用多个花括号写出等式

Question

我试图写出这个等式，但在 tex.stackexchange.com 上没有得到足够的提示

Answer 1

这应该可以帮助你入门：

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\begin{document}
\begin{equation}
\begin{Bmatrix}
\varepsilon^{m}_{xx} \\
\varepsilon^{m}_{yy} \\
\gamma^{m}_{xy}
\end{Bmatrix}
=
\begin{Bmatrix}
\frac{\partial u}{\partial x} \\
\frac{\partial v}{\partial y} \\
\frac{\partial u}{\partial y} + \frac{\partial v}{\partial x} \\
\end{Bmatrix}
\end{equation}
\end{document}

Answer 2

一个可能的解决方案。我做了arraystrech一些修改，以便在差速器周围提供更多空间，它们有点像是相互嵌合在一起。我还为希腊字母制作了两个小宏，它们感觉有点重复。

\documentclass{article}

\usepackage{amsmath}

\newcommand\myeps[2]{\varepsilon^{#1}_{#2}}
\newcommand\mygam[2]{\gamma^{#1}_{#2}}
\renewcommand\arraystretch{1.2}

\begin{document}
\begin{equation}
  \begin{Bmatrix}
    \myeps{m}{xx} \\
    \myeps{m}{xx} \\
    \mygam{m}{xy}
  \end{Bmatrix}
  =
  \begin{Bmatrix}
    \frac{\partial u}{\partial x} \\
    \frac{\partial v}{\partial y} \\
    \frac{\partial u}{\partial y} + \frac{\partial v}{\partial y}
  \end{Bmatrix}
  ;
  \begin{Bmatrix}
    \myeps{f}{xx} \\
    \myeps{f}{yy} \\
    \mygam{f}{xy}
  \end{Bmatrix}
  =
  \begin{Bmatrix}
    \frac{\partial \theta}{\partial x} \\
    \frac{\partial \theta}{\partial y} \\
    \frac{\partial \theta}{\partial y} + \frac{\partial \theta}{\partial y}
  \end{Bmatrix}
\end{equation}
%
and the next
%
\begin{equation}
  \begin{Bmatrix}
    \mygam{(0)}{xy} \\
    \mygam{(0)}{xy}
  \end{Bmatrix}
  =
  \begin{Bmatrix}
    \theta_x - \frac{\partial w_0}{\partial x} \\
    \theta_y - \frac{\partial w_0}{\partial y}
  \end{Bmatrix}
\end{equation}
\end{document}
