如何使数组中两行之间的距离更大？

Question

我在文档中找到了数学公式mathdesign，看起来很漂亮很优雅

当我尝试按照它的样子输入时，我得到的结果总是不如原来的那么好。

我使用的代码是

\begin{equation}\label{test}
\newcolumntype{Y}{>\displaystyle c}
  \left|\frac{D(u,v)}{D(x,y)}\right|=
  \left|
  \begin{array}{@{}YY@{}}
    \frac{\partial u}{\partial x} & \frac{\partial u}{\partial y} \\
    \frac{\partial v}{\partial x} & \frac{\partial v}{\partial y}
  \end{array}
  \right|
  \neq
  0
  \quad
  \text{and}
  \quad
  \left|\frac{D(x,y)}{D(u,v)}\right|=
  \left|
  \begin{array}{@{}YY@{}}
    \frac{\partial x}{\partial u} & \frac{\partial x}{\partial v} \\
    \frac{\partial y}{\partial u} & \frac{\partial y}{\partial v}
  \end{array}
  \right|
  \neq
  0
\end{equation}

产生

我认为两行之间的距离太窄了。我怎样才能得到原点结果？谢谢 :)

您可以通过向 newline 命令添加可选参数来指定行之间的距离，如下所示：\\[2.5ex]

\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage{array}
\pagestyle{empty}
\begin{document}
\begin{equation}\label{test}
\newcolumntype{Y}{>\displaystyle c}
  \left|\frac{D(u,v)}{D(x,y)}\right|=
  \left|
  \begin{array}{@{}YY@{}}
    \frac{\partial u}{\partial x} & \frac{\partial u}{\partial y} \\[2.5ex]
    \frac{\partial v}{\partial x} & \frac{\partial v}{\partial y}
  \end{array}
  \right|
  \neq
  0
  \quad
  \text{and}
  \quad
  \left|\frac{D(x,y)}{D(u,v)}\right|=
  \left|
  \begin{array}{@{}YY@{}}
    \frac{\partial x}{\partial u} & \frac{\partial x}{\partial v} \\[2.5ex]
    \frac{\partial y}{\partial u} & \frac{\partial y}{\partial v}
  \end{array}
  \right|
  \neq
  0
\end{equation}

\end{document}
