如何将我的长方程式放入我的页面中？

Question

我在乳胶中将这个长方程分成几行，但是当我将乳胶放入 PDF 中时，方程式并没有全部显示出来。有什么可以帮帮我的吗？

\begin{equation}\label{eq:20}
\begin{split}
\{T_{1} \in (x_{1},x_{1}+h_{1}],\dots,T_{n} \in (x_{n},x_{n}+h_{n}], N(t)=n\} = \\ 
&\{N(0,x_{1}]=0, N(x_{1},x_{1}+h_{1}] = 1, N(x_{1}+h_{1},x_{2}]=0, \\ 
& N(x_{2}, x_{2}+h_{2}]=1,\dots, N(x_{n-1}+h_{n-1},x_{n}]=0, \\ 
& N(x_{n},x_{n}+h_{n}]=1, N(x_{n}+h_{n},t]=0\}
\end{split}
\end{equation}

Answer 1

您需要在第一行中使用&。相反，我建议基于 from\MoveEqLeft和mathtools环境\fleqnfrom 的以下两种解决方案之一nccmath：

\documentclass{article}
\usepackage{mathtools, nccmath}

\begin{document}

Some text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text. Some more text.

\begin{equation}\label{eq:20}
\begin{split}
 \MoveEqLeft[3] \{T_{1} \in (x_{1},x_{1}+h_{1}],\dots,T_{n} \in (x_{n},x_{n}+h_{n}], N(t)=n\} = \\
&\{N(0,x_{1}]=0, N(x_{1},x_{1}+h_{1}] = 1, N(x_{1}+h_{1},x_{2}]=0, \\
& N(x_{2}, x_{2}+h_{2}]=1,\dots, N(x_{n-1}+h_{n-1},x_{n}]=0, \\
& N(x_{n},x_{n}+h_{n}]=1, N(x_{n}+h_{n},t]=0\}
\end{split}
\end{equation}
\bigskip

\begin{fleqn}
\begin{equation}
\begin{aligned}
 & \mathrlap{\{T_{1} \in (x_{1},x_{1}+h_{1}]\dots,T_{n} \in (x_{n},x_{n}+h_{n}], N(t)=n\} = }\hspace{4em} & & & &\ \\
 & & & \{N(0,x_{1}]=0, N(x_{1},x_{1}+h_{1}] = 1, N(x_{1}+h_{1},x_{2}]=0,\\
& & & N(x_{2}, x_{2}+h_{2}]=1,\dots, N(x_{n-1}+h_{n-1},x_{n}]=0, \\
& & & N(x_{n},x_{n}+h_{n}]=1, N(x_{n}+h_{n},t]=0\}
\end{aligned}
\end{equation}
\end{fleqn}

\end{document} 

Answer 2

我建议将=符号移至第二行，并与括号右对齐，以强调这些项目在集合描述中。将括号做得大一点可能会有所帮助。

\documentclass[a4paper,12pt]{report}
\usepackage{amsmath, mathtools}

\begin{document}

\begin{equation}\label{eq:20}
\begin{split}
\MoveEqLeft[4]
\bigl\{
  T_{1} \in (x_{1},x_{1}+h_{1}],\dots,T_{n} \in (x_{n},x_{n}+h_{n}], N(t)=n
\bigr\}
\\
=\bigl\{
  & N(0,x_{1}]=0, N(x_{1},x_{1}+h_{1}] = 1, N(x_{1}+h_{1},x_{2}]=0, \\
  & N(x_{2}, x_{2}+h_{2}]=1,\dots, N(x_{n-1}+h_{n-1},x_{n}]=0, \\
  & N(x_{n},x_{n}+h_{n}]=1, N(x_{n}+h_{n},t]=0
\bigr\}
\end{split}
\end{equation}

\end{document}
