对齐环境中的文本

Question

有没有办法协调这里的空间？

\documentclass[a4paper, 12pt, oneside, titlepage]{scrbook}

\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{colortbl}

\begin{document}

\begin{align*}
P\textcolor{red}{_n} &= 1000 - {q_S} - q_{M\textcolor{red}{_n}} \\
\intertext{\center{bzw.}} \
P\textcolor{blue}{_h} &= 1000 - {q_S} - q_{M\textcolor{blue}{_h}}
\end{align*}

\end{document}

Answer 1

您发现这\center是一个非常危险的命令，它只能在其他环境的定义中使用。

您需要的是\centering（或完全不同的方法）。使用\shortintertext（需要mathtools）您会得到更少的空间。

\documentclass[a4paper, 12pt, oneside, titlepage]{scrbook}

\usepackage{amsmath,mathtools}
\usepackage{xcolor}

\begin{document}

\begin{align*}
P_{\textcolor{red}{n}} &= 1000 - {q_S} - q_{M_{\textcolor{red}{n}}} \\
\intertext{bzw.}
P_{\textcolor{blue}{h}} &= 1000 - {q_S} - q_{M_{\textcolor{blue}{h}}}
\end{align*}

\begin{align*}
P_{\textcolor{red}{n}} &= 1000 - {q_S} - q_{M_{\textcolor{red}{n}}} \\
\intertext{\centering bzw.}
P_{\textcolor{blue}{h}} &= 1000 - {q_S} - q_{M_{\textcolor{blue}{h}}}
\end{align*}

\begin{align*}
P_{\textcolor{red}{n}} &= 1000 - {q_S} - q_{M_{\textcolor{red}{n}}} \\
\shortintertext{\centering bzw.}
P_{\textcolor{blue}{h}} &= 1000 - {q_S} - q_{M_{\textcolor{blue}{h}}}
\end{align*}

\end{document}

请注意，用_{\textcolor{red}{n}}代替的下\textcolor{red}{_n}标已正确调整字距。

不同方法共用array：

\documentclass[a4paper, 12pt, oneside, titlepage]{scrbook}

\usepackage{amsmath,array}
\usepackage{xcolor}

\begin{document}

\begin{equation*}
\renewcommand{\arraystretch}{1.2}
\begin{array}{r@{}>{{}}l}
P_{\textcolor{red}{n}} &= 1000 - {q_S} - q_{M_{\textcolor{red}{n}}} \\
\multicolumn{2}{c}{\text{bzw.}}\\
P_{\textcolor{blue}{h}} &= 1000 - {q_S} - q_{M_{\textcolor{blue}{h}}}
\end{array}
\end{equation*}

\end{document}

Answer 2

给你：

\documentclass[a4paper, 12pt, oneside, titlepage]{scrbook}

\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{colortbl}

\begin{document}

\begin{align*}
\P\textcolor{red}{_n} &= 1000 - {q_S} - q_{M\textcolor{red}{_n}} \\
\intertext{\hfill{bzw.}\hfill\mbox{}}
P\textcolor{blue}{_h} &= 1000 - {q_S} - q_{M\textcolor{blue}{_h}}
\end{align*}

\end{document}
