quad\text{and}\quad a + b = d
\end{equation}
\end{document}

额外服务

如果您需要在不离开显示的方程环境的情况下进行文本间转换，请\intertext按如下方式使用。

\documentclass[preview,margin=5mm]{standalone}
\usepackage{amsmath}
\begin{document}
This is a sentence before my important formulae.
\begin{gather}
a\times b = c \qquad\text{and}\qquad a + b = d\\
\intertext{I can also show another sentence without leaving the gather environment. Is it cool, right?}
E= m c^\text{two}
\end{gather}
A sentence after the gather environment.
\end{document}

笔记

我使用standalone文档类而不是只是article为了使附加的图像更紧凑。将其替换为最适合您的任何文档类。
