Tikz：矩形分割内部分离

Question

使用tikz和tikzshapes，创建两个分割矩形。每个部分可以有不同的内部分离吗？

梅威瑟：

\documentclass[]{article}
\usepackage{tikz}
\usetikzlibrary{shapes}

\begin{document}
\begin{tikzpicture}[every text node part/.style={align=left}]
\node[rounded corners=0.5ex,inner sep=0.75ex,rectangle split, rectangle split parts=2, rectangle split part align={left},rectangle split part fill={gray,yellow}]
{
Energy Conversion in an IC Engine

\nodepart{two}
Chemical Energy $\rightarrow$ Heat Energy $\rightarrow$ Mechanical Energy
};
\end{tikzpicture}
\end{document}

期望输出（其中底部具有更多内部分离）：

Answer 1

您只需添加一个不可见的高物体即可。

\documentclass[]{article}
\usepackage{tikz}
\usetikzlibrary{shapes}

\begin{document}
\begin{tikzpicture}[every text node part/.style={align=left}]
\node[rounded corners=0.5ex,inner sep=0.75ex,rectangle split, rectangle split
parts=2, rectangle split part align={left},rectangle split part
fill={gray,yellow}]
{
Energy Conversion in an IC Engine

\nodepart{two}
\vphantom{$\vcenter{\vspace{2em}}$}%
Chemical Energy $\rightarrow$ Heat Energy $\rightarrow$ Mechanical Energy
};
\end{tikzpicture}
\end{document}

Answer 2

该tcolorbox包装设计用于制作像这样的盒子。

\documentclass{article}
\usepackage{tcolorbox}
\begin{document}
\begin{tcolorbox}[
    boxrule=0pt, left=.5ex, width=.75\textwidth,
    colback=yellow, colframe=gray, coltitle=black,
    title=Energy Conversion in an IC Engine
]
Chemical Energy $\rightarrow$ Heat Energy $\rightarrow$ Mechanical Energy
\end{tcolorbox}
\end{document}
