为什么 tikz 连接我的节点？

Question

我用

\usepackage{pdflscape}
\usepackage{tikz}
\usetikzlibrary{automata}

我的代码如下所示

\begin{figure}
\centering
\begin{tikzpicture}
\node[draw,align=center,text width=0.16\textwidth] at (-0.34\textwidth,0) {Applet};
\node[draw,align=center,text width=0.16\textwidth] at (-0.17\textwidth,0) {Applet};
\node[draw,align=center,text width=0.16\textwidth] at (0,0) {Applet};
\node[draw,align=center,text width=0.5\textwidth] at (-0.17\textwidth,-0.7) {Java Card Operating System};
\node[draw,align=center,text width=0.3\textwidth] at (0.27\textwidth,-0.35) { Native \\ Application \vspace{8pt}};
\node[draw,align=center,text width=0.84\textwidth] at (0,-1.44) {\gls{ic} Platform};
\end{tikzpicture}
\caption{Architecture of a \gls{smartcard}}
\label{figure:smartcardarchitecture}
\end{figure}

当我编译它时，生成的图片是

我如何去掉 Applet 框之间的线条？

我也很高兴得到一些关于如何正确调整盒子高度的指导 - 但不要太复杂;-)。

'彼此Applet太近且重叠。请比较修改后的示例。我不确定你的\gls意思...

\documentclass{article}

\usepackage{pdflscape}
\usepackage{tikz}
\usetikzlibrary{automata}

\begin{document}
and my code looks like this

\def\gls{\MakeUppercase}

\begin{figure}
\centering
\begin{tikzpicture}
\node[draw,color=red,align=center,text width=0.16\textwidth] at (-0.34\textwidth,0) {Applet};
\node[draw,align=center,text width=0.16\textwidth] at (-0.17\textwidth,0) {Applet};
\node[draw,align=center,text width=0.16\textwidth] at (0,0) {Applet};
\node[draw,align=center,text width=0.5\textwidth] at (-0.17\textwidth,-0.7) {Java Card Operating System};
\node[draw,align=center,text width=0.3\textwidth] at (0.27\textwidth,-0.35) { Native \\ Application \vspace{8pt}};
\node[draw,align=center,text width=0.84\textwidth] at (0,-1.44) {\gls{ic}
 Platform};
\end{tikzpicture}
\caption{Architecture of a \gls{smartcard}}
\label{figure:smartcardarchitecture}
\end{figure}
